Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Guest-induced conductivity enhancement is reversible because prolonged washing removes dopants and conductivity drops near the undoped value.
Caveat: Exact post-wash conductivities by guest are not in the main text.
897 · Results and discussion · Linked to 2 structured results
Two-probe pellet measurements are unsuitable for comparing undoped and doped BMOF because pellets disintegrate in guest solutions and contact/packing differences cannot be nulled; four-probe films avoid these issues.

Large C60 molecules do not noticeably change conductivity because they are size-excluded from BMOF pores.
Caveat: Main text reports unchanged conductivity and C60 diameter; direct uptake data are not present.
897 · Results and discussion · Linked to 2 structured results
The stronger pi-acidic and cationic MV2+ guest enhances BMOF conductivity more effectively than DFDNB or DNT, likely due to stronger donor-acceptor interactions and possible ionic contribution to charge mobility.
Caveat: Mechanistic interpretation is inferred by the authors rather than directly separating electronic and ionic contributions.

Annealed ZnO-coated substrates enable selective BMOF film growth and provide sufficient electrical contact to the underlying electrode.
Caveat: Selective-growth mechanism is proposed by the authors; electrochemical contact evidence is described in the SI/main text.

BMOF film conductivity can be fine-tuned by intercalating complementary pi-acidic guests that promote long-range electron delocalisation through guest-host pi-stacks.
Caveat: SI Tables S1-S2 provide raw/corrected resistance and individual-device conductivity values; main text reports headline conductivities.
