Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Compound 1 selectively detects TNP with strong fluorescence quenching, low detection limit, and a large Stern-Volmer quenching constant.
Caveat: Sensing measured in ACN dispersion; real-world aqueous/solid-device sensing is not established here.
771 · Sensing of epNACs · Figures 10-12 · Linked to 4 structured results
Bulk compound 1 is phase-pure by PXRD and thermally stable to about 250 deg C after initial lattice-water loss.
Caveat: PXRD claim is qualitative; no refined PXRD residuals reported.
767 · Thermal Stability and Purity · Figures S4-S5 · Linked to 3 structured results
TNP quenching is attributed to a combined ICT-RET pathway, supported by DFT orbital energies, pi-pi interaction feasibility, spectral overlap, and nonlinear Stern-Volmer behaviour.
Caveat: Mechanism is inferred from spectroscopy and DFT rather than directly observing charge/energy transfer intermediates.
773 · Sensing of epNACs · Figures 12-15 · Linked to 4 structured results
The 2D rectangular-grid coordination sheet is assembled into a 3D supramolecular architecture through C-H...pi and pi...pi interactions among dangling 4-nvp ligands.
Caveat: Property linkage to transport is proposed qualitatively by the authors.

At low bias the device is ohmic, while high-bias transport is assigned to SCLC dominated by discrete trapping levels.
Caveat: Assignment is based on power-law analysis of device I-V curves rather than direct trap spectroscopy.
769 · Electrical Characterization · Figure 6 · Linked to 4 structured results
Compound 1 behaves as a semiconductor-like Schottky device material with conductivity enhanced by light soaking.
Caveat: Electrical data are thin-film device values, not intrinsic single-crystal conductivity; light-row charge-conducting parameters in Table 2 were partly unavailable in the supplied text/render.
