Özet

Synthesis of comonomer, possessing 4,4'-dinonyl-2,2'-bithiazole and 3,5-diphenyldithieno[3,2-b;2′,3′-d]thiophene (T-NBT-Ph₂DTT-NBT-T) units, was achieved using Stille cross coupling reaction. Its electropolymerization was conducted in acetonitrile, containing 0.1 M NaClO₄ + 0.1 M LiCIO₄ (MCIO₄). Properties of the polymer film, obtained P[T-NBT-Ph₂DTT-NBT-T], were characterized by electrochemical techniques. Effect of the polymerization charge on the redox behavior of the polymer film was investigated, and the film was further characterized by UV-visible spectrophotometric measurements. Corresponding electrical equivalent circuit was applied to the experimental electrochemical impedance spectroscopy (EIS) data to explain the parameters of each element and the interface of the Pt/P[T-NBT-Ph₂DTT-NBT-T]/MCIO₄ system. The band gap of the polymer was obtained as 1.86 eV by in situ spectroelectrochemical measurements. Good stability in the oxidized state was verified experimentally. Molecular orbitals and electropolymerization of the comonomer were investigated at DFT level.
