1. General Information

Chemistry—An Asian Journal was founded by the Chemical Society of Japan, the Chinese Chemical Society, the Chemical Research Society of India, the Korean Chemical Society, and Wiley-VCH. It is now a journal of the major chemical societies of Australia (RACI), China (CCS), Hong Kong (HKCS), India (CRSI), Indonesia (HKI), Japan (CSJ), Korea (KCS), Malaysia (IKM), New Zealand (NZIC), Singapore (SNIC), Taiwan (CSLT), Thailand (CST), and Vietnam (CSV), which together comprise the Asian Chemical Editorial Society (ACES). As a sister journal of Angewandte Chemie and Chemistry—A European Journal, it is supported by the German Chemical Society (GDCh), ChemPubSoc Europe (CPSE), and the Federation of Asian Chemical Societies (FACS). It is also a sister journal to the ACES journals Asian Journal of Organic Chemistry and ChemNanoMat. All general formal aspects of manuscript styling are the same within this family of journals, which should be beneficial for our authors.

Chemistry—An Asian Journal is published twice monthly and contains papers from all fields of chemistry. All contributions are evaluated with the help of Editorial Board members and they are subject to peer review. Please indicate which Editorial Board member(s) is (are), in your opinion, most suitable in terms of expertise to evaluate your manuscript. Contributions that are not suitable for Chemistry—An Asian Journal will be returned to the authors without external review. All other contributions are sent to two or more independent referees. Authors are encouraged to suggest referees upon submission.

Contributions should be in English; submission of an abstract in the language of the authors is encouraged in addition to the abstract in English. The correspondence author will receive page proofs as compressed PDF files and, after publication of the article, a PDF reprint file restricted to 25 printouts. There are no page charges for articles published in Chemistry—An Asian Journal, and color figures are reproduced free of charge.

Chemistry—An Asian Journal does not publish manuscripts that have already appeared in print or electronically. 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—An Asian Journal. If the manuscript is a revised or extended version of a manuscript previously rejected by Chemistry—An Asian 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 Ethical Guidelines for Publication in Journals and Reviews issued by the European Association of Chemical and Molecular Sciences are followed and applied by the editors of Chemistry—An Asian Journal. In particular, authors should reveal all sources of funding for the work presented in the manuscript and should declare any conflict of interest. When dealing with cases that result from possible violations of these guidelines, the journal follows procedures established by the Commission on Publication Ethics (COPE). Please note that all submitted manuscripts are subject to plagiarism checks.

The journal may examine the prior history of manuscripts submitted to, but not accepted in, other Wiley-VCH journals, including (but not limited to) Angewandte Chemie (International Edition), Chemistry—A European Journal, and Advanced Materials. Authors are encouraged to disclose such prior submissions in their cover letter and to address any reviewer comments, when applicable. Please note that submissions to Chemistry—An Asian Journal may not be under evaluation at any other journal at the time of submission.

In the event of acceptance, papers can be published online as Accepted Articles prior to editing and proofing. Please indicate if you wish to have your paper published online as an Accepted Article by ticking or unticking the relevant box in the submission system when submitting your production material. If you wish to have your article published as soon as possible online as an Accepted Article, the final version of the manuscript must be submitted in the appropriate template. Please also ensure that the order of authors and title in the submission system match those in the final version of the manuscript before submitting the production material. Corrections will be incorporated only through the editing and proofing process.

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—An Asian Journal offers such a service. All of the information about this topic is found in the Open Access section on our homepage. Chemistry—An Asian 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 in the unedited and not proofread form after acceptance. In general, we recommend that authors link to their Chemistry—An Asian 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.

Queries regarding manuscripts should be sent to The official Chemical Abstracts Service Source Index (CASSI) abbreviation for Chemistry—An Asian Journal is "Chem. Asian J.".

