1. About the Journal

Angewandte Chemie International Edition (in English) and Angewandte Chemie (in German) are owned by Gesellschaft Deutscher Chemiker (GDCh) (the German Chemical Society) and are published by Wiley-VCH. All general formal aspects of manuscript styling are the same within the Angewandte Chemie, ChemPubSoc Europe, and Asian Chemical Editorial Societies (ACES) family of journals.

"Angewandte Chemie" is synonymous with leading chemical research across all fields of chemistry and adjacent disciplines. Angewandte Chemie International Edition and Angewandte Chemie publish 52 issues in print and online (in the Wiley Online Library) per year and all articles are available online weeks before they appear in an issue. The journals publish (length restrictions are provided in parentheses as characters with spaces): Reviews (ca. 100000 char), Minireviews (ca. 40000 char), Research Articles (ca. 40000 char), Communications (ca. 20000 characters), Essays (ca. 25000 char), Viewpoints (ca. 20000 char), and Highlights (ca. 9000 char). Submissions are evaluated by full-time professional editors and are subject to peer review. Contributions that are not considered suitable for the journal will be returned to the authors without external review. All other contributions are sent to two or more independent referees. Angewandte Chemie operates a strict single-blind peer-review process and the final decision is made by the Editor. Learn more about the peer-review process. Upon submission, authors are encouraged to suggest referees with whom they have not previously collaborated.

Contributions should be in British or American English. Communications are published in English in the German edition of Angewandte Chemie (with the exception of the keywords and the graphical abstract); however, authors who are fluent in German may also supply a translation of their Communication. The main correspondence author will receive page proofs (in English and, if applicable, in German) as PDF and Word files, and after publication of the article, a print copy. In the case of a Review, the correspondence author will also receive a complimentary PDF (in both languages) that allows 50 printouts. Reprints and high-resolution PDFs can be ordered for a reasonable price, and ideally when submitting the corrected galley proofs. Please see the Copyright Transfer Agreement for terms of use of both the Accepted Version and the Final Published Version.

Authors are requested to submit their manuscripts through our online submission service, Editorial Manager (www.editorialmanager.com/anie); please note that ORCID registration and authentication is required for submission of the manuscript, and the submitting author must be a corresponding author. The submitting author can follow the progress of the manuscript on the personal homepage (www.editorialmanager.com/anie), which is created upon initial registration.

To make sure that references to these journals are correctly recorded and resolved (for example in CrossRef, PubMed, or ISI Web of Knowledge), please use the following abbreviated title in any citations: Angewandte Chemie International Edition is "Angew. Chem. Int. Ed." and Angewandte Chemie is "Angew. Chem."

Please Cite both the International and German editions simultaneously; e.g., [1] a) N. Compton, Angew. Chem. Int. Ed. 2019, 58, 4–8; Angew. Chem. 2019, 131, 4–8; b) N. Compton, Angew. Chem. Int. Ed. 2018, 57, 4–6; Angew. Chem. 2018, 130, 4–6.

We recommend that authors provide a link to their publication on their homepage through the Digital Object Identifier (DOI).

Queries regarding manuscripts should be sent to angewandte@wiley-vch.de.

Information for Authors

Angewandte Chemie, ChemPubSoc Europe, and Asian Chemical Editorial Society (ACES) journals will consider submitted papers that have been previously 1) posted as a preprint on a non-profit community preprint server such as ChemRxiv, bioRxiv, and arXiv, or 2) published as a thesis prepared toward completion of a graduate degree at a university or technical institute of learning. Only the original submitted version of a manuscript is allowed to be posted as a preprint. Manuscripts previously published in other contexts will not be considered.

The authors must inform the Editor of manuscripts submitted, soon to be submitted, in press or published at other journals or posted on any preprint server, that have a bearing on the manuscript being submitted to any journal in the Angewandte Chemie, ChemPubSoc Europe, and ACES journal family.

In the case of preprints, journals require that the material is not communicated with the media prior to publication of the paper in the journal family.

If the manuscript is a revised or extended version of a manuscript previously rejected by the receiving journal, the author must inform the editor about the previous submission in the cover letter and explain in detail which changes have been made. The journal may examine the prior history of manuscripts submitted to, but not accepted in, other Wiley-VCH journals, including Chemistry and Materials journals. To facilitate administration and evaluation, authors are encouraged to disclose such prior submissions in their cover letter and to address any reviewer comments, when applicable. Submissions to the receiving journals may not be under evaluation at any other journal at the time of submission.

The contributions of each author should be specified as "Contributor Roles" when all other information on the author is entered into Editorial Manager. Every author must be informed about the submission and must have agreed to the submitted version. Honorary authorship is forbidden.

For detailed advice about the Legal and Ethical Responsibilities of authors, including ethical declarations relating to human and animal experiments, conflict of interest, and copyright see Section 5 and the EuCheMS ethical guidelines.

In the event of acceptance, papers can be published online as Accepted Articles prior to editing and proofing. For more detail, including information about Open Access, see Section 4.

