Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Compound 1 is regenerable by dissolution and room-temperature recrystallisation because the nanotube array is constructed by non-covalent interactions.
Caveat: Recovery is described qualitatively; no regenerated-sample conductivity or quantitative recovery yield is reported.

Desolvated 1 has very low N2 and CO2 uptake despite crystallographic voids, which the authors attribute to a lack of effective adsorption sites in the nanotube.
Caveat: Endpoint uptake values are approximate readings from rendered Fig. S6; the main text provides only a qualitative gas-rejection conclusion.
4 · 3.4. Guest adsorption · Fig. S6 · Linked to 3 structured results
Iodine uptake enhances the pellet electrical conductivity of compound 1 by approximately two orders of magnitude.
Caveat: Conductivities are very low absolute values and were measured by two-probe pellet geometry; contact effects are possible.
5 · 3.5. Guest tunable electric conductivities · Fig. 5 · Linked to 4 structured results
The nanotube array contains hexagonally aligned pi-stacked columns intended to provide through-space conductive pathways while retaining interior channels.
Caveat: The structural pathway is well supported crystallographically, but anisotropic or single-crystal directional conductivity was not reported.
2 · Introduction and Fig. 1 caption · Fig. 1 · Linked to 6 structured results
Captured iodine interacts with nitro groups on dnbn, as inferred from enhanced IR nitro absorption and XPS I 3d, N 1s, and O 1s changes.
Caveat: The charge-transfer assignment is mechanistic interpretation from spectroscopy rather than a directly measured transport pathway.
5 · 3.4. Guest adsorption · Fig. 4 · Linked to 8 structured results
Under electric field, iodine in the pore is proposed to transform into solvent-I+I-, increasing ionic strength and conductivity.
Caveat: The ionisation mechanism is proposed by the authors; the paper reports conductivity and spectroscopy but not direct in situ speciation under bias.
