Information for authors

Chinese Chemical Letters (CCL) (ISSN 1001-8417) was founded in July 1990. The journal publishes preliminary accounts in the whole field of chemistry, including inorganic chemistry, organic chemistry, analytical chemistry, physical chemistry, polymer chemistry, applied chemistry, etc.,satisfying a real and urgent need for the dissemination of research results,especially hot topics. The journal does not accept articles previously published or scheduled to be published. To verify originality, your article may be checked by the originality detection service CrossCheck.

The types of manuscripts include Perspective, Highlight,Communication and Review. The experimental evidence necessary to support your manuscript should be supplied for the referees and eventual publication as Electronic Supplementary Information. The reviews are written by leading scientists within their field and summarized recent work from a personal perspective. They cover many exciting and innovative fields and are of general interest to all chemists.

Submissio n

The contents of papers are the sole responsibility of the authors, and publication shall not imply the concurrence of the Editors or Publisher.

Authors should submit their manuscripts via the online submission page of this journal at http://ees.elsevier.com/cclet. Authors will be guided stepwise through the creation and uploading of the various files.The system automatically converts source files to a single Adobe Acrobat PDF version of the article, which is used in the peer review process.Please note that even though manuscript source files are converted to PDF at submission for the review process, these source files are needed for further processing after acceptance. All correspondence, including notification of the editor’s decision and requests for revision, takes place by e-mail and via the author’s home page.

The following items should be submitted via the online submission page:

1. Cover letter:highlighting the novelty, significance, and urgency of the submitted work, which merits rapid publication and providing details of other relevant information, e.g., submitted or in press manuscripts.

2. Graphical abstractfor the contents list (submitted as a separate document).

3. Manuscript.

Authors are also suggested to supply the names of two suitable referees for their manuscript upon submission. Authors are also permitted to provide the names of scientists that they would prefer not to review their manuscript. If the names of non-preferred reviewers are provided,authors are requested to provide a brief note stating why these reviewers should not be used.

Copyright

Upon acceptance of an article, authors will be asked to complete a ‘Copyright Transfer Statement’. An e-mail will be sent to the corresponding author confirming receipt of the manuscript together with a‘Copyright Transfer Statement’ form. Subscribers may reproduce tables of contents or prepare lists of articles including abstracts for internal circulation within their institutions. Permission of the Publisher is required for resale or distribution outside the institution and for all other derivative works, including compilations and translations. If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article. Note that all authors should sign the Statement and publication of the accepted manuscript in an online issue is suspended until the Statement is received.

Graphical abstract

Graphical abstract is mandatory for our journal. It should summarize the contents of the article in a concise, pictorial form designed to capture the attention of a wide readership online. Authors must provide images that clearly represent the work described in the article. Graphical abstract, including title,authors, affiliations, the graph, and short abstract in one or two sentences,should be submitted as a separate file in the online submission system.

Main text

Text should be subdivided in the simplest possible way consistent with clarity. Ensure that all tables, figures, and schemes are cited in the text in numerical order. The preferred position for chemical structures should be indicated. Trade names should have an initial capital letter. All measurements and data should be given in SI units where possible, or in other internationally accepted units. Abbreviations should be used consistently throughout the text, and all non-standard abbreviations should be defined on first usage. Authors are requested to draw attention to hazardous materials or procedures by adding the word CAUTION followed by a brief descriptive phrase and literature references if appropriate.

Title.Concise and informative. Titles are often used in informationretrieval systems. Avoid abbreviations and formulae where possible.

Author names and affi liations.The authors’ names are listed with the given name first and surname last (capitalizing the first letter, the best is use the spelling they are commonly using in scientific papers). Present the authors’ affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author’s name and in front of the appropriate address.Provide the full postal address of each affiliation, including the country name.

Corresponding author.Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication.Ensure that the e-mail address is provided and contact details must be kept up to date by the corresponding author.

Changes to authorship. Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editor. To request such a change, the Editor must receive the following from the corresponding author: (a) the reason for the change in author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.

Abstract. Authors must include a short abstract of approximately that states briefly the purpose of the research, the principal results, and major conclusion(s).

Introduction. State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Experimental. Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference,only relevant modifications should be described. Other unimportant information can be deposited in Supporting information which will be available in online version.

Results and discussion. Results should be clear and concise. Discussion should explore the significance of the results of the work, not repeat them.A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

Conclusions. The main conclusions of the study may be presented in a short Conclusions paragraph, which may stand alone or form a subsection of a Discussion or Results and Discussion section.

Please note:All these sections need to be combined in a single untitled section and only hold essential information, others can be put in Supporting files. In general, communication should not more than four printed pages.

Artwork. Figures, schemes, and equations must be cited in the text and numbered in order of appearance with Arabic numerals. All graphics (including chemical structures) must be provided at the actual size that they are to appear (single-column width is 8.4 cm, double-column width is 17.7 cm). Please ensure that all illustrations within a paper are consistent in type, quality, and size. Legends should be included as part of the graphic. Color figures may be printed in the journal, provided that the editor considers the color necessary to convey scientific information.Ensure that all figures cited in reviews are permitted by the authority.

Tables. All tables should be cited in the text, and numbered in order of appearance with Arabic numerals. All table columns should have a brief explanatory heading and, where appropriate, units of measurement. Vertical lines should not be used. Footnotes to tables should be typed below the table and should be referred to by superscript letters.Each table should have a descriptive heading, which, together with the individual column headings, should make the table, as nearly as possible,self-explanatory. In setting up tabulations, authors are requested to keep in mind the column widths (8.4 cm and 17.7 cm), and to make the table conform to the limitations of these dimensions.

Acknowledgements

An acknowledgement section may be included. It should be placed after the manuscript text and before the references.
