Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

SJTU-201 shows the best reported ENRR performance in this paper, with 87.1 +/- 1.8% NH3 FE and 56.0 +/- 1.5 ug h-1 mgcat-1 yield at -0.30 V vs RHE.

Caveat: Electrode is a MOF/carbon/Nafion composite ink; pristine powder properties are separately extracted.

10 · Electrocatalytic Activity · Figure 6; Table S6 · Linked to 2 structured results

Structure Property LinkSupport assessment: High

Strong interlayer interactions in multilayer-stacked SJTUs shrink the bandgaps relative to monolayers, yielding ultra-narrow direct gaps of 0.10-0.28 eV.

Caveat: Bandgap mechanism is based on DFT calculations and local DOS rather than direct transport activation measurements.

6 · Photoconductivity · Figure 5; Figure S51 · Linked to 6 structured results

Synthesis MechanismSupport assessment: High

Direct coordination of aryldiisocyanide ligands with low-valent Rh(I) produces air-stable, metal-carbon coordinated 2D MOFs with Rh-C4 sites.

Caveat: Coordination assignment combines spectroscopy, XPS/EXAFS, and model compounds; no single-crystal structure of SJTUs is reported.

2 · Design and Synthesis · Figures S20-S33 · Linked to 5 structured results

Transport MechanismSupport assessment: Medium

In situ ATR-SEIRAS, DEMS, and DFT support dual ENRR pathways on Rh(I)-C4 sites: associative distal and two-electron transfer via N2Hx species.

Caveat: DEMS m/z assignments include possible overlaps; pathway conclusion combines experimental signatures and DFT.

Transport MechanismSupport assessment: High

TRTS/Drude-Smith fitting indicates high short-range photocarrier mobilities, with SJTU-201 reaching 560 +/- 46 cm2 V-1 s-1 intrinsic mobility.

Caveat: These are photogenerated short-range TRTS mobilities; dc-limit values are much lower (9-17 cm2 V-1 s-1).
