Abstract

Electrochemical copolymerizations of 2,3-di(2-thienyl)quinoxaline (M1), 6-methyl-2,3-di(2-thienyl)quinoxaline (M2), and 2,3-di(2-thienyl)quinoxaline-6-yl)(phenyl)methanone (M3) with 3,4-ethylenedioxy thiophene (EDOT) were carried out in CH3CN/TBABF(4) (0.1M) solvent-electrolyte couple via potentiodynamic electrolysis. The obtained copolymers were characterized by cyclic voltammetry (CV), Fourier transform-infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and thermogravimetry analyses (TGA). The conductivity measurements of copolymers and PEDOT were performed by the four-probe technique. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 120: 1713-1719, 2011