2. Categories of Contributions

2.1. Focus Reviews

Focus Reviews are critical but balanced and scholarly surveys of recent developments in a focused research field; they are broader than personal accounts but not as comprehensive as reviews. Although Focus Reviews should be recognized as scholarly by specialists in the field, they should be written with a view to informing chemists in general. Thus, Focus Reviews (up to 25000 characters) should avoid excessive jargon and too much technical detail. Focus Reviews should contain ample illustrations (figures, formulae, schemes, tables). References are limited to 100 (citations should be selective). Focus Reviews start with a lead-in (600–1000 characters, no references), which together with the frontispiece (18 cm×18 cm) should arouse the interest of the reader. The article itself is then structured according to the following themes: 1) Introduction; 2) Body with several chapters (numbered headings and subheadings); 3) Conclusions and perspectives. In addition, a biographical sketch (maximum length 560 characters) and a portrait-quality color photograph of the author(s) should be submitted. Focus Reviews are mostly written upon invitation; however, independent submissions are welcome if they are written according to the guidelines above. For formal aspects of manuscript preparation, please see Section 5 (Organization of Full Papers) below, which applies as far as the general aspects (figures, references, etc.) are concerned.

2.2. Essays

In Essays (up to 20000 characters) themes from every aspect of chemistry, including the philosophy or history of science, are addressed freely. Use of unpublished results from original research should be extremely limited. Primarily, known topics should be discussed illuminatingly and critically from a new vantage point, and they should be suitably illustrated. In addition, a biographical sketch (maximum length 560 characters) and a portrait-quality color photograph of the author(s) should be submitted.

2.3. 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—An Asian 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 electronically (including, for example, in online resources, in reviews, proceedings, or preprints). Contributions that are too specialized for the general readership of Chemistry—An Asian Journal will be returned to the authors without further external review. All other contributions are sent to two or more independent referees; authors are welcome to suggest referees. On the basis of the recommendations of the referees and of an Editorial Board member, the Editor will make a decision on whether to accept a contribution.

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 Supporting Information. Supporting Information is required for Full Papers and Communications. Please see Section 5 for experimental requirements. Only articles that have already been published in a scientific journal should be cited, although authors are encouraged to use the digital object identifier (DOI) to cite papers available online for which page numbers have not yet been assigned. 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.

Each Communication and Full Paper contains an Abstract. In this abstract, the motivation for the work, the methods applied, the results, and the conclusions drawn should be presented (maximum 1000 characters). When you write the abstract, please keep the following aspects in mind: 1) The abstract should awaken the curiosity of as many readers as possible; 2) The abstract should reflect the content of the paper, and the text should contain several keywords to aid finding the paper online; 3) The abstract should refer neither to graphical elements or tables in the paper nor to references, as the abstract will be found independently, for example in databases; and 4) Please restrict the use of abbreviations to a minimum.

A Communication should be no longer than approximately 15000 characters, including all references, footnotes, and tables. Chemical formulae, figures, and schemes may also be added. Communications should not be divided into sections; however, experimental or computational details can be summarized separately under the heading Experimental Section or Computational Methods. 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.

Full Papers, which generally contain an Experimental Section and/or Computational Methods, have no length restrictions. However, the editorial office requests that space be used thoughtfully and economically (e.g., additional experimental data for derivatives and intermediates can be placed in the Supporting Information). Chemistry—An Asian Journal will not publish Full Papers that consist mainly of results reported in previous Communications with an added experimental section. Full Papers contain 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.

2.4. Correspondence

Comments on publications in Chemistry—An Asian 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. This reply will be sent to the author of the Correspondence.

2.5. Corrigenda

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 through Editorial Manager and that they cite the publication to be corrected as well as its digital object identifier (DOI).

3. Submission of the Original Manuscript

Authors are requested to submit their manuscripts through 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 at the appropriate position; 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). Follow the instructions on the online submission website to upload these files. If you experience any problems please make use of the contact form at this site.

MS Word templates for Focus Reviews, Essays, Communications, and Full Papers are available on our homepage in the section "Author Guidelines". Please use these templates for the submission of your contribution. Details for the preparation of the final revised version of accepted contributions ("Production Data") are provided in the checklist that is attached to the acceptance letter.

American spelling should be used throughout the manuscript. Authors are asked to make their manuscripts suitable for a heterogeneous readership—please use a simple, clear style, and avoid jargon. In some cases, it might be helpful for manuscripts to be checked by a third party, such as Wiley English Language Editing Services, for correct language usage before submission.

