“In press” references should include the Digital Object Identifier (DOI) assigned by the potential publisher.
TABLES AND ARTWORK
The tables and graphics (illustrations) should be inserted in the manuscript file after the References section. Do not upload tables and graphics that are to be published with the manuscript as Supporting Information files.
Tables and figures should be carefully designed to maximize presentation and
comprehension of the experimental data with superfluous information excluded. Useful information not directly relevant to the discussion may be included under Supporting Information.
Tables. Tables may be created using a word processor’s text mode or table format feature. The table format feature is preferred. Ensure each data entry is in its own table cell. Lower case should be used for all table entries unless a capital letter is required. If the text mode is used, separate columns with a single tab and use a line feed (enter) at the end of each row.
Tables should be numbered consecutively with Arabic numerals and should be grouped after the figure captions. Footnotes in tables should be given letter designations and be cited in the table by italic superscript letters. The sequence of letters should proceed by row rather than by column. Each table should be provided with 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 type area of the journal page (17.8 × 25.4 cm), and the column width (8.5 cm), and to make tables conform to the limitations of these dimensions. Arrangements that leave many columns partially filled or that contain much blank space should be avoided. Conversely, arrangements that include >20 columns should be broken into two tables if possible. If significance of values is to be indicated, use a lower case letter, on line, one space after the value.
Figures and Artwork. The preferred submission procedure is to embed graphic files in a Word document. It may help to print the manuscript on a laser printer to ensure all artwork is clear and legible. Artwork should be sequentially numbered using Arabic numbers. Schemes and charts may have titles and footnotes; figures should have captions. Insert the captions following the References and the graphics after the Tables.
Additional acceptable file formats are TIFF, PDF, EPS (vector artwork), or CDX (ChemDraw file). If submitting individual graphic files in addition to their being embedded in a Word document, ensure the files are named according to graphic function (i.e., Scheme 1, Figure 2, Chart 3), not the scientific name. Labeling of all figure parts should be present, and the parts should be assembled into a single graphic. For EPX files, ensure that all fonts are converted to outlines or embedded in the graphic file. The document setting should be in RGB mode. Note: Although EPS files are accepted, the vector-based graphics will be rasterized for production. Please see below for TIFF file production resolutions.
TIFF files (either embedded in a Word document or submitted as individual files) should have the following resolution requirements: black and white line art, 1200 dpi; grayscale art (a
monochromatic image containing shades of gray), 600 dpi; color art (RGB color mode), 300 dpi. The RGB and resolution requirements are essential for producing high-quality graphics within the published paper. Graphics submitted in CMYK or at lower resolution may be used; however, the colors may not be consistent. Graphics of poor quality may not be able to be improved.

Most graphic programs provide an option for changing the resolution when images are saved. Best practice is to save the graphic file at the final resolution and size using the program used to create the graphic.
For bar charts, bars with hatching patterns generally reproduce well. Bars that range in shading from light to dark gray to black can usually be reproduced successfully, although we do not recommend any more that two shades of gray. A legend needs to be included within the figure itself rather than the patterns or shades included in the caption.
For manuscripts containing gel patterns, use of a high-resolution digital scanner is recommended. Only high-quality original, unaltered digital reproductions will allow reviewers to correctly verify the experimental results. For an example of gel patterns see J. Agric. Food Chem. 2004, 52, 5717–5723, Figures 2 and 3.
Only readable and accurately represented images are acceptable; the Editors reserve the option to reject images that do not satisfactorily support points made in the manuscript or that are not of satisfactory quality for publication.
The quality of the illustrations published in the Journal largely depends on the quality of the originals provided. Figures cannot be modified or enhanced by the journal production staff. Contrast is important. Each figure or photograph should be properly labeled.
Graphics should be sized at the final production size when possible. Single-column graphics are preferred and can be sized up to 240 points (3.33 in.). Double-column graphics must be sized between 300 and 504 points (4.167 in. and 7 in.). All graphics have a maximum depth of 660 points (9.167 in.) including the caption (please allow 12 points for each line of caption text). Consistently sizing letters and labels in graphics throughout the manuscript will help to ensure consistent graphic presentation for publication. Lettering should be no smaller than 4.5 points. (Helvetica or Arial type works well for lettering.) Lines should be no thinner than 0.5 point. Lettering and lines should be of uniform density. Avoid the use of very large and very small lettering within the same figure.
If artwork that must be reduced will be submitted, use larger lettering and thicker lines so that, when reduced, the artwork meets the above-mentioned parameters.
