Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
CP 1 and CP 2 are proposed as red luminescence materials, with room-temperature emission maxima at 600 and 595 nm.
Caveat: No quantum yield or long-term photostability data are reported in the main text.
main p.7 · 4. Conclusion · Figures 5 and 6 · Linked to 2 structured results
The authors suggest the two coordination polymers can be used as solid-phase semiconducting materials because their conductivities are in the 10^-6 S/cm range.
Caveat: Only room-temperature pressed-pellet four-point-probe conductivity is reported; no carrier type, activation energy, mobility, or temperature-dependent transport data are given.
main p.7 · 3.7. Electrical conductivity · Linked to 2 structured results
Both products are 1D Cu(II) coordination polymers: CP 1 is linked by picolinate ligands along [100], and CP 2 is linked by sulfate ligands along [001].
Caveat: Full crystallographic coordinates/geometric parameters are available in the SI text Tables S1-S6; CIF files were not required for this extraction.
main p.3 · 3.2. Crystal structure of CPs · Figures 2 and 4 · Linked to 6 structured results
The 2-Hpyc ligand in CP 1 is generated in situ by hydrothermal semi-decarboxylation of 2,6-pydc, supported by GC-MS analysis of the solution phase.
Caveat: GC-MS evidence identifies solution-phase methyl ester species after esterification; the rendered SI supplies retention-time labels, but no raw chromatogram data file is available.
main p.4 · 3.3. In situ hydrothermal decarboxylation and formation · Scheme 4 and Figure S1 · Linked to 6 structured results
Zn(II) sulfate is proposed to have a catalytic role in decarboxylation and new ligand formation under high-temperature subcritical water conditions.
Caveat: Mechanistic support is based on comparative reactions described in text; detailed data are not shown in the main article.
main p.5 · 3.3. In situ hydrothermal decarboxylation and formation
The paper attributes semiconductor-level charge transport to strong covalent bonding and regular infinite polymeric-chain structures that delocalise electronic states.
Caveat: This is a qualitative interpretation; no band-structure or temperature-dependent conductivity data are provided.
