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.
Compound 1 is claimed to be readily regenerable and solution-processable, including recovery from MeOH/acetone and thin-film fabrication by cast coating/drop casting.
Caveat: Regeneration and thin-film protocols are only partly specified; no thin-film conductivity is reported.

The framework collapses upon solvent removal, so activated dry porosity or activated-framework transport interpretation should be treated cautiously.
Caveat: No gas-sorption measurement is reported in the available text.

The studied conductive framework is a supramolecular coordination framework alternative to conductive MOFs, not a conventional coordination-bonded conductive MOF.
Caveat: Included in the conductive-MOF evidence database because the paper frames the material as an isotropic conductive framework alternative to MOFs.
main p.1 · Abstract · Linked to 2 structured results
Compound 1 is assigned as a chiral, porous, cubic srs supramolecular framework constructed through both hydrogen bonding and intermolecular pi-pi interactions.
Caveat: checkCIF reports one level A solvent-accessible-void alert and the SI states SQUEEZE was used for highly disordered solvent.
main p.1 · Abstract · Linked to 4 structured results
The authors claim isotropic charge transport arises because the cubic structure contains pi-stacked helical columns along all three Cartesian coordinates.
Caveat: The paper reports pellet conductivity and cubic/three-directional column structure; the available text does not report separate directional single-crystal conductivity measurements.
main p.2 · Main text · Linked to 3 structured results
DFT HOMO/LUMO analysis supports a through-space pi-pi transport pathway along the stacked columns.
Caveat: The DFT calculation was performed on a finite helical-pitch column model rather than the infinite crystal.
main p.3 · Main text · Fig. 4 · Linked to 3 structured results
Compound 1 is described as semiconducting based on its 300 K pellet conductivity and optical band gap.
Caveat: Conductivity was measured by a two-probe pellet method; contact resistance and pellet dimensions are not fully reported in the available text.