Avoid using complex textures and shading to achieve a three-dimensional effect. To show a pattern, choose a simple crosshatch design.
Color illustrations should be submitted only if they are essential for clarity of communication. Reproduction of color illustrations will be provided at no cost to the author. Do not submit color prints to be printed in black and white.
Structural Formulas. Structural formulas should be included for all new chemicals and for existing chemicals for which chemical nomenclature and/or trivial names do not convey the structure adequately. Structural formulas are valuable in expressing concisely the precise nature of the compounds under discussion and revealing the essence of the subject to readers unfamiliar with the topic, without their necessary recourse to reference materials. The use of chemical names without accompanying structures may cause readers to overlook the significance of the paper.
Structures should be produced with the use of a drawing program such as ChemDraw. Structure drawing preferences (preset in the ACS Stylesheet in ChemDraw) are as follows:
as drawing settings select…
chain angle
120o
12
bond spacing fixed length bold width line width margin width hash spacing as text settings select…
font size under preferences choose…
units
tolerances under page setup choose…
paper scale
18% of width
14.4 points (0.508 cm, 0.2 in.) 2.0 points (0.071 cm, 0.0278 in.) 0.6 point (0.021 cm, 0.0084 in.) 1.6 points (0.056 cm, 0.0222 in.) 2.5 points (0.088 cm, 0.0347 in.)
Arial or Helvetica 10 points points 3 pixels US Letter 100%
Using the ChemDraw ruler or appropriate margin settings, create structure blocks, schemes, and equations having maximum widths of 11.3 cm (one-column format) or 23.6 cm (two-column format). Note: if the foregoing preferences are selected as cm values, the ChemDraw ruler is calibrated in cm. Also note that a standard sheet of paper is only 21.6 cm wide, so all graphics submitted in two-column format must be prepared and printed in landscape mode. Use boldface type for compound numbers but not for atom labels or captions.
Authors using other drawing packages should, as far as possible, modify their program’s parameters to reflect the above guidelines.

TABLE OF CONTENTS GRAPHICS
Authors of research articles, perspectives, and reviews are required to include a suitable graphic for publication in the table of contents (TOC) in the Web edition of the Journal. Submission of this graphic is mandatory. This graphic should capture the reader’s attention and, in conjunction with the manuscript’s title, give the reader a quick visual impression of the type of chemistry described. Structures should be constructed as specified under Structural Formulas above. The TOC graphic may be up to 3.25 in. (8.5 cm) wide and 1.75 in. (4.75 cm) tall. (See detailed instructions at the Paragon Plus Web site.) Text should be limited to labels for compounds, reaction arrows, and figures. The use of color to enhance the scientific value is encouraged. The TOC graphic should be inserted on a separate page at the end of the manuscript file. A guide to TOC graphics is available here:
(http://pubs.acs.org/paragonplus/submission/toc_abstract_graphics_guidelines.pdf).
SUPPORTING INFORMATION
Extensive tables, graphs, spectra, calculations, and other material beyond a modest content in the published paper may be included in the Web edition of the Journal. These will not be part of the published article but can be accessed separately on the Web by readers.
Supporting Information must be submitted at the same time as the manuscript and uploaded separately to the ACS Paragon Plus environment. A list of acceptable file types is available on the Web. All Supporting Information files of the same type should be prepared as a single file
13
(rather than submitting a series of files containing individual images or structures). For example, all Supporting Information available as PDF files should be contained in one PDF file. The material should be described in a paragraph inserted between the Acknowledgment and the References sections, using the following format: “Supporting Information Available:
Description. This material is available free of charge via the Internet at http://pubs.acs.org.” Components of the Supporting Information should be clearly labeled with all necessary figure captions and table titles and footnotes.
DO NOT UPLOAD FIGURES AND TABLES THAT ARE TO BE PUBLISHED IN THE ARTICLE INTO THE SUPPORTING INFORMATION FILE. Figures and tables that will appear in the published article are to be inserted in the manuscript directly after the References section.
CONFLICT OF INTEREST
A statement describing any financial conflicts of interest or lack thereof is published with each manuscript. During the submission process, the corresponding author must provide this
statement on behalf of all authors of the manuscript. The statement should describe all potential sources of bias, including affiliations, funding sources, and financial or management
relationships, that may constitute conflicts of interest (please see the Ethical Guidelines). The statement will be published in the final article. If no conflict of interest is declared, the following statement will be published in the article: “The authors declare no competing financial interest.”