2. Article Types

Angewandte Chemie, ChemPubSoc Europe, and ACES journals collectively publish the following article types: Reviews, Minireviews, Communications, Full Papers/Research Articles, Essays, Concepts, Highlights, Correspondence, and Corrigenda. Consult "1. About the Journal" for a list of all article types offered.

For detailed information on Manuscript Preparation see Section 3.

All templates are compiled under "Author Guidelines" on the journal′s webpage.

Reviews (length up to 14000 words, ca. 100000 characters, including footnotes, literature citations, Tables, and Figure captions) should be written by leading experts and deal with topics of high current interest in any area of chemistry. Rather than an assembly of detailed information with a complete literature survey, a critically selected treatment of the material is desired; unsolved problems and possible developments should also be discussed. Reviews should be divided into numbered sections. The Review starts with an abstract (length up to 150 words, ca. 1000 characters, no references) that should summarize the contents of the article and stimulate the readers′ interest. The Introduction should introduce non-specialists to the subject in a clear manner. A Review should conclude with a section titled "Summary and Outlook", in which the achievements and new challenges of the subject are presented succinctly. Biographical sketches (maximum length 84 words, ca. 560 characters) and portrait-quality photographs of the correspondence authors should be submitted.

Minireviews (length up to 5600 words, ca. 40000 characters, including footnotes, literature citations, Tables, and Figure captions) should present current topics in a concise Review style. Minireviews offer the flexibility to treat topics at a time when a Review would still be premature or inappropriate. The general format is the same as that outlined for Reviews (above).

Communications and Full Papers/Research Articles present the results of experimental or theoretical studies of general interest or great importance to the development of a specific area of research. A short cover letter justifying why the manuscript should appear in the journal should be submitted. A Communication should be no longer than 2500 words (ca. 20000 characters), including all references, footnotes, and Tables. Chemical formulae, Figures, and Schemes may also be added. Full Papers (no length restrictions)/Research Articles (length up to 5600 words, ca. 40000 characters) may contain an Experimental Section and/or Computational Methods. However, the editorial office requests that only the most essential parts of your experimental procedures are included in the Experimental Section; the rest should be presented in the Supporting Information. Angewandte Chemie, ChemPubSoc Europe, and ACES journals will not publish Full Papers/Research Articles that consist mainly of results reported in previous Communications with an added Experimental Section.

Essays (length up to 3500 words, ca. 25000 characters) describe themes from every aspect of chemistry, including the philosophy or history of science. Use of unpublished results from original research should be limited. Known topics should be discussed illuminatingly and critically from a new vantage point, and they should be suitably illustrated. A biographical sketch (maximum length 80 words, ca. 560 characters) and a portrait-quality black-and-white photograph of the author should be submitted. Essays should be written by one author only.

Viewpoints (length up to 2800 words, ca. 20000 characters) are opinion-based contributions that convey the author′s thoughts on important developments in a specific area and the implications for future research. Viewpoints may be controversial, and while the author should put forward their own point of view, counter arguments should not be ignored but rather refuted through discussion.

Concepts (length up to 2400 words, ca. 17000 characters) are short articles that emphasize the general concepts that have guided important developments in a specific area and their implications for future research. The reference section should only include the key papers that have contributed to conceptual advances in the field under review, rather than being fully comprehensive. The author should aim to provide the non-specialist reader with a useful guide, and the expert with a new angle on a familiar problem. Concept articles may be organized as the author wishes, but should include a short Abstract (approximately 80–140 words, no references) that succinctly describes the concepts under discussion. Articles should consist of around 10 pages of text, including references, Tables, and legends. Liberal use of Schemes, Figures, and color is encouraged.

Highlights (length up to 1200 words, ca. 9000 characters) describe very important recent results of original research (preferably published online within the last month), in general by a third person, with a view to instruct and to highlight the significance of the findings. The results should be presented clearly and as succinctly as possible, without the comprehensive details required for an original article. Highlights should include only essential formulae and figures, as well as not more than 15 references. A Highlight should not be longer than two pages. Highlights should have no more than two authors, who should not have affiliations with the author(s) of the work being highlighted.

Correspondence or Comments on publications in Angewandte Chemie, ChemPubSoc Europe, and ACES journals are welcome if they contribute to the scientific discussion. The author of the publication to which the Correspondence pertains will have the opportunity to reply. This reply will be sent to the author of the Correspondence.

Scientifically incorrect or incomplete information in published articles should be corrected in a Corrigendum, which is as short as possible. All corrigenda are subject to approval by the Editor, and minor corrections will not be published. We request that authors submit the Corrigendum electronically like any other article, and that they cite the publication to be corrected, as well as its DOI. Please note: readers with questions or concerns about published articles should contact the corresponding author of the article directly. It is the author′s responsibility to formulate an appropriate response to such approaches.

3. Manuscript Preparation

Contributions should be in British or in American English. Authors should submit their manuscripts through the online submission service Editorial Manager, which can be accessed through the "Submit a Manuscript" tab under "Contribute" on the journal′s webpage. Please prepare two files (if applicable): one containing the main manuscript (single-spaced text) with all graphics and tables integrated into the text at the appropriate position; the other containing the Supporting Information (see Section 3.4).

