Notice to Authors 2014

General Information

Chemistry—A European Journal was founded by the German Chemical Society and VCH. It is now jointly owned by the chemical societies of Austria (GÖCh), Belgium (SRC and KVCV), the Czech Republic (ČSCH), France (SFC), Germany (GDCh), Greece (AGS), Hungary (MKE), Italy (SCI), the Netherlands (KNCV), Poland (PTCh), Portugal (SPQ), Spain (RSEQ), Sweden (SCS), and Switzerland (SCG), and is published by Wiley-VCH. The journal publishes 52 issues per year and contains papers from all fields of chemistry.

Contributions should be in English, but may be accompanied by an abstract in the language of the authors. The correspondence author will receive page proofs (in most cases as compressed PDF files); corrected page proofs should be returned to the Editorial Office within three days. The correspondence author will also receive a reprint PDF file, restricted to 25 printouts, free of charge. Manuscripts will be edited with a view to brevity and clarity. Queries regarding manuscripts should be sent to

All contributions are subject to peer review.

The authors must inform the Editor of manuscripts submitted, soon to be submitted, or in press at other journals that have a bearing on the manuscript being submitted to Chemistry—A European Journal. Chemistry—A European Journal does not publish manuscripts that have already appeared in print or electronically. If the manuscript is a revised version of a manuscript previously rejected by Chemistry—A European Journal the author must inform the Editor about the previous submission in the cover letter and explain in detail the changes that have been made. The Best Practice Guidelines on Publishing Ethics: A Publisher´s Perspective and the Ethical Guidelines for Publication in Journals and Reviews issued by the European Association for Chemical and Molecular Sciences (EuCheMS) are followed and applied by Chemistry—A European Journal; the latter guidelines are similar to the Ethical Guidelines to Publication of Chemical Research of the American Chemical Society. In particular, authors should reveal all sources of funding for the work presented in the manuscript and should declare any conflict of interest.

If the manuscript is a revised/extended version of a paper previously rejected by Chemistry—A European Journal or any of the ChemPubSoc Europe journals or other Wiley-VCH journals (e.g., Angewandte Chemie, Advanced Materials, Advanced Functional Materials, etc.) then the authors must inform the Editor of the previous submission, that is, give the previous manuscript number under Additional Information, enter their cover letter under "Enter Comments" and explain, in detail, the changes and revisions that have been made.

Corrections after "Early View" and before issue publication will be accepted only if formal aspects or "misprints" are concerned. For all other corrections, such as those regarding scientifically incorrect or incomplete information, a Corrigendum has to be submitted. Please contact the Editorial Office in such cases.

If authors have to or want to make their publications freely available from the moment they are published (Open Access), Chemistry—A European Journal offers such a service. In the OnlineOpen section on our homepage you can find all of the information about this subject. Chemistry—A European Journal also complies with the request or mandate from research funding agencies, for example, the US National Institutes of Health (NIH), to make manuscripts freely available online 12 months after publication of the article in the unedited and not proof-read form after acceptance. To guarantee that your publication is uploaded correctly in PubMed, please make sure that 1) the NIH grant numbers are free from misspellings (that is, no small o instead of a 0, no small i instead of a 1, no spaces or hyphens, etc.) and 2) the e-mail address that is known at NIH/PubMed is identical to the one given in the publication. In general, we recommend that authors link to their Chemistry—A European Journal publication on their homepage through the "Digital Object Identifier" (DOI). It is only in this way that the Crossref function and full-text downloads can be correctly tallied.

Categories of Contributions

1. Reviews and Minireviews

Reviews and Minireviews deal with topics of current interest in any of the areas covered by Chemistry—A European Journal. Rather than an assemblage 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 and Minireviews should be divided into numbered sections. Cross-references in the text refer to these section numbers. The review starts with a Lead-in or Abstract (ca. 800–1000 characters, no references). This text should not be a mere summary but rather should—together with a frontispiece picture—arouse the readers′ interest. The Introduction should primarily introduce the nonspecialist to the subject as clearly as possible. A Review or Minireview should conclude with a Summary and Outlook section, in which the achievements and new challenges for the subject are presented succinctly. In addition, a biographical sketch (500–700 characters) and a portrait-quality black-and-white photograph of each author, as well as a graphical suggestion for the first page of the Review or Minireview (frontispiece; 18 cm wide×18 cm high), a graphical abstract for the table of contents, and keywords should be submitted.