We encourage all authors to provide an ORCID identifier for each coauthor. ORCID is a registry that provides researchers with a unique digital identifier. Some funding agencies recommend or even require the inclusion of ORCID IDs in all published articles, and authors should consult their funding agency guidelines for details. Registration is easy and free; for further information, see

Authors can follow the progress of their manuscript on their personal homepage (, which is created automatically upon initial registration. This homepage can be used to store all versions of a submitted paper and to upload the necessary production data after acceptance (see below), and completed referee reports are also archived here.

4. Submission of the Production Data (for Accepted Manuscripts)

If you submitted your original manuscript through Editorial Manager, you should upload your production data after acceptance through your homepage. These data should include the text file and the separate graphics files (one for each figure or scheme) with a separate file for the Supporting Information, if applicable, and a separate file for any abstract using a non-Roman alphabet. You should then upload these files through the "Submit task", production material upload within Editorial Manager. Further details will be provided upon acceptance of the manuscript. Not all graphics programs are suitable for use by our production team; details will be provided after a manuscript has been accepted. If possible, the standard Symbol font should be used to create Greek letters, rather than special characters or graphics embedded in the text. All structural formulae should be provided as ChemDraw (.cdx) files.

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" on our Journal homepage ("Author Guidelines").

5. 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); dedication, if applicable.

Abstract should be brief (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 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.

If 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 1H and 13C NMR spectra of all key intermediates and all final products should be included in the Supporting Information. 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.

Detailed presentation of physical data should be given in the following order: Rf=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, 25°C, TMS): δ=7.64–7.48 (m, 6H; Ar-H), 1.33 (q, 3J(H,H)=8 Hz, 2H; CH2), 0.92 (t, 3J(H,H)=8 Hz, 3H; CH3), 0.79 ppm (s, 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); fluorescence (CH2Cl2): λex=435.5 nm; λem=659, 726 nm; MS (70 eV): m/z (%): 108 (20) [M+], 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.

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 must 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 a one-column format (8.5 cm wide) with text 1.5 to 2 mm high (about 7 point font). Please note that Chemistry—An Asian Journal does not use charts; these should be converted into structural formulae or schemes. The maximum width is the two-column format (17.5 cm wide). Color figures are reproduced free of charge. Authors are encouraged to use color to enhance Figures and Schemes.

All graphical material containing structural formulae should be provided as ChemDraw (.cdx) files. Please also refer to the templates on our Journal homepage "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.

Cover picture/frontispiece: We encourage authors to submit pictures for the cover page and for frontispieces.

Graphical abstract: A short text (approximately 350 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. A graphic should be provided that is kept small with minimum detail, as the maximum final size is either approximately 5.5×5.0 cm or 11.5×2.0 cm.

Keywords: A maximum of five keywords should be given in alphabetical order. At least two keywords from the core keyword list (see section on Keywords below) should be included to aid online searching.

6. 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 at 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 as a plain text ASCII file by email 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 to FIZ, 76344 Eggenstein-Leopoldshafen (Germany); tel: (+49)7247-808-205; fax: (+49)7247-808-666;; 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-. . ."

7. 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.

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.

Color, 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. To submit large multimedia files, 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).

8. 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 Wiley-VCH journals Advanced Functional Materials, Advanced Materials, Advanced Synthesis & Catalysis, Angewandte Chemie International Edition, Asian Journal of Organic Chemistry, ChemBioChem, ChemCatChem, Chemistry—A European Journal, Chemistry—An Asian Journal, ChemCatChem, ChemMedChem, ChemNanoMat, ChemPhysChem, ChemSusChem, European Journal of Inorganic Chemistry, European Journal of Organic Chemistry, Macromolecular Rapid Communications, Small, and ZAAC.

We have compiled a common keyword catalogue that is available online at This catalogue is subdivided to facilitate the search for keywords but can also be searched as a complete list. Some of the keywords are used in more than one area. 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.


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 instance, 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 2 and 3 in these guidelines.


Enzymes should be assigned to one of the six main enzyme classes (hydrolases, isomerases, ligases, lyases, oxidoreductases, transferases).

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