Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The authors identify P-3,4-HBA-Cr as the most useful polymer because it combines solubility, high electrical conductivity and high thermal stability, with potential electronic, optoelectronic, electroactive and photovoltaic applications.
Caveat: Application relevance is proposed; no device demonstration is reported.
1,8 · Abstract; Conclusions · Linked to 4 structured results
SEC shows P-3,4-HBA-Cr is a soluble polymer/oligomer with a single fraction and approximately 21-22 repeat units.
Caveat: SEC was reported only for P-3,4-HBA-Cr.
4 · Section 3.2 · Linked to 4 structured results
The polymer spectra differ from the monomer and new 600-620 cm^-1 bands are assigned to metal-oxygen coordination, supporting formation of metal-chelate coordination polymers.
Caveat: Structural assignment is spectroscopic; no crystallographic structure is reported.
4 · Section 3.1 · Table 1; Fig. 1 · Linked to 4 structured results
P-3,4-HBA-Cr has a smaller optical band gap than 3,4-HBA, which the authors link to higher electrical conductivity.
Caveat: Only 3,4-HBA and P-3,4-HBA-Cr could be measured by UV-vis because the other polymers were insoluble.
6 · Section 3.3 · Fig. 4 · Linked to 4 structured results
The coordination polymers are thermally stable; P-3,4-HBA-Zn has the largest onset temperature while P-3,4-HBA-Zr has the highest carbon residue at 1000 °C.
Caveat: Thermal stability ranking depends on chosen metric (onset temperature versus carbon residue).
7-8 · Section 3.5; Conclusions · Table 3 · Linked to 2 structured results
The monomer and metal coordination polymers are semiconducting, and iodine vapour doping increases conductivity for several samples, especially 3,4-HBA, P-3,4-HBA-Cu and P-3,4-HBA-Mn.
Caveat: Conductivity values are reported for pressed pellets; no uncertainty or sample dimensions are provided.
