Abstract
An ionic conjugated polymer, poly(2-ethynylpyridinium bromide)having propargyl side chain(PEPB-P), was prepared by the activated polymerization of 2-ethynylpyridine with propargyl bromide in high yield. The electrochemical properties of PEPB-P were studied by using cyclic voltammograms. PEPB-P showed the well-defined and stable redox process at − 0.1 to + 1.6 V. The oxidation and reduction occurred at 0.84 and 0.69 V, respectively. The redox current value increased as the increased scan rate and the exponent of scan rate, x value was found to be 0.75, which means that the redox kinetics is mainly controlled by both electron transfer and diffusion process.