A Review should consist of a maximum of 40 pages (approximately 65000 characters) of main text, footnotes, literature citations, tables, and legends.

A Minireview should present current topics in a concise review style and consist of a maximum of 15 pages (approximately 25000 characters) of main text, footnotes, literature citations, tables, and legends. Minireviews offer the flexibility to treat topics at a time, and in a suitable manner, when a Review would still be premature or inappropriate.

2. Concepts

Concepts are short articles emphasizing 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 nonspecialist reader with a useful guide and the expert with a new angle on a familiar problem. Although Concept articles are generally written upon invitation of the Editor, unsolicited manuscripts are also welcome.

Concept articles may be organized as the author wishes, but should include a very short Abstract (400 characters; an additional version in the authors′ native language may also be included) that succinctly describes the concepts under discussion. A graphical suggestion for the first page of the Concept (frontispiece; 18 cm wide×18 cm high), a graphical abstract for the table of contents and keywords should also be provided. Articles should consist of around 10 single-spaced pages of text (approximately 17000 characters) including references, tables, and legends. The liberal use of schemes and figures is encouraged.

3. Communications and Full Papers

Communications and Full Papers present results of experimental or theoretical studies of general interest or great importance to the development of a specific area of research. A short text justifying why the manuscript should appear in Chemistry—A European Journal should be submitted. The essential findings presented in a Communication or Full Paper or significant parts of them may not already have appeared in print or in electronic online systems (for example, in online resources, in reviews, proceedings, or preprints). Contributions that are too specialized for the general readership of Chemistry—A European Journal will be returned to the authors without further external review (ca. 30%). All other Contributions are sent to two or more independent referees. Authors are welcome to suggest reviewers when they submit the manuscript. Detailed information that could be of importance to the referees, but that is unlikely to be of interest to the reader can be submitted as a separate file ("Additional Information") or as Supporting Information. The citation should be fair and informative but not excessive. Copies of cited publications not yet available publicly should be submitted along with the manuscript. Unpublished results and lectures should only be cited in exceptional circumstances.

Inclusive of all references, footnotes, and tables, a Communication should be no longer than approximately 15000 characters. Chemical formulae, figures, and schemes may also be added. Longer Communications will be accepted only if their quality warrants special consideration, and a written justification of their length is provided. Communications should not be divided into sections. However, experimental details can be summarized separately under the heading Experimental Section or Computational Methods. Additionally, we request that only the most essential parts of your experimental procedures be included here, the rest should be moved into the Supporting Information. Communications contain an Abstract, which should be brief (ca. 400 characters) and not too technical. The first paragraph of a Communication should give an introduction to enable readers unfamiliar with the subject to become acquainted with the importance of the results presented. In the final paragraph the results should be summarized succinctly, and one sentence should be devoted to their significance and, if appropriate, to remaining challenges.

A Communication returned to the author for revision should be returned to the Editorial Office within three weeks. If more time is needed the editor must be informed.

Full Papers, which generally contain an Experimental Section and/or Computational Methods, have no length restrictions. Additionally, we request that only the most essential parts of your experimental procedures be included here, the rest should be moved into the Supporting Information. Chemistry—A European Journal will not publish Full Papers that consist mainly of results reported in previous Communications with an added experimental section. Full Papers contain an Abstract, which should be brief (ca. 600–1000 characters) and not too technical, and an Introduction that includes relevant references. The presentation of Results and Discussion may be combined or kept separate. These sections may be further divided by subheadings.

