Abstract: This article presents the synthesis, characterization and electrochemical polymerization conditions of 4, 5-dithiophene imidazole (Th2-Im) co-monomer with donor-acceptor character carrying thiophene and imidazole monomer synthesized using Still Cross Coupling reaction. The obtained synthesis product (Th2-Im) was characterized by FT-IR, XPS and SEM images. In the synthesis structure, the presence of S atom belonging to the Th ring was observed in the 175 eV region, and the presence of N atom belonging to the Im ring was observed in the 411 eV region. In addition, B atom, which would indicate the presence of dopant anion, was observed in the 202 eV region. It was determined by SEM images that Poly (Th2-Im) had a more distinct and regular geometric texture than Poly (Th) morphologically. It was determined that Th2-Im was oxidized at 0.6 V from electrochemical polymerization. From monomer free CV, it was determined that Poly (Th2-Im) showed 3 oxidation peaks as 0.25V, 0.75V and 1.2V and 3 reduction peaks as 0.7V, 0.4V and 0.1 V. It was determined that the synthesis polymer obtained from these data could be polymerized more easily than Th and Im and the donor-acceptor character could be clearly observed in CV graphs.