Templates for all article types (MS Word, ChemDraw, Endnote) are available on the journal homepage in the section "Author Guidelines". Templates help to judge the length (number of pages) of an article, but they do not reflect the exact final layout. It is not compulsory to use the templates, although reviewers may find it easier to evaluate a manuscript prepared in a template. Details for the preparation of the final revised version of accepted contributions ("Production Data") are provided in the checklist in the acceptance letter.

If you use LaTeX, please send standard LaTeX files only and a PDF file of the manuscript; please do not include your own style sheets or macros. Keep your file as simple as possible. It will not be used directly to typeset your manuscript, but will be converted prior to editing and typesetting (latex2rtf). For further details, consult our "Instructions for LaTeX users" on the journal homepage in the section "Author Guidelines".

The ORCID identifier is required for the submitting correspondence author on submission of a manuscript. We encourage all authors to provide an ORCID for each co-author as well. ORCID is a non-profit registry that provides researchers with a unique digital identifier. Some funding agencies recommend, or even require, the inclusion of ORCID numbers in all published articles; authors should consult their funding agency guidelines for details. Registration is easy and free; for further information see orcid.org.

3.1. Style

Authors are asked to make their manuscripts suitable for a heterogeneous readership. Use a simple, clear style, and avoid jargon. In some cases, it might be helpful for manuscripts to be checked by a third party for correct language usage before submission; for example, Wiley English Language Editing Services.

If possible, the standard Symbol font should be used to create Greek letters, rather than special characters or graphics embedded in the text.

Nomenclature, symbols, and units: the rules and recommendations of the International Union of Pure and Applied Chemistry (IUPAC), the International Union of Biochemistry (IUB), and the International Union of Pure and Applied Physics (IUPAP) should be adhered to.

Abbreviations and acronyms should be used sparingly and consistently. Where they first appear in the text, the complete term—apart from the most common ones such as NMR, IR, and tBu—should also be given.

3.2. Structure of Articles

The Title of a publication is the key point of entry for readers, abstracting services, and search engines. Therefore, the title should be informative, attract as many readers as possible to the work, and avoid acronyms and abbreviations if possible. In the title the first letters of all words, except coordinating conjunctions, articles, and prepositions, should be capitalized. Please avoid chemical formulae in the title—they may complicate retrieval of your article by search engines or databases. No references should be cited.

Authorship is listed with the full given name and surname of each author, and an asterisk to indicate each correspondence author. A dedication line can also be included.

The address field contains the names of all authors according to research group (with academic title and all first names as initials), the complete postal address (preferably in the country′s official language), and academic or institutional email address(es) of the correspondence author(s). For the non-correspondence authors, only the address of their academic institution or company is required. The correspondence author is welcome to include the web address for their research group.

An abstract presents the motivation for the work, the methods applied, the results, and the conclusions drawn. The abstract:

1)

should reflect the contents of the paper, and the text should contain several keywords to aid retrieval of the paper online;

2)

must not contain graphics, compound numbers (please use compound names), or references, as the abstract will be searchable independently from the rest of the manuscript (e.g., in databases);

3)

should be easily accessible; keep abbreviations to a minimum;

4)

should not be longer than a maximum of 150 words (ca. 1000 characters).

An Introduction enables readers unfamiliar with the subject to become acquainted with the importance of the results presented; relevant references should be included.

Communications should not be divided into sections; however, experimental or computational details can be summarized separately under the heading Experimental Section or Computational Methods.

In Full Papers/Research Articles the presentation of Results and Discussion may be combined or kept separate. These sections may be further divided by subheadings.

In the Conclusion, the results should be summarized succinctly and with reference to the significance of the findings and, if appropriate, to the remaining challenges.

Important, ancillary information, which is relevant to the parent article but is not of sufficient general interest to include in the article itself, should be presented as Supporting Information (a PDF document that may be accompanied by additional supporting materials). The Supporting Information must be presented succinctly, in English, and may comprise additional Tables, data sets, Figures, movie files, and so on. The materials in the Supporting Information must be original and not previously published; otherwise, appropriate citations must be given. The Supporting Information is subject to peer review, and the author is solely responsible for its contents; thus, the scientific quality of the Supporting Information and the preparation of the text and graphics should be of the same standard as that in the actual publication (see Section 3.4 for reporting Experimental Data and Section 3.3 for preparation of graphical materials). The Supporting Information should start with a table of contents, and the relationships between the sections of the main article and the Supporting Information should be readily apparent.

Note that Angewandte Chemie, ChemPubSoc Europe, and ACES journals encourage authors to share data and Supporting Information pertinent to the findings described in their paper by archiving such content in an appropriate public repository/database. See the Appendix: Reporting Experimental Information and Data, Section F. Data Deposition for examples of trusted repositories and visit re3data.org or fairsharing.org to help identify registered and certified data repositories relevant to your subject area. In such cases authors should provide a link to the repository/database (see Section 3.5), which will then be published alongside the paper. Learn about sharing and citing your research data.

Acknowledgments—especially for any financial support—are given as a separate paragraph at the end of the main text.

