Electroactive Azo Polyamide Based Oligoaniline: Synthesis and Characterization

Abstract

ABSTRACT:An alternating copolymer, electroactive azo polyamide was prepared by oxidative coupling polymerization of oligoaniline macromonomer and p-phenylenediamine. The molecular structure of the polyamide was characterized by Fourier-transform infrared (FT/IR) spectra, 1 H NMR spectroscopy, elemental analysis (EA) and gel permeation chromatography (GPC). UV-vis spectrum was used to monitor the chemical oxidation process and the photoisomerization of the polymer. The electrochemical activity of the polyamide was checked by cyclic voltammetry (CV) and the mechanism of electrochemical oxidation process was well studied. Moreover, the thermal characteristics of the polyamide were evaluated by thermogravimetric analysis (TGA).

Electroactive polymer with oligoanilines in the main chain and azo chromophores in the side chain: synthesis, characterization and dielectric properties

“…The as-synthesized polymer exhibited very good solubility in comparison to the similar polymer with azo chromophores in main chain in our previous work. 32 Its electroactive properties were similar to oligoaniline, as characterized by electrochemical method. Besides, UV-vis spectra have showed that the intrinsic photoisomerization of the azo chromophores was maintained in the polymer.…”
