Synthesis and characterization of redox-active group containing conducting polymers and investigation their of electrochromic properties

In this study, three novel, redox-active group containg monomers namely, 4-ferrocenyl-1[2-(2,5-di-thiophene-2-yl-pyrrole-1-yl)-ethyl]-1H-[1,2,3]triazole (SNS-Fc), 4-ferrocenyl-1-(4-pyrrole-1-yl-butyl)-1H-[1,2,3]triazole (Py4Fc), and 4-ferrocenyl-1-(6-pyrrole-1-yl-hexyl)-1H-[1,2,3]triazole (Py6Fc), were synthesized. Syntheses of the monomers and post polymerization functionalization were both achived via ?Click Chemistry?. Characterization of the monomers were performed via 1H-NMR, 13C-NMR, FTIR, UV-Vis, Fluorescence and High Resolution Mass Spectroscopy techniques.Electrochemical behavior of monomers were investigated by cyclic voltammetry and the corresponding homopolymers were obtained under appropriate conditions. In addition, electrochemical copolymerization of SNS-Fc in the presence of EDOT was achived and the resultant polymer was characterizated. Moreover, electrochromic properties of all the polymers were investigated through spectroelectrochemistry, kinetic studies and color measurements. With this study, affect of ferrocene group and copolymerization on the properties of SNS and pyrrole based conducting polymers were evaluated.
