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

Oriented MOF-74(Mg) films on gold are highly porous and are attractive candidates for on-chip host-guest experiments.

Caveat: BET value is normalised to geometric surface area and is partly attributed to the roughly 3 um film thickness.

Application RelevanceSupport assessment: High

MOF-74(Zn) and MOF-74(Mg) films show blue emission with similar PL lifetimes and homogeneous confocal PL maps.

Caveat: Detailed lifetime analysis focused on Zn and Mg because Ni and Co emission intensities were low.

5902 · Conclusions · Figure 6 · Linked to 6 structured results

CaveatSupport assessment: High

This paper does not provide first-hand electrical-transport, thermoelectric or electrochemical performance measurements for the MOF-74 films.

Caveat: The paper discusses potential optical or electrical properties and cites earlier conductive MOF-74 work, but no transport data are measured here.

Structure Property LinkSupport assessment: High

MOF-74 films based on different metal ions grow with substantially different modes and orientations on the same surfaces.

Caveat: Mechanistic interpretation is based on observed morphologies and time-dependent growth experiments, not direct in situ spectroscopy.

Synthesis MechanismSupport assessment: High

Vapor-assisted conversion enables on-surface growth of crystalline MOF-74(M = Zn, Mg, Ni, Co) thin films on multiple substrates with tunable crystallite orientation.

Caveat: Orientation control was strongest for Zn and Mg; Ni and Co remained nonoriented after screening.
