Is Your Paper Ready for Chemical Communications? The 5-Page Speed Test

ChemComm doesn't require your paper to rewrite a textbook chapter. It requires your paper to report something genuinely new. That distinction sets a lower bar than JACS or Angewandte while still filtering out submissions at the desk stage.

The editorial screen runs on three questions:

Is there a new finding here? Not a new application of an old method. Not the same reaction on a different substrate. A new finding, a new reaction, a new property of a known material, an unexpected selectivity, or a mechanistic insight that changes how people think about a known process. The bar isn't "field-redefining." It's "this wasn't known before and it's interesting."

Will chemists outside this subspecialty care? ChemComm covers all of chemistry: organic, inorganic, physical, analytical, biological, materials, computational. But editors want papers that would make a synthetic chemist pause while flipping past an inorganic paper, or a materials researcher bookmark a catalysis result. If your paper is only interesting to the 30 people who work on your exact ligand system, it won't clear the desk.

Can this story fit the format? Communications now have a 5-page total limit (announced by RSC on 18 November 2025) with 3.5 pages for title, authors, and main text through conclusions. The remaining 1.5 pages cover references, acknowledgements, and author statements. If your result needs 8 figures and 6,000 words, ChemComm is the wrong journal. Papers that feel like squeezed full articles get returned, even when the science is fine.

ChemComm's 3.5-page main-text limit is both its greatest strength and the thing that trips up most authors. All detailed experimental procedures, characterization data, and supplementary figures go into the Electronic Supplementary Information (ESI). Here's where people go wrong.

Cramming a full paper into Communication format. If you've got five figures, three tables, and a 4-page introduction draft, you don't have a Communication. ChemComm papers typically have 3-4 figures and zero or one tables in the main text. Everything else goes in the ESI.

Skimping on the ESI. The main text should be lean, but the ESI shouldn't be an afterthought. Reviewers will check NMR assignments, crystal structures, kinetic data, and control experiments. A thin ESI signals that the work itself is thin, and that's a rejection trigger.

Writing a literature review as your introduction. You don't have space. Your opening paragraph needs to state the problem and your contribution within the first 3-4 sentences. Cut the "considerable interest in recent years" preamble. State what's missing, say what you did about it, move on.

Overloading figures. A 6-panel figure with tiny fonts and dense annotations tells the editor you're trying to bypass the page limit through visual compression. Each figure should make one clear point.

What works

First reports of unexpected reactivity. A reaction that shouldn't work based on established theory, but does. Substrate scope may be limited, mechanism not fully resolved, but the result itself is surprising. You don't need the complete story, you need the interesting beginning.

Catalytic systems with a mechanistic twist. Not "material A does reaction B faster than material C," but "material A does reaction B through a mechanism nobody predicted, and here's the spectroscopic evidence." The mechanism lifts it from incremental improvement to publishable finding.

Proof-of-concept with clear implications. A new approach that works, even if optimization is still needed. ChemComm readers understand they're reading preliminary reports, not finished stories.

Supramolecular results with structural characterization. ChemComm has a strong tradition here. Well-characterized cages, rotaxanes, or host-guest systems with clear binding data tend to do well.

What doesn't work

Pure optimization studies. You screened 40 solvents and found the best one. Useful data, but no new finding, just a parameter survey.

Materials papers without molecular-level insight. A new MOF with high BET surface area and clean SEM but no explanation for why it outperforms 500 related structures reads as descriptive. Editors are trained to spot this.

Methods papers for specialty audiences. A new analytical method for trace metal detection belongs in Analyst or JAAS (both RSC). Editors will often suggest transfer to a sister journal rather than send the paper for review.

Compressed full articles. If your abstract mentions six different findings, you have an article, not a Communication.

ChemComm uses single-anonymised review by default, and double-anonymised review is an opt-in at submission; RSC publishes no reviewer count. RSC says researchers typically receive a first decision on a peer-reviewed manuscript within three weeks of submission, and lists medians of 16 days (all decisions) and 22 days (peer reviewed). One thing worth knowing: editors frequently use "revise and resubmit" for papers that are close but not quite there. If the science is sound but the novelty claim is overstated, you'll often get a chance to revise. This is different from Angewandte, where desk rejections tend to be final. Keep to any revision deadline you are given, or ask for an extension.

For the cover letter, keep it to three paragraphs: (1) what you found, in one sentence with the specific advance; (2) why it matters beyond your subfield and to ChemComm's wide general readership; (3) a one-line note that your 5 suitable referees are entered in the submission system. RSC asks for the referee details in the submission system, not in the letter, and sends the cover letter to reviewers. Don't summarize your entire paper. State what's new and why it's interesting.

