The effect of the monomer feed ratio and applied potential on copolymerization: investigation of the copolymer formation of ferrocene-functionalized metallopolymer and EDOT

Abstract

In this study, we reported synthesis of ferrocene functioned conducting metallopolymer to enhance the understanding of properties of polymers. One of the crucial ways in the electrochromic polymer materials research was tuning color by means of copolymerization and change of polymer backbones and side groups. For this purpose, we synthesized copolymer of 4-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)amido ferrocenyl dithiophosphonate with EDOT via potentiodynamic electrolysis. Spectral and electrochemical characterizations of the copolymer were investigated. In addition, the spectral properties of the copolymers prepared by different applied potentials and different monomer feed ratio were studied. For the first time, copolymer composition and the monomer reactivity ratios were approximately calculated by using the spectral data.
