Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
At 978 m2/g, Mn2(DSBDC) is claimed to have the highest surface area among MOFs demonstrating intrinsic charge delocalisation at the time of publication.
Caveat: Comparative statement depends on the literature available in 2013.

The authors explicitly state that an alternative charge-transport pathway may involve transfer through the benzene ring of the 1,4-benzenedithiol moiety.
Caveat: Experiments to test this possibility were stated as underway, not reported in this paper.

The FP-TRMC and TOF data are interpreted as revealing intrinsic charge mobility because the carrier displacement length is only 2-3 nm.
Caveat: Transport measurements were performed on MOF/PMMA composite films, not on neat monoliths or single crystals.

Replacing oxygen atoms with sulfur in metal-ligand chains is presented as a redox-matching strategy for porous crystalline materials with high charge mobility.
Caveat: Generality to other M2(DEBDC) materials is proposed, not demonstrated here.
main p.8188 · Summary · Linked to 4 structured results
The similar methanol-exchanged and activated mobilities suggest that the charge transport pathway is probably the Mn-S chain and is not strongly affected by solvent.
Caveat: Authors note an alternative pathway through the benzene ring may also be possible.
