Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Zn-m-TTFTB and Cd-m-TTFTB show two quasi-reversible one-electron redox processes assigned to TTF/TTF radical cation and TTF radical cation/TTF2+ couples.
Caveat: Solid-state CV peaks broaden with faster scan rates, indicating slow diffusion through the framework.

Different carboxylate coordination modes of the truncated m-TTFTB ligand give Zn-m-TTFTB a 2D framework and Cd-m-TTFTB a 1D chain-like structure.
Caveat: This is a structural interpretation from crystallography rather than a measured transport mechanism.

O-H...O hydrogen bonds play a vital role in assembling higher-dimensional structures in m-TTFTB and Zn/Cd-m-TTFTB.
Caveat: The claim is based on crystallographic packing analysis and hydrogen-bond tables; no perturbation experiment was performed.

Solid-state UV-vis-NIR absorption and EPR data support intramolecular charge transfer within the m-TTFTB ligand in the CPs.
Caveat: Charge-transfer assignment is spectroscopic; no direct carrier mobility or band-structure measurement is reported.
p005 / journal page 4945 · Conclusions · Figures 5-6 · Linked to 4 structured results
Electrical conductivity of Zn/Cd-m-TTFTB is closely related to S...S interactions in the single-crystal structure, with shorter S...S distances associated with higher conductivity.
Caveat: Only two new CPs are directly compared here; conductivity was measured on pressed pellets and remains low, so morphology/contact effects may contribute.