References to the literature (or to footnotes) are typed in square brackets as superscripts after punctuation. These are numbered consecutively and listed (with the numbers in square brackets) at the end of the main body of text. References should not contain comprehensive experimental details or long explanatory text. Authors must cite relevant resources; including but not limited to scientific journals, books, databases, preprints, websites, computer programs, and so on. The DOI should be used to cite papers available online for which page numbers have not yet been assigned. See Section 3.5 for detailed formatting requirements. The reference list should be fair and informative but not excessive. Copies of cited publications not yet available publicly, and with particular significance to the contribution under consideration, should be submitted along with the manuscript. Unpublished results and lectures should only be cited in exceptional circumstances. Please double-check your references to ensure (online) links are correct; for example, by using CrossRef.

Authors should provide a short Table of Contents graphical abstract and accompanying text on the last page of the manuscript with 1) a text of up to 50 words (ca. 450 characters), 2) an image (5.5×5.0 cm (h×w) or 11×2.5 cm (h×w), font size: 6–7 point), and 3) a maximum of five alphabetized keywords in American English. At least two of the keywords should be taken from the "Keyword Catalogue" (see Section 3.6). The graphical abstract should stimulate curiosity. Repetition or paraphrasing of the title and experimental details should be avoided.

3.3. Graphics, Tables, and Multimedia

Please be aware of the ethical and copyright issues associated with production of graphical materials, including graphical abstracts and cover pictures (see Section 5).

High-quality graphical materials are an essential part of effective scientific communication and should be reproducible and legible in published media. All images (graphs, microscopy images, etc.) should be sized appropriately in a graphical program (e.g., Adobe Photoshop), and embedded in the Microsoft Word file as high resolution graphics (at least 300 dpi; .tif, .jpg, .png, or similar formats). The maximum size for one-column graphics is 8.4 cm and for two-column graphics 17.8 cm. Text should be 1.5 to 2 mm tall (about 7 or 8 point font size). All formulae, Figures, and Schemes must be legible unmagnified, when scaled for printing. Use the "insert graphic" option in Microsoft Word to embed graphical files in your word document. If a graphic contains several panels, the panels should first be combined into a single image before insertion into the manuscript text file. Within your Microsoft Word document, do not anchor or group images, and do not use formatting options in Microsoft Word (e.g., color adjustment) to alter embedded objects or graphics.

All chemical structures must be provided in ChemDraw format (.cdx). For faster processing, ensure chemical structures are embedded in the manuscript file. Use the "insert object" option in Microsoft Word to embed ChemDraw files in your document, or copy and paste the image directly from ChemDraw. The ChemDraw template provided in the Author Guidelines is set up for drawing chemical structures in the correct dimensions and font sizes. Chemical formulae should be numbered consecutively. For representation of chemical formulae, see recommendations published by IUPAC in J. Brecher, Pure Appl. Chem. 2008, 80, 277. Abbreviations such as Me, iPr, nBu, and Ph should be applied consistently. General substituents should be indicated by R, R′ or R¹, R² (not R₁, R₂ which means 1R and 2R). The spatial arrangement of the substituents should be indicated by hatched lines and solid wedges.

A Scheme is a reaction scheme containing chemical structures in which a chemical transformation occurs or a reaction mechanism is shown. A reaction that is described without chemical structures but with chemical formulae is an Equation; these are numbered consecutively as [Eq. (x)] or Equation (x).

A Figure is a graph, crystal structure, photograph, illustration, spectrum, or similar (Wiley-VCH journals do not publish Charts). A collection of chemical structures (e.g., for demonstrating reaction scope) is considered a Figure, not a Table; if this is accompanied by a chemical reaction, it should be labeled as a Scheme. Each Figure and Scheme should have a legend. Microscopy images (optical, electron, or scanning probe) should always contain a legible scale bar.

Tables are edited in the text and should be set up using the Table tools in MS Word (rather than as graphical elements); they must have a brief title and should only be subdivided by three horizontal lines (head, body, and foot). Footnotes are denoted [a], [b], [c], etc.

Animated, multimedia applications, films, and so on are welcome and are published online at no cost to the author or reader. Please refer to such applications in the article itself where appropriate. These data can be uploaded with the rest of the Supporting Information. Please use suitable compression technology to avoid exceedingly large movie files (>20 MB) for the benefit of referee and reader access times. Please ensure that your movies are saved in a common format (e.g., MPEG, AVI, QuickTime, GIF) that can be played on at least two different computer platforms (out of Windows/MacOS/Linux). If you have problems uploading large files, please contact the Editorial Office.

3.4. Experimental Data

Detailed experimental requirements are accessible in the Appendix: Reporting Experimental Information and Data.

For Full Papers, summarized data for all characterization techniques should be reported in the manuscript, whereas full spectra, chromatograms, and diffraction patterns should be given in the Supporting Information. For Communications and Research Articles, all characterization data may be moved to the Supporting Information.

