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 materials decomposed upon 80 C thermal activation and showed only a small BET surface area, so permanent porosity was not established.
Caveat: BET value is reported generally for the materials, not separately for 4 and 5.

As-synthesised networks 4 and 5 contain neutral EDT-TTF cores and do not show the organic radical EPR signature.
Caveat: Neutral assignment is inferred by authors from bond distances and EPR absence of radical signal.

Interdigitation/stacking of 1D coordination networks organises sulfur-rich EDT-TTF cores into stacks that can support transport after post-synthetic oxidation.
Caveat: The study demonstrates enhanced conductivity after oxidation, but does not provide microscopic transport modelling.
p003 / journal p2409 · Conclusion · Linked to 5 structured results
Iodine solution treatment surface-oxidises networks 4 and 5, generates EDT-TTF radical cations, and increases conductivity from insulating controls to about 10^-6-10^-7 S cm^-1 in single crystals.
Caveat: Iodine-containing anions were not clearly resolved crystallographically; authors argue doping is surface-limited.

No clear orientation effect was observed in single-crystal conductivity; values along the TTF stacking direction and perpendicular direction were similar.
Caveat: Device-to-device spread is large and all values are rounded figure-read values.
