Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
All four CPs are fluorescence turn-off sensors for TNP and DNP in aqueous dispersion, with CP2 most selective for TNP by quenching efficiency and Ksv.
Caveat: Sensing is based on laboratory fluorescence titrations; limits of detection are in micromolar range.
4537-4539 · Plausible Mechanism; Conclusions · Figure 13; Table S6 · Linked to 4 structured results
The authors describe the CPs as nonporous and hydrolytically stable due to tight coordination and weak interlayer interactions; no gas-sorption porosity measurement is reported.
Caveat: Nonporosity is stated in the discussion rather than supported by BET or gas sorption data in the extracted documents.

CSD4 is the best optoelectronic device among the four according to diode and charge-transport parameters.
Caveat: Best device claim is based on the reported parameter set, not independent replication.
4534 · Electrical Characterization · Tables S4-S5 · Linked to 8 structured results
The conductance trend 4 > 2 > 3 > 1 is attributed to differences between 3D dicyanamide frameworks and 1D thiocyanate chains, with more inorganic Cd/pseudohalide acceptor parts aiding charge transport.
Caveat: This is the authors' mechanistic interpretation; direct carrier-path mapping was not reported.

Fluorescence quenching is attributed to static quenching at lower analyte concentration, dynamic quenching at higher concentration, inner filter effects, PET and resonance-energy-transfer contributions.
Caveat: Multiple mechanisms are inferred from spectral overlap, DFT levels and lifetime decreases; mechanistic deconvolution is qualitative.
4537-4538 · Plausible Mechanism of Fluorescence Sensing · Figure 14; Table S8 · Linked to 3 structured results
Thin-film ITO/CP/Al devices based on CP1-CP4 show semiconductor behaviour and nonlinear rectifying Schottky-barrier-diode characteristics; conductivity increases under illumination.
Caveat: Conductivity values are reported for spin-coated thin films; film thickness is approximate for dielectric calculations.
