Advanced Materials Supporting Information (advmat-supplementary)

When to trigger

• The manuscript is over the Communication/Article format and detail must move out of the body
• A reader cannot judge the material without opening the SI
• You have extended datasets, full recipes, or control experiments with no home
• You are unsure what belongs in the SI versus what must stay in the main text
• Reviewers of a prior version asked for data that would bloat the body

The stand-alone rule (non-negotiable)

The main text must be fully understandable and convincing on its own. The Supporting Information supports the paper; it must never be load-bearing for the central advance. A reader who never opens the SI should still grasp the material, the decisive evidence that it is what you claim, the property, and the benchmarked function.

• The central advance, the decisive characterization, and the headline benchmarked metric live in the main text.
• The SI holds the exhaustive backup a skeptical referee or a group trying to reproduce the work will want.
• Every SI item is cited from the main text at the point it becomes relevant.

If removing the SI collapses the argument, the partition is wrong — pull the essential piece back into the main text (and trim elsewhere via advmat-length-management).

SI organization

• Mirror the main text's logic: order SI sections to match the order they are cited.
• Give SI sections clear headings and self-contained captions; label SI figures/tables distinctly (Figure S1, Table S1).
• Include an SI Experimental Section detailed enough to reproduce the material if the main-text version is condensed.
• Keep the SI honest: it is peer-reviewed alongside the paper — not a place to bury weak or contradictory data.
• Provide computational and raw-data availability per current Wiley policy (repository + DOI where required).

Checklist

• The main text is convincing without ever opening the SI
• No decisive evidence for the advance lives only in the SI
• Every SI item is cited from the main text at the relevant point
• SI sections ordered to match their citation order
• SI figures/tables labeled S1, S2, ... distinctly from main-text items
• The full reproducible recipe/protocol is in the SI if condensed in the body
• Nomenclature and units are consistent between main text and SI
• Data/computational availability handled per current Wiley policy

Anti-patterns

• A paper that silently depends on the SI to be believed
• Burying the decisive characterization or the benchmarking in the SI
• An SI that is a disorganized data dump rather than a structured appendix
• SI figures referenced out of order or never cited from the body
• Nomenclature/unit drift between main text and SI
• Using the SI to smuggle in claims the referees did not scrutinize

Output format

【Main text stands alone】yes / fix (pull back: ...)
【SI sections】S1: ... / S2: ... (cited from body?)
【Decisive evidence only in SI?】none / move back: ...
【SI figure/table labels】S-prefixed?  yes / fix
【Reproducible recipe present】yes / fix
【Nomenclature consistent body↔SI】yes / fix
【Next】advmat-writing-style or advmat-length-management
