Since the discovery of conductive polymers, one of the most promising innovations in the field of polymer chemistry, these materials have been used in many practical applications. However, new monomers are being designed to overcome some of the disadvantages of conductive polymers, such as their inherent stability, low optical and electrical properties. It is known that minor arrangement on the monomer structure lead to very large changes in the polymer properties. In this study, a thienyl pyrrole monomer, one of the most studied monomers in the field of conductive polymers, has been produced using hydrazine derivatives instead of amines. For this purpose, the model monomer, N-phenyl-2,5-di(thiophen-2-yl)-1H-pyrrol-1-amine, was synthesized and the optical, electrochemical and electrochromic properties of its conductive polymer were investigated. Furthermore, copolymer studies with 3,4-ethylenedioxythiophene (EDOT) have been done to emphasize the importance of copolymerization on electrochromic properties of the conducting polymers. Effects of the feed ratio of the monomers and applied potential for copolymerization on optical and electrochemical properties of the electrochemically synthesized copolymers were investigated in detail.
