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: Medium

The mild in situ route can directly synthesise TOM-Cu3(HITP)2 on desired substrates without a transfer process.

Caveat: Demonstrated on commercial ceramic-based gold IDE and adapted to quartz/glass for characterisation; broader substrate universality is asserted rather than systematically screened.

p004 · 2.2 Morphology · Figure S1 · Linked to 2 structured results

CaveatSupport assessment: High

The paper identifies Cu3(HITP)2 as an electrically conductive MOF but does not report a standalone film conductivity, mobility, Seebeck coefficient, or electrochemical conductivity value in the assigned documents.

Caveat: Electrical evidence in this paper is chemiresistive H2S sensor resistance/response rather than intrinsic transport metrology.

p002-p006 · Introduction / 2.5 H2S gas sensor · Figure 3h

Phase AssignmentSupport assessment: High

TOM-Cu3(HITP)2 film and ordinary Cu3(HITP)2 MOF are assigned as the same Cu3(HITP)2 substance, with slight differences in superficial Cu(I) contents and crystallinity.

Caveat: No CIF or Rietveld refinement is provided; TOM film peaks are broader and weaker.

Structure Property LinkSupport assessment: High

The TOM-micropore hierarchical structure dramatically improves room-temperature H2S sensitivity by facilitating gas mass transfer and exposure of active sites.

Caveat: Application comparison is made against a no-template Raw-Cu3(HITP)2 film; standalone conductivity and selectivity data are not reported in the assigned documents.

Synthesis MechanismSupport assessment: High

The quasi solid-liquid strategy transforms solid HATP aggregation within the PS template into water-insoluble Cu3(HITP)2 aggregation rapidly enough to retain the original TOM morphology.

Caveat: Mechanism is inferred from morphology retention and chemical reaction scheme, not time-resolved spectroscopy.