4. Correspondence

Critical comments on publications in Chemistry—A European Journal 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.

5. Corrigenda

Scientifically incorrect or incomplete information in published articles should be corrected in a Corrigendum—which is as short as possible. Corrigenda are printed directly after the Table of Contents. We request that authors submit the Corrigendum electronically like any other article through Editorial Manager and that they cite the publication to be corrected as well as its "digital object identifier" (DOI).

Original Manuscript Submission

Manuscripts should be submitted by using our online submission service Editorial Manager ( or through our homepage at Please prepare two files: one containing the main manuscript (single-spaced text) with all graphics and tables integrated into the text; the other containing the Supporting Information (though not crystallographic CIF files, which should be deposited at the appropriate databank, such as the Cambridge Crystallographic Data Centre). Acceptable file formats are Microsoft Word, Rich Text Format, Postscript, and PDF.

MS Word templates for Concepts, Reviews, Minireviews, Communications, and Full Papers are available on our homepage in the section "Author Guidelines". Please only use these templates for the original submission of your contribution. Please prepare the final revised version of accepted contributions ("Submit Task" Production Material upload) as described in the Checklist.

Spelling can be British or American, but consistency should be maintained within a manuscript. Authors are asked to make their manuscripts suitable for a heterogeneous readership and to be considerate to our many readers for whom English is a foreign language—please use a simple, clear style, and avoid jargon. In some cases, it might be helpful for manuscripts to be checked by a native English speaker or other third parties, such as Wiley English Language Editing Services.

Authors can follow the progress of their manuscript on the Editorial Manager journal homepage using the "Author Login" (, which is created automatically upon initial registration.

Preparation of Production Data

If you submitted your original manuscript using Editorial Manager, you should upload your production data after acceptance. To do this you need to prepare an archive (preferably zip or rar); this should contain the text file and the separate graphics files, with a separate Supporting Information file, if applicable. You should then upload this through the "Submit task", production material upload within Editorial Manager. Further details will be provided on acceptance of the manuscript. In your cover letter, please inform us of the type of operating system (e.g., Windows, Mac) and the programs (with version) used to create the graphical material. Not all graphics programs are suitable for use by our Typesetters; please consult the Chemistry—A European Journal Checklist (available as a PDF file in the section "Author Guidelines"). If possible, the standard Symbol font should be used to create Greek letters, rather than special characters or graphics embedded in the text.

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. Basically, 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 please consult our "Instructions for LaTeX users" available on our homepage in the section "Author Guidelines".

Organization of Full Papers

We can process your manuscript faster if you lay it out as described below.

Title page: Title; authors′ names with academic titles, an asterisk denotes the correspondence author(s); affiliations of all the authors, including the full postal address and e-mail address of the correspondence author(s); series title, number, and reference to previous paper(s) in the series, if applicable; dedication, if applicable.

Abstract should be brief (ca. 600–1000 characters) and not too technical. An additional version of the abstract in the authors′ native language may also be supplied. When written in a non-Roman alphabet, this must be in a camera-ready form: the text must fit into a single column 8.5 cm wide; type size 2 mm (7 point); about 4 mm between lines (single-spaced).

Introduction should include relevant references.

Results and Discussion may be combined or kept separate and may be further divided by subheadings. This section should not be cluttered with technical details. Abbreviations and acronyms should be used sparingly and consistently. Where they first appear in the text, they should—apart from the most common ones, such as NMR, IR, and UV—be defined; you may prefer to explain large numbers of abbreviations and acronyms in a footnote on the first page.

Experimental Section should only contain the most essential parts of your experimental procedures; the rest should be moved into the Supporting Information. Taken together, the experimental data in the main manuscript and the Supporting Information should be given in sufficient detail to enable others to repeat your work. In theoretical papers, technical details such as computational methods should likewise be confined to an appropriately named section.

In so far as practical, authors should use a systematic name (IUPAC or Chemical Abstracts) for each title compound in the Experimental Section. Please do not use computer programs to generate elaborate systematic names or use long, multiline compound names; for the sake of clarity general descriptors such as compound 2, dendrimer 3, or alcohol 4 should be used.

