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

Compound 1 also shows anticancer activity, with the strongest reported MTT response against MDA-MB-231 cells among the tested cancer cell lines.

Caveat: Biological assay protocols are in the SI and are outside the core conductive-MOF transport focus.

Phase AssignmentSupport assessment: High

Compound 1 is assigned as a crystalline Zn(II) coordination framework with tdc2- and pcih bridges; local 2D rectangular sheets are extended into a 3D architecture by pcih bridging and supramolecular interactions.

Caveat: SI crystallographic tables were supplied, but the CIF/CCDC data file itself was not local.

Structure Property LinkSupport assessment: Medium

SCLC analysis indicates higher effective mobility and diffusion length under illumination, supporting improved charge-transfer kinetics in the light phase.

Caveat: The SI supplies the capacitance-frequency plot and equations, but dielectric constant is inconsistent between main-text prose/SI prose and Table 2.

Transport MechanismSupport assessment: High

Compound 1 behaves as a semiconducting MS-junction material whose conductivity and Schottky parameters improve under illumination.

Caveat: SI provides device fabrication details and equations, but the metal top-electrode identity is inconsistent between Al/gold wording.
