The electrochemical polymerizations of thieno[3,2-b]thiophenes resulted in three polymers with different unit compositions, which exhibited varied electrochemical reversibility and charge storage capabilities due to the structural units present.
Electrochemical polymerizations of thieno[3,2-b]thiophenes (TT), named PhTTTPA, CH(3)OPhTTTPA and CNPhTTTPA, possessing pH, 4-CH3OPh, 4-CNPh and triphenylamine (TPA) units, were performed and their corresponding polymers P[PhTTTPA], P[CH(3)OPhTTTPA] and P[CNPhTTTPA] were obtained, respec-tively. The polymer films were characterized by cyclic voltammetry (CV), electrochemical impedance spec-troscopy (EIS) and spectroelectrochemical measurements, which suggested that while the presence of strong electron donating TPA unit provided them with better electrochemical reversibility, strong elec-tron withdrawing-CN group lowered the oxidation potential of P[CNPhTTTPA] along with enhancement of its charge storage character.