Equipment and conditions used for the measurement of physical data should be described at the beginning of the Experimental Section. Quantities of reactants, solvents, etc. should be included in parentheses (e.g., triphenylstannyl chloride (0.964 g, 2.5 mmol) in toluene (20 mL)) rather than in the running text. Physical data should be quoted with decimal points and negative exponents (e.g., 25.8 JK−1mol−1). The identity of all new compounds must be fully characterized by appropriate analytical methods (e.g., NMR spectroscopy, X-ray crystal structure analysis, elemental analysis). The purity of all new compounds should be verified by elemental analysis, to an accuracy of within ±0.4%. In special cases, for instance, when the compound is unstable or not available in sufficient quantities for complete analysis, the exact relative molecular mass obtained from a high-resolution mass spectrum and a clean 13C NMR spectrum (as Supporting Information for inspection by the referees) should be supplied. These data should be given in the Supporting Information in the event that they exceed the scope of the Experimental Section.

Detailed presentation of physical data: Rf=0.38 (CHCl3/MeOH 9:1); m.p. 20°C; [α]D20=−13.5 (c=0.2 in acetone); 1H NMR (200 MHz, [D8]THF, 25°C, TMS): δ=1.33 (q, 3J(H,H)=8 Hz, 2H; CH2), 0.92 ppm (t, 3J(H,H)=8 Hz, 3H; CH3); 13C NMR (75 MHz, CDCl3, 25°C, TMS): δ=72.5 (CCH), 26.8 (s; CH3), 6.5 ppm (d, 1J(C,P)=156.9 Hz; CHP); IR (Nujol): \tilde \nu =1780, 1790 cm−1 (C[dbond ]O); UV/Vis (n-hexane): λmax (ε)=320 (5000), 270 nm (12000 mol−1dm3cm−1); MS (70 eV): m/z (%): 108 (20) [M+], 107 (60) [M+], 91 (100) [C7H7+]; elemental analysis calcd (%) for C20H32N2O5: C 63.14, H 8.48, N 7.36; found: C 62.88, H 8.41, N 7.44. Please give data in this order.

Computer-aided image enhancement is often unavoidable. However, such manipulation cannot result in data that are less relevant or unrepresentative being shown and/or genuine and significant signals being lost. A clear relationship must remain between the original data and the electronic images that result from those data. If an image has been electronically modified, the form of the modification shall be given in the figure caption. If computer-aided processing or modification of an image is a fundamental part of the experimental work, then the form that this processing takes must be clearly described in the Experimental Section.

Manuscripts containing animal experiments must include a statement that permission was obtained from the relevant national or local authorities. The institutional committees that have approved the experiments must be identified and the accreditation number of the laboratory or of the investigator given where applicable. If no such rules or permissions are in place in the country where the experiments were performed, then this must also be clearly stated. Manuscripts with experiments with human subjects or tissue samples from human subjects must contain a disclaimer in the Experimental Section to state that informed, signed consent was obtained from either the patient or next of kin.

Legends: Each figure and scheme should have a legend; in the revised manuscript these should be listed together at the end of the reference section of the text file rather than being included with the drawings in the graphics files.

Tables must have a brief title and should only be subdivided by three horizontal lines (head rule, neck rule, foot rule). Footnotes in tables are denoted [a], [b], [c], etc.

Illustrations (structural formulae, figures, schemes) should, if possible, be designed for reduction to a one-column format (8.6 cm wide). The maximum width is the two-column format (17.7 cm wide). For optimum reproduction, illustrations should be larger than the desired final size. We recommend: font for script, Helvetica; size of lettering, 3–3.5 mm; total maximum width, 14 cm (or 28 cm for two-column width) for 60% reduction.

Please also refer to our templates (currently ChemDraw only) available on our homepage in the section "Author Guidelines".

