Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The article motivates conductance photoswitching in the introduction, but reports no first-hand electrical conductivity, charge mobility, thermoelectric or electrochemical device measurements for these frameworks.
Caveat: Extraction therefore contains no electrical_transport, thermoelectric or electrochemistry_application measurement rows.

CoDy, CoEu and FeDy are isostructural 3D cyanide-bridged 3d-4f heterobimetallic viologen frameworks in monoclinic C2/c.
Caveat: FeDy crystallographic summary is from the SI table because the supplied CIF text lacks an FeDy block.

After UV-vis irradiation, chiMT increases at room temperature because photogenerated radicals add magnetic response and couple ferromagnetically with lanthanide cations.
Caveat: FeDy percentage is taken from the Fig. 5c annotation; the main text does not report the numeric percentage.
4964 · Conclusions · Fig. 5 · Linked to 3 structured results
Short carboxylate-oxygen to pyridinium-nitrogen contacts and anion-pi/hydrogen-bonding interactions are proposed to favour photoinduced electron transfer.
Caveat: The authors state these distances alone do not explain all differences in photoresponsivity.

Photochromism is attributed to photoinduced electron transfer that generates viologen radicals; in FeDy, partial Fe(III) to Fe(II) reduction also contributes.
Caveat: This is a photochemical/electron-transfer mechanism claim, not a measured bulk electrical-conductivity result.
