Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Post-synthetic exchange of Me2NH2+ by TTF*+ or MV2+ retains the crystalline framework and enables single-crystal-to-single-crystal transformation.
Caveat: Cation positions/valence allocation are difficult because of disorder.
18763-18764 · Abstract and Results and Discussion · Linked to 3 structured results
Solvent-accessible volume decreases from Me2NH2@1 to TTF@1 to MV@1, consistent with replacement by larger guests.
Caveat: Calculated by PLATON SQUEEZE excluding disordered solvent; not a gas adsorption measurement.
18764 · Results and Discussion · Linked to 3 structured results
Introducing redox-active TTF*+ or MV2+ cations increases pressed-pellet electrical conductivity by about two orders of magnitude relative to Me2NH2@1.
Caveat: Absolute conductivities remain low and the authors state this precludes a full temperature-dependence study.

The MV@1 EPR intensity decreases on cooling, interpreted as reduced carrier density in a semiconductor-like system.
Caveat: The conclusion is based on EPR intensity trends rather than direct variable-temperature conductivity.
18765-18766 · Results and Discussion · Figure 3b · Linked to 1 structured result
MV@1 shows the largest photocurrent because light-responsive MV2+ participates in charge transfer between TTFTB/MV2+ and TTFTB*+/MV*+ states.
Caveat: Mechanistic assignment is inferred from EPR, UV/Vis-NIR and photocurrent correlations; no direct time-resolved charge-transfer measurement is reported.