Italicize symbols of physical quantities, but not their units (e.g., T for temperature, in contrast to T for the unit Tesla, but K as unit; J, but Hz; a, but nm), stereochemical information (cis, Z, R, etc.), locants (N-methyl, tert-butyl) and symmetry (C2v). Chemical formulae should be numbered with boldface Arabic numerals (e.g., 1). Labels of axes are to be separated from their units by a slash (e.g., T/K) and the upper and right-hand lines joining the axes are to be removed. Abbreviations such as Me, Et, nBu, iPr, sBu, tBu and Ph (not φ) may be used in formulae. General substituents should be indicated by R1, R2 (not R2, which means 2R) or R, R′ (not R′). The spatial arrangement of the substituents should be indicated by hatched lines and solid wedges. A minus sign must be as long as the crossbar of a plus sign. Microscopy images (optical, electron, or scanning probe) should always contain a scale bar.

The publication of graphical material in color is expensive, and we request that part of the additional costs be carried by the author. As a result of the production process, the online and print versions of the manuscript must be identical. If color is deemed essential for the scientific understanding and the author does not have access to funds for publication costs, the journal may consider covering the additional costs.

Cover picture/frontispiece: We encourage authors to submit pictures for the cover page and for frontispieces. These pictures are chosen by the Editorial Staff prior to publication and part of the additional cost for color printing must be paid by the author; details will be provided after acceptance of the manuscript. In addition, the front cover page of each issue will be accompanied by a Cover Profile, which is a separate one-page article and includes photographs of the authors (or the groups) as well as questions related to the research.

Graphical abstract: A short text (no more than 450 characters) with an eye-catching headline for the table of contents should be included as the last page and saved as part of the main text. It should tempt browsers to read the article, and so need not summarize the entire paper. Repetition or paraphrasing of the title and presentation of experimental details should be avoided. Graphics (formulae, part of a figure) should be kept small (final size preferably 5.5 mm wide; font size 6–7 point) and must be explicitly referred to in the text. Color graphics for the table of contents are free. Templates indicating the appropriate sizes for table of contents graphics are available on our homepage in the section "Author Guidelines".

Crystal Structure Analysis

Authors must deposit their data before submitting their manuscripts or update data already available, so that referees can retrieve the information directly from the database. Please use the free online Checkcif service provided by the International Union of Crystallography and submit the Checkcif report along with your manuscript. Please ensure that the data deposited with the database are identical to those in the manuscript.

Crystallographic data should not be sent as Supporting Information but should be deposited with either the Cambridge Crystallographic Data Centre for organic and organometallic compounds or with the Fachinformationszentrum Karlsruhe for inorganic compounds, elements, metals, and minerals.

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, 2θmax, 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 will not be reproduced when it merely serves to confirm the structure of a synthetic intermediate.

For organic and organometallic compounds: Send your data including author and journal details in CIF format to the Cambridge Crystallographic Data Centre (CCDC, 12 Union Road, Cambridge CB2 1EZ (UK); tel: (+44)1223-336-408; fax: (+44)1223-336-033; e-mail:; see also WWW: The data will be assigned a registry number, which should be included with the following standard text in the manuscript: "CCDC-… contain(s) the supplementary crystallographic data for this paper. These data can be obtained free of charge from The Cambridge Crystallographic Data Centre via"

For inorganic compounds: The Fachinformationszentrum Karlsruhe only accepts data deposited in electronic form (in CIF format). Send the data by e-mail (or on disk) to FIZ, 76344 Eggenstein-Leopoldshafen (Germany); tel: (+49)7247-808-205; fax: (+49)7247-808-666; e-mail:; WWW: under "Products". You will be given a CSD number, which should be included with the following standard text in the manuscript: "Further details of the crystal structure investigation(s) can be obtained from the Fachinformationszentrum Karlsruhe, 76344 Eggenstein-Leopoldshafen, Germany (fax: (+49)7247-808-666; e-mail: on quoting the depository number CSD-. . ."