Before you format your manuscript, answer these questions honestly:

1. Can you state your new finding in a single sentence that would surprise a chemist in an adjacent subfield?

1. Does your paper keep to a small number of figures and tables, as RSC asks?

1. Is your ESI thorough enough to stand up to detailed scrutiny?

1. Have you checked the last 12 months of ChemComm and Angewandte Chemie for competing results?

1. Does your introduction get to the point within the first paragraph?

1. Can you explain why this result couldn't wait for a full article, and why the preliminary report matters now?

If you answered no to more than two, your paper probably isn't ready for ChemComm in its current form. That doesn't mean the science is bad. It might mean the format is wrong, or you need another month of data before the story holds together.

A Chemical Communications submission readiness check can help you test whether your paper's framing, figure load, and novelty argument match what ChemComm editors expect, before you spend time on the formal submission process.

If your result is genuinely field-changing, try Angewandte or JACS first.

If your work is computational without experimental validation, check whether comparable computational Communications appear in recent ChemComm issues, since computational chemistry and machine learning are among ChemComm's listed topic areas. PCCP or J. Chem. Theory Comput. may be better fits.

If your paper needs more than 3.5 pages of main text, consider Chemical Science or an RSC specialty journal (Dalton Transactions, Organic & Biomolecular Chemistry) depending on your subfield.

RSC publishes neither an acceptance rate nor a desk-rejection rate. The most common desk-rejection reasons are insufficient novelty and incomplete characterization.

A Chemical Communications scope and readiness check identifies the specific issues that trigger desk rejection before you submit.

For manuscripts targeting Chemical Communications, five patterns generate the most consistent desk rejections worth knowing before submission.

The compressed article disguised as a Communication. According to ChemComm's author guidelines, Communications are limited to 5 total pages with 3.5 pages for main text, requiring that the scientific story be self-contained within that constraint rather than reduced from a longer paper. We see this pattern in manuscripts we review more frequently than any other ChemComm-specific failure.

Papers with five or more main-text figures, multi-column introductions, or conclusions that depend on ESI results face desk rejection when editors identify that the manuscript reads as a truncated article. In our experience, a meaningful share of manuscripts we review targeting ChemComm exceed the practical figure limit or have an introduction structure inappropriate for the 3.5-page main text constraint.

The optimization study without a new finding. Per ChemComm's editorial standard, Communications must report genuinely new chemistry, a new reaction, new material property, or unexpected selectivity, not a parameter survey demonstrating that a known transformation performs better under optimized conditions. We see this in a meaningful share of manuscripts we review for ChemComm, where authors report solvent screening, catalyst loading optimization, or substrate scope extension for reactions already established in the literature without identifying a new mechanistic insight.

Editors consistently reject papers where the conclusion is that optimized conditions were found rather than that something new was discovered. In practice desk rejection tends to occur when an editor identifies that the advance is incremental optimization rather than a new finding.

The paper with subdisciplinary appeal only. According to ChemComm's editorial scope, the journal publishes chemistry across organic, inorganic, physical, analytical, biological, and materials subfields but requires that submissions be of interest to chemists outside the specific subspecialty.

In our experience, a meaningful share of manuscripts we review for ChemComm target such a narrow ligand system, reaction type, or material class that the finding would only be interesting to the small number of specialists who work in exactly that area. Editors consistently screen for papers where the novelty is legible to a working chemist outside the subfield.

In practice desk rejection tends to occur when an editor identifies that the chemistry advance requires deep specialist knowledge to appreciate.

The ESI-dependent story.

Per ChemComm's format requirements, the main text must stand as a coherent scientific story without requiring the reader to consult ESI for essential results. We see this in a meaningful share of manuscripts we review for ChemComm, where key experimental results, mechanism-supporting data, or control experiments central to the paper's claims appear only in supplementary material. Editors consistently flag papers where the logical flow of the main text breaks because essential data is not in the main text.

The purely computational Communication.

ChemComm lists computational chemistry and machine learning among its major topic areas, but a computational Communication still has to show significance to a broad chemistry readership. We see this in a meaningful share of manuscripts we review for ChemComm, where DFT calculations or molecular dynamics simulations predict novel chemistry without experimental corroboration. Purely computational papers may fit better in PCCP or Journal of Chemical Theory and Computation.

Before submitting to Chemical Communications, a ChemComm manuscript fit check identifies whether the Communication format, novelty threshold, and breadth of chemistry interest meet the journal's editorial bar before you commit to the submission.

Ready to submit if:

• You can pass every item on this checklist without qualifying language

• An experienced colleague in your field has read the manuscript and agrees it's competitive

• The data package is complete, no pending experiments or analyses

• You have identified why ChemComm specifically (not just prestige) is the right venue

Not ready yet if:

• You skipped items on this checklist because you "plan to add them later"

• The ESI still has draft or incomplete characterization text

• Key figures are drafts rather than publication-quality

• You cannot articulate what distinguishes this paper from recent ChemComm publications
