Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: Medium

The authors claim high optical and electrical conductivity and propose mid-infrared biosensor relevance.

Caveat: Conductivity values are calculated from optical spectra; no direct electrical transport device measurement is reported.

9 · 4.5 Optical study · Figs. 13-14 · Linked to 3 structured results

Application RelevanceSupport assessment: High

DZTGD exhibits strong optical limiting behaviour with a 9.72 J cm-2 threshold.

Caveat: Application test is optical limiting, not charge transport.

Phase AssignmentSupport assessment: High

DZTGD single crystals belong to the triclinic crystal system with centrosymmetric P -1 space group.

Caveat: CIF was not provided for independent validation.

16 · 5 Conclusion · Linked to 3 structured results

Structure Property LinkSupport assessment: High

The material shows second- and third-order nonlinear responses, including SHG 1.61 times KDP and hyperpolarizability of 7.60 × 10^-36 esu.

Caveat: The title compound is centrosymmetric by SXRD, so the SHG interpretation may need expert review; extracted as reported.

Structure Property LinkSupport assessment: High

The dehydrated DZTGD crystal is thermally stable up to about 120 °C.

Caveat: Atmosphere and heating rate are not reported in the extracted main text.

Transport MechanismSupport assessment: Medium

Negative entropy and positive Gibbs free energy are interpreted as low thermal decomposition, ordered nature, and non-spontaneous dissociation.

Caveat: This is a thermal kinetic interpretation and not electronic transport.