The Experimental Section should give sufficient detail to enable others to repeat and compare your work. In theoretical papers, technical details such as computational methods should likewise be confined to an appropriately named section. Equipment, complete with make and model number, and conditions used for the measurement of physical data should be described at the beginning of the experimental section. If practical, authors should use a systematic name (IUPAC or Chemical Abstracts) for each title compound in the Experimental Section. Do not use computer programs to generate elaborate systematic names or use long, multiline compound names; in such cases general descriptors, such as compound 2, dendrimer 3, or alcohol 4, should be used. When preparing your manuscript and the Supporting Information, please ensure that the compound numbers used in both documents match.

Physical data should be given in the following order: R_f=0.38 (CHCl₃/MeOH 9:1); m.p./b.p. 20°C; [α]D20=−13.5 (c=0.2 in acetone); ¹H NMR (200 MHz, [D₈]THF): δ=7.64–7.48 (m, 6H; Ar-H), 1.33 (q, ³J_H,H=8 Hz, 2H; CH₂), 0.79 ppm (s, 3H; CH₃); ¹³C NMR (75 MHz, CDCl₃): δ=72.5 (CCH), 26.8 (s; CH₃), 6.5 ppm (d, ¹J_C,P=156.9 Hz; CHP); IR (Nujol): ν˜=1780 (vs), 1790 (s) cm⁻¹ (C=O); UV/Vis (n-hexane): λ_max (ε)=320 (5000), 270 nm (12000 mol⁻¹dm³cm⁻¹); fluorescence (CH₂Cl₂): λ_ex=435.5 nm; λ_em=659, 726 nm; MS (70 eV): m/z (%): 108 (20) [M]⁺[TR ion], 107 (60) [M−H]⁺, 91 (100) [C₇H₇]⁺; HRMS (ESI): m/z calcd for C₃₂H₄₇NO₅+Na⁺: 548.3352 [M+Na]⁺; found: 548.3331; elemental analysis calcd (%) for C₂₀H₃₂N₂O₅: C 63.14, H 8.48, N 7.36; found: C 62.88, H 8.41, N 7.44.

3.5. Reference Section

In the list of references, the names of all authors should be given in upper- and lowercase, starting with the initials of first names followed by the surname. The penultimate and last names should be separated by a comma (not by "and"). Please double-check your references to ensure online links are correct; for example, by using CrossRef. The Endnote template provided on the journal′s homepage under "Author Guidelines" will facilitate reference management.

A summary of the formatting style for references is provided below:

Journal citations: Journal titles should be abbreviated in accordance with the "Chemical Abstracts Service Source Index" (CASSI; no commas appear in the journal names). Examples: H. Frey, Angew.

3.6. Basic Keyword List

An interjournal browsing facility (automatic links to lists of thematically related contributions with a click of the mouse) has been developed for the readers of the journal family. Refer to the common keyword catalogue in American English. At least two of the maximum of five keywords assigned to an article should come from this list, to enhance the discoverability of your content in Special Collections.

This keyword list is a "living" catalogue, which is flexible enough to absorb new developments in chemistry. We therefore welcome all suggestions from our readers and authors that might improve its user-friendliness.

4. Accepted Manuscripts

4.1. Workflow

To facilitate rapid dissemination to the scientific community, authors are given the option to publish an "Accepted Article" immediately after their paper has been accepted, and prior to the editing and proofing process. Accepted Articles can be cited using the Digital Object Identifier (DOI). The final text version of the Accepted Article, which contains graphics, must be uploaded as a single PDF file. The file will appear automatically in the Accepted Article section of the journal′s homepage, and is thus the responsibility of the author. If applicable, the Supporting Information must also be submitted as a PDF file under "Supporting Information for Accepted Article". If the manuscript file is submitted under the incorrect file item, it will not be published online. Please note: authors are responsible for the content of an Accepted Article. Any changes to the published Accepted Article will be made only through the editing and proofing process. The cover page for the Accepted Article is assembled from the data entered into Editorial Manager; please ensure that the manuscript title, abstract, author names, and the order of the author names and affiliations are correct at the point of submission.

Further instructions for preparation of the edited and proofread Version of Record are provided in a separate e-mail to the author after acceptance of a manuscript. After copy-editing the correspondence author will receive galley proofs via Editorial Manager; these should be returned to the editorial office as soon as possible. The Version of Record will be published online in Early View as soon as possible after editing and proofing, and may be different to the Accepted Article. Readers should therefore obtain the Version of Record from the journal website to ensure accuracy of information.

Where a correction is required to the Version of Record after publication, authors should submit a Corrigendum (see Section 2). Please contact the Editorial Office in such cases.

Appendix: Reporting Experimental Information and Data

The Experimental Section should give sufficient detail to enable others to repeat and compare your work. Equipment and conditions used for the measurement of physical data should be described at the beginning of the Experimental Section, and the make and model of instruments employed in the synthesis and characterization of compounds should be mentioned. Detailed guidance is provided below.

A. Synthetic Procedures

Literature references to known but non-commercial compounds should be given, and hazardous chemicals, equipment and techniques must be emphasized. If practical, authors should use a systematic name (IUPAC or Chemical Abstracts) for each title compound in the Experimental Section. Do not use computer programs to generate elaborate systematic names or use long, multiline compound names; in such cases general descriptors, such as compound 2, dendrimer 3, or alcohol 4, should be used.

