Synthesis and characterization of the polyaminophenol derivatives containing thiophene in side chain: Thermal degradation, electrical conductivity, optical-electrochemical, and fluorescent properties

摘要

Novel polyaminophenols, poly-2-3-thienylmethyleneaminophenol (P-2,3-TP), poly-3-3-thienylmethyleneaminophenol (P-3,3-TP) and poly-4-3- thienylmethyleneamino phenol (P-4,3-TP), were synthesized by oxidative polycondensation reaction. Metal complexes of P-2,3-TP were also obtained. The structures of synthesized compounds were confirmed by FT-IR, UV-vis, ~1H NMR, and ~(13)C NMR techniques. The characterization was made by TG-DTA, DSC, and gel permeation chromatography (GPC) analyses in addition to solubility tests. Electrical conductivities of polymers were measured by four-point probe technique. Fluorescence measurements were carried out in various solutions and optimum concentrations and maximal intensities were determined. The new synthesized polyaminophenols are good candidates for electronic, opto-electronic, and photovoltaic applications due to polyconjugated structures.
