Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Pressure treatments can alter Zn2TTFTB THz resonances and slightly increase photoconductivity magnitude, so caution is warranted when preparing pressed MOF samples.
Caveat: The increase in photoconductivity magnitude is qualitative; no numeric increase was reported.

The Drude-Smith backscattering parameter close to -1 indicates dominant backscattering at interfaces, giving insight into grain-boundary effects in micrometre-sized Zn2TTFTB crystallites.
Caveat: Interpretation is model-based and inferred from Drude-Smith fit parameters.

Zn2TTFTB charge transport is assigned to a through-space mechanism in which the framework arranges TTFTB linkers so that sulfur moieties overlap and form conductive channels.
Caveat: The structural mechanism is cited to the prior Zn2TTFTB literature and supported here by structural assignment rather than directly measured electronic coupling.

The frequency-dependent conductivity is well described by the Drude-Smith model, validating that Zn2TTFTB exhibits photoconductivity.
Caveat: Fit excludes resonance regions from 0.25-0.75 THz and above 2 THz.
