Abstract

Novel polyaminophenols, poly-2-[3-thienylmethylene] aminophenol (P-2,3-TP), poly-3-[3-thienylmethylene] aminophenol (P-3,3-TP) and poly-4-[3-thienylmethylene] amino 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, (1)H 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. (C) 2011 Wiley Periodicals, Inc.
