Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu3(HHTATP)2 nanorod pellets reach the highest reported electrical conductivity among 2D MOFs featuring CuO4 metal nodes in the authors' comparison.
Caveat: The claim is relative to comparison tables in this work and the literature set cited there.

The measured accessible BET surface area is far below the theoretical surface area, likely because of stacking faults and pore occlusion.
Caveat: This is the authors' interpretation of lower experimental porosity relative to the DFT model.

Acid-mediated solvation/reprecipitation retains the principal Cu3(HHTATP)2 PXRD reflections, although with some amorphisation/stacking disorder.
Caveat: The profile includes a broad 15-25 deg hump attributed to rapid recrystallisation and disorder.

DFT predicts out-of-plane metallicity for the eclipsed bulk structure and a bulk in-plane gap matching the experimental optical gap.
Caveat: Electronic band structures are calculated models and density of states is shown at the gamma point only.

Pendant amines provide an acid-responsive chemical handle that enables Cu3(HHTATP)2 dispersion/dissolution in DMSO/TFA and subsequent spin-coated thin-film fabrication.
Caveat: The paper describes homogeneous dark-blue solution formation; detailed molecular solvation mechanism is inferred from XAS and reprecipitation data.
11495 · Results and Discussion · Figures S15-S17 · Linked to 3 structured results
Charge transport in Cu3(HHTATP)2 films is assigned mainly to hole conduction, and FET transfer curves suggest p-type behaviour.
Caveat: The FET response is described as slight; no mobility is reported.

Protonation of the amine-containing framework increases thin-film conductivity by about five-fold and lowers the activation energy for thermally activated charge transport.
Caveat: Conductivity comparison is between films processed with and without the basic Et3N/THF wash.