New synthetic procedures should contain reactant quantities in weight or volume and molar units. Equipment details, such as reaction vessel, type of heating (conventional, microwave, or photoirradiation), irradiation wavelength, optical irradiance, cut-off filters, and details of purification techniques and solvents, among others. Yields of purified products should be in weight and percentage (for example, 109 mg, 95%). Physical data should be quoted with decimal points and negative exponents (for example, 25.8 JK⁻¹mol⁻¹). If chromatographic methods are used for purification, the nature of the stationary phase and thin-layer chromatography data/retention factor (for example, R_f=0.38 (CHCl₃/MeOH 9:1)) should be provided. Please note that reactions following a new synthetic procedure can be conducted on a small scale, but at least one example should be at a scale of 1 mmol.

B. Characterization

B1. Characterization of Compounds and Materials

The structure and composition of all compounds and materials central to the manuscript must be disclosed in the main text or in the Supporting Information, including commercial and proprietary products, pure materials, and mixtures. Manuscripts reporting results using undisclosed material compositions may be returned without external review.

All new organic, organometallic, and inorganic compounds, and materials must be fully characterized by appropriate analytical methods with sufficient evidence for composition, structure, and purity (for example, elemental analysis, ¹H and ¹³C NMR spectroscopies, high-resolution mass spectrometry, mass spectrometry, IR spectroscopy, specific rotation, physical state and melting point, X-ray crystallography, electron microscopy, X-ray diffraction, etc.). The identity and bulk purity of compounds and materials should be verified with elemental analysis or, in exceptional circumstances, by another appropriate method. For instance, when the compound is unstable or not available in sufficient quantities for complete analysis, the exact relative molecular mass obtained by high-resolution mass spectrometry and clean ¹H and ¹³C NMR spectra (appended to the Supporting Information for inspection by the referees) should be supplied. Reasons should be provided if a type of data could not be obtained for a compound or compound class.

In any cases where elemental analysis cannot be carried out (for example, for air-sensitive compounds) an explanation for the omission or inaccuracy of this data should be given, alongside additional evidence for purity. HPLC or GC chromatograms are suitable, but other techniques (for example, NMR spectroscopy or powder X-ray diffraction) will be considered.

For known organic, organometallic, and inorganic compounds, characterization by ¹H and ¹³C NMR spectroscopies and mass spectrometry is sufficient and purity should be verified. A reference to the fully characterized compound should be provided. Any soluble organometallic or inorganic diamagnetic compound with an organic fragment should be characterized using NMR spectroscopy (¹H, ¹³C, and any other appropriate nucleus) in the same manner as organic compounds. For soluble paramagnetic compounds (for example, Cu^II complexes), paramagnetic NMR techniques are encouraged but not essential.

Reporting of single-crystal X-ray structures is encouraged for crystalline solids; however, such structures cannot be used as the only means of characterization as they do not necessarily represent the bulk material. Powder X-ray diffraction data can be submitted as evidence for the purity of a bulk material—ideally in comparison to a calculated diffraction pattern. For micro- and nanostructured materials, detailed information about both the composition and morphology (for example, adsorption–desorption isotherms, surface area, porosity, etc.) should be provided.

Data collected for a sample may be subject to measurement variations (for example, device settings, sample preparation, sample dimensions, etc.). In such cases authors must not only report the important settings of the measurement and data specific for the sample (for example, sample dimensions or mass) but also make the data comparable. The technique and the parameters used for this purpose (for example, normalization) must be reported.

B2. Characterization Techniques

Please note: manipulation of spectra to misrepresent data is unethical and will not be tolerated.

Nuclear magnetic resonance spectroscopy: Proton and carbon resonances must be provided for each new compound in the Experimental Section or in the Supporting Information; solvent and instrument frequencies are required. Depending on the compound, other resonances, such as ¹⁹F, ²⁹Si, or ³¹P should be added. NMR spectra should have sufficiently high signal-to-noise ratios so that all peaks can be adequately resolved.

¹H NMR resonances should be reported to the nearest 0.01 ppm. Multiplet abbreviations, number of atoms represented by each signal, and coupling constants should be provided; for example, ¹H NMR (200 MHz, [D₈]THF, 25°C, TMS): δ=7.64–7.48 (m, 6H; Ar–H), 1.33 ppm (q, J=8 Hz, 2H; CH₂). Mutually coupled protons in ¹H NMR spectra must be quoted with precisely matching J values to assist thorough interpretation. In instances where computer print-outs provide ambiguous readings, mean J values should be quoted that are rounded to the nearest decimal point.

¹³C NMR resonances should be reported to the nearest 0.1 ppm. Provide resonances with high precision only in case of closely spaced signals. The number of attached hydrogen atoms can also be included; for example, ¹³C NMR (75 MHz, CDCl₃, 25°C, TMS): δ=72.5 (CCH), 26.8 ppm (CH₃). Angewandte Chemie, ChemPubSoc Europe, and ACES journals encourage the use of "Wiley SSR", the free ¹³C NMR data-checking service from Wiley and Wiley-VCH developed by Wolfgang Robien (University of Vienna, Austria), which can be used to check the accuracy of ¹³C NMR assignments. Before you submit your manuscript, you may wish to submit key compounds to this service. To use the service, you can log in with an existing Wiley Online Library username and password or you can register with your email address.