Supporting Information

All material that is intended to be published only online as Supporting Information should be presented succinctly (in English). This material undergoes the peer review process and must therefore be included with the original submission. The author bears full responsibility for the content of the Supporting Information. Color and animated multimedia applications are welcome and published online at no cost to the author or reader. Please refer to such applications in the article itself where appropriate (see the Supporting Information).

In addition, the standard text:

Supporting information for this article is available on the WWW under should be added as a footnote after the addresses. Supporting Information should not include crystallographic data that are available from CCDC or FIZ.

To submit multimedia files that exceed 5 MB in size, please save them on your web server, but do not link to them. Send us the URL so we can download the files and make them available to referees and, if accepted, to readers. Please use suitable compression technology to avoid exceedingly large movie files (>10 MB) for the benefit of referees′ and readers′ bandwidth and storage capacity. Also, please make sure that your movies are saved in a common format (such as MPEG, AVI, QuickTime, GIF) that can be played on at least two different computer platforms (out of Windows/MacOS/Linux). Smaller files can simply be sent as an e-mail attachment.

Basic Keyword List

An interjournal online browsing facility has been developed for the readers of the Wiley-VCH journals Advanced Energy Materials, Advanced Engineering Materials, Advanced Functional Materials, Advanced Healthcare Materials, Advanced Materials, Advanced Materials Interfaces, Advanced Optical Materials, Advanced Synthesis & Catalysis, Angewandte Chemie International Edition, Asian Journal of Organic Chemistry, ChemBioChem, ChemCatChem, ChemElectroChem, Chemistry—A European Journal, Chemistry—An Asian Journal, ChemistryOpen, ChemMedChem, ChemPhysChem, ChemPlusChem, ChemSusChem, European Journal of Inorganic Chemistry, European Journal of Organic Chemistry, Macromolecular Rapid Communications, Particle & Particle Systems Characterization, Small, and ZAAC. This enables you to move between lists of thematically related contributions by a mouse click.

We have compiled a common keyword catalogue that is available in the "Author Guidelines" section. To assist you in finding keywords, they are listed according to category. As with all such records, a few guidelines facilitate its use, and these are briefly explained below:

At least two of the maximum of five keywords assigned to an article must come from this list.
In the German edition of Angewandte Chemie, the German equivalent of these terms will be used.
Named reactions will be incorporated only in exceptional cases. Generally the reaction type is selected instead. For example, Diels–Alder reactions will be found under "cycloadditions" and Claisen rearrangements under "rearrangement".
Heteroanalogues of compounds are mainly classified under the C variants, for example, (hetero)cumulenes, (hetero)dienes. A few aza and phospha derivatives are exceptions.
Compounds with inorganic components that are central to the article are listed under the element, for example, iron complexes under "iron" and, if appropriate, the ligand type. Some group names such as "alkali metals" exist alongside the names of important members of the group, for example, "lithium". In such cases the group name is used for these members only when comparative studies are described. The members that do not appear separately are also categorized under the group name.
A keyword in the form "N ligand" is only chosen if a considerable portion of the paper deals with the coordination of any ligand that coordinates through the atom concerned (in the example, nitrogen).
Spectroscopic methods are assigned as keywords only if the article is about the method itself or if the spectroscopic technique has made an important contribution to the problem under investigation.
"Structure elucidation" is intended only if the crux of the paper is a structural elucidation or if a combination of several spectroscopic techniques were needed for conclusive solution of the structure.
An attempt has been made to avoid synonyms and to select more general concepts rather than specialized terms. Thus the term "double-decker complexes" is excluded in favor of "sandwich complexes". See also points 3 and 4 in these guidelines.
Enzymes should be assigned to one of the six main enzyme classes (hydrolases, isomerases, ligases, lyases, oxidoreductases, transferases).

This list will be a "living" catalogue to be flexible enough to absorb the new developments in chemistry. We therefore welcome all suggestions from our readers and authors that might improve its user-friendliness. The current version may be found on the internet under the following address:
