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

PM1-based NeuVS devices support temporal light encoding, improved blue-colour extraction, trajectory display, and over-95% action recognition accuracy.

Caveat: Colour extraction and action recognition are simulations using measured device responses rather than standalone hardware classification experiments.

9-11 · 3.4-3.5 and Conclusion · Figures 4H and 5 · Linked to 5 structured results

CaveatSupport assessment: High

Although the paper uses MOFs in device dielectrics, it does not report electrical conductivity, thermoelectric properties, electrochemical transport, or porosity measurements of a conductive MOF framework.

Caveat: The assigned category is thin-film device/application; MOFs are dielectric/polymer-coordination components.

2-6 · Abstract; 3.2 · Figure 2; Table 1 · Linked to 2 structured results

CaveatSupport assessment: Medium

Adding Zr salts or Zr6 clusters alone decreases device performance, indicating that metal clusters in the MOF do not by themselves account for photoelectrical improvements.

Caveat: PZ1/PZ2 quantitative values are figure-only and are not exactly tabulated in text.

Composite RoleSupport assessment: High

Zr-BTB coordinates with PAA carboxyl groups to improve polymer ordering and crystallinity, evidenced by new diffraction features, higher coherence lengths, increased rDoC, MOF peaks in composites, and modelling of extended PAA chains.

Caveat: Zr-BTB synthesis recipe itself is cited to an external previous method and not reproduced in the supplied documents.

Structure Property LinkSupport assessment: High

Moderate Zr-BTB loading in PM1 improves C10-DNTT ordering on the dielectric and gives the best mobility, Ion/Ioff, photosensitivity, and dynamic response, whereas excessive MOF loading in PM2 lowers performance.

Caveat: Electrical transport is through C10-DNTT OFET channel; no intrinsic conductive-MOF transport is measured.

4-6 · 3.2 · Figure 2; Table 1; Table S3 · Linked to 7 structured results

Synthesis MechanismSupport assessment: Medium

The coordination between MOF nodes and polymer carboxyl groups is important, because Zr-BTB benefits carboxyl-containing polymers but harms PAN devices.

Caveat: Control data are mostly trend-level extractions from text/figures rather than exact tabulated values.

6-7 · 3.2 · Supporting Information Figures S19-S21 · Linked to 3 structured results

Transport MechanismSupport assessment: Medium

A moderate amount of MOF in PM1 reduces intermolecular hydrogen bonding, leaves freer hydroxyl groups, and enhances interfacial dipoles that generate more photocarriers.

Caveat: SFG evidence is author-interpreted; numerical peak intensities are not extracted.