Copies of the ¹H and ¹³C NMR spectra of all key intermediates and all final products must be included in the Supporting Information. The spectra must be those resulting from the specific reactions reported in the manuscript and not copies from previous syntheses of the same compounds. Each spectrum must be legible and should be labeled with the compound number used in the manuscript and an image of the structure. The minimum chemical shift range for ¹H NMR spectra should be −1 to 10 ppm and for ¹³C NMR spectra −10 to 200 ppm. All peaks should be labeled and integrated.

Infrared spectroscopy: It is not necessary to provide a full list of IR stretches. Only those signals that are diagnostic of the compound′s functional groups need to be listed. The band frequencies should be given to the nearest 1 cm⁻¹ and their intensity should be provided (very strong (vs), strong (s), medium (m), weak (w), broad (br)); for example, IR (KBr): ν˜=1780 (vs), 1790 (s) cm⁻¹ (C=O).

Mass spectrometry (MS): It is not necessary to provide a full list of MS peaks. Only those signals for which the molecular fragment can be identified need to be listed. Molecular ion peaks, and any other fragmentation peaks, should be reported in comparison to the calculated mass for the ion. Please use an ionization technique suitable for your compound. Relative intensities of the signals should be provided; for example, MS (EI, 70 eV) m/z (%): 173 (32), 171 (100) [M+H]⁺.

Elemental analysis or high-resolution MS (HRMS): Data should be provided to an accuracy within ±0.4% or ±0.003 of the calculated values, respectively. Elemental analysis; for example, Elemental analysis calcd for C₂₀H₃₂N₂O₅: C 63.14, H 8.48, N 7.36, found: C 62.88, H 8.41, N 7.44. High-resolution mass spectrum; for example, HRMS (ESI) m/z [M+Na]⁺ calcd for C₃₂H₄₇NO₅: 548.3352, found: 548.3331. For compounds where elemental analysis data is not provided, the HRMS data should be accompanied by NMR spectra with sufficiently high signal-to-noise ratios.

Note that elemental analysis data must be provided for papers detailing the isolation and structure elucidation of natural products.

UV/Vis and fluorescence spectroscopy: If UV/Vis or fluorescence spectroscopy data are discussed in the manuscript, the following data should be provided in the Experimental Section of the Supporting Information, along with any copies of the corresponding spectra.

UV/Vis absorptions (peak, extinction coefficient); for example, UV/Vis (n-hexane): λ_max (ε)=320 (5000), 270 nm (12000 mol⁻¹dm³cm⁻¹).

Fluorescence excitation and emission; for example, fluorescence (CH₂Cl₂): λ_ex=435.5 nm, λ_em=659, 726 nm.

X-ray absorption spectroscopy (XAS): Collection and treatment of XAS data require specialized knowledge. Please consult a beamline scientist or other experienced person to ensure the appropriate steps are taken to collect, process, and interpret XAS data correctly. The Athena User′s Guide provides general guidance for XAS data processing.

Specific rotation: Specific rotations following [α]=(100∙α)/(lc) should be provided for isolated and synthesized natural products as well as for other enantioenriched compounds; for example, [α]D20=−13.5 (c=0.2 in acetone). For new compounds that are chiral, HPLC or GC traces should be included in the Supporting Information.

Physical state and melting point: A description of the physical state and color of a new compound should be given; for example, yellow needle-like crystals. Melting point ranges should only be provided for crystalline compounds; for example, mp: 90.2–91.2°C.

Isomeric mixtures: Where isomeric mixtures are reported, such as diastereomeric or enantioenriched mixtures, please provide percentage compositions and information about how these values were obtained (for example, NMR spectroscopy, HPLC, etc.). If certain spectroscopic signals (for example, NMR signals) can be attributed to either of the isomers, these data should be reported in separate lists and not in combined lists.

Microscopy images should be captured at an appropriate magnification to show a representative sample. When high-magnification images of selected particles are used they must be supplemented by low-magnification images of the broader sample, and the use of histograms and statistics to describe size and shape distributions is encouraged.

Crystallographic data may be provided as Supporting Information and must be deposited using the joint Cambridge Crystallographic Data Centre (CCDC) and FIZ Karlsruhe deposition service (see F. Data Deposition). Authors must deposit their data before submitting their manuscript so that referees can retrieve the information directly from the data repository. Please use the free online service CheckCIF provided by the International Union of Crystallography to verify the quality of crystal structure analysis. Any ′level A′ alerts should be addressed before submission, or otherwise explained within the CIF using the Validation Reply Form (VRF). To aid retrieval, the name of the database and the deposition number(s) must be stated in the part of the manuscript where the respective structure or sequence determination is described. If data are subsequently revised prior to publication, please ensure the latest version has been deposited and that the data deposited with the database are identical to those reported in the manuscript.

If a crystal structure analysis is not an essential part of the paper, only a footnote is required indicating where the detailed results can be found. Otherwise, the following data should be given in the manuscript: crystal dimensions, crystal system, space group, unit cell dimensions and volume, ρcalcd, 2θ_max, radiation, wavelength, scan mode, temperature of measurement, no. of measured and independent reflections, no. of reflections included in refinement, σ limits, whether and how Lorentzian polarization and absorption corrections were performed (μ, min/max transmission), method of structure solution and program, method of refinement and program, no. of parameters, treatment of H atoms. R, wR, whether refined against |F| or |F²|, residual electron density, and the database in which the detailed results are deposited. An ORTEP-type plot that merely confirms the structure of a synthetic intermediate should not be included.

C. Catalysis

Catalytic activity should be reported as turnover frequency (TOF) or mass-specific activity. For heterogeneous catalysts, surface-specific activity should be reported. Evidence of catalytic performance should be provided, including mass balance, fundamental kinetic parameters, and appropriate controls such as system measurements in the absence of catalyst.

The stability of catalysts must be tested, preferably at intermediate conversion levels, and a deactivation path should be proposed. To this end, heterogeneous catalysts should be characterized both before and after reaction.

Catalyst recycling should be tested for at least five cycles and time-on-stream should be provided for industrially relevant catalysts. Although reporting product yield as a function of cycle is acceptable, reaction rates as a measure of recycling efficiency are preferred.

For synthetic methods, a selection of substrates illustrative of the scope of the reaction should be made, and the isolated yields of the corresponding purified products should be reported. Product yields determined by HPLC or GC are considered indicative of a preliminary catalytic study.

Enantiomeric purity can be expressed either as enantiomeric excess (ee) or enantiomeric ratio (e.r.). The proportions of diastereomers are expressed as a diastereomeric ratio (d.r.).

If computational results are part of the work, they must be complementary to the experimental results and should offer significant insight into the topic under investigation.

For manuscripts dealing with the use of enzymes in biocatalysis, the following information must be provided: supplier of commercially available enzymes (company name, city, country) accompanied with information about purity, and preferably units and activity test information. For recombinantly produced enzymes, please provide DNA and/or protein sequences, the vector and expression host used (add reference number if deposited on a database; see F. Data Deposition). Additionally, the method for production and isolation of the enzyme, purification method, proof of purity, and the activity test used should be stated.

Benchmarking of photo- and electrocatalysts: Where possible, the performance of photocatalysts and electrocatalysts should be benchmarked against known standards; for example, the electrocatalytic hydrogen evolution and oxygen evolution reactions over Pt/C and RuO₂, respectively.

D. Energy Storage and Conversion

In these systems small changes in sample geometry, weight, preparation, and measurement setup can have a dramatic influence on the results. With record amounts of data published each year, it is mandatory that such claims are not only reproducible but also comparable to similar systems. Hence, authors are encouraged to report the experimental factors influencing the properties and the experimental setup as accurately as possible. This includes, but is not limited to, supplier and purity of chemicals, synthesis method, electrodes used, applied bias, scan rates, irradiation type and intensity, and device structure.

To make data comparable, it is essential that the material is compared to the current state-of-the-art material. Where possible and applicable, the data should be normalized. This can be done using weight, surface area, time, any combination of these, or any other suitable means. However, it is important to provide unambiguous information about how specific data were calculated, either in the manuscript itself or in the Supporting Information. Useful information also includes stability tests, reporting C rates (rather than currents), or gas evolution rates.

E. Computational chemistry

For manuscripts that include the results of computational chemistry, the authors should include all the details that will enable other scientists to reproduce the results. Results obtained from methods that are neither described in the manuscript nor in previous published reports are not acceptable for publication. Computational details, including data such as force field parameters and equations defining the model, can be included in the paper itself or in the Supporting Information. Alternatively, references to the location of these data in the open literature can also be provided. Software used for calculations must be properly cited. References to the methods upon which the software is based must be provided. Submissions, including the results of electronic structure calculations, should include the geometries of all the stationary points reported, which should be reported with their relative energies (as Cartesian coordinates in the manuscript or as Z matrices in the Supporting Information), along with their computed absolute energies (Hartree). When appropriate, the number of imaginary frequencies should be reported to enable identification of stable structures.

F. Data Deposition

Biological and medicinal chemistry: Deposition of the following types of data in the corresponding public repositories is encouraged and accession numbers must be provided.

DNA, RNA, and protein sequences: Genbank/European Nucleotide Archive (ENA)/DDBJ, Protein DataBank, and UniProt.

Structures of biological macromolecules: Worldwide Protein Data Bank members (RCSB PDB, BMRB, PDBe, and PDBj) if any structures have been determined by X-ray crystallography. PDB Validation Reports from the EMDataBank and Nucleic Acid Database (NDB) should be provided for peer-review purposes.

Physical chemistry: Authors are encouraged to share their data and other artefacts supporting their results by archiving this information in an appropriate public repository. Authors should include a data accessibility statement, including a link to the repository they have used, for publication alongside their article.
