ABSTRACT
1-(3-Methylthiophen-2-yl)pyrene (MTP) monomer was successfully synthesized via coupling reaction. A novel conjugated copolymer based on 1-(3-methylthiophen-2-yl)pyrene (MTP) and 3,4-ethylenedioxythiophene (EDOT) was electrochemically synthesized and characterized. Characterizations of the resulting copolymer P(MTP-co-EDOT) were performed by cyclic voltammetry (CV), UV-vis spectroscopy and scanning electron microscopy (SEM). Compared with the MTP and the EDOT homopolymers, P(MTP-co-EDOT) film had distinct electrochromic properties via spectroelectrochemical analysis, and it exhibited four different colors (purple, brown, grass green and dusty blue) under various potentials. Moreover, the copolymer film showed high optical contrasts and satisfactory response times. An electrochromic device (ECD) based on P(MTP-co-EDOT) and poly(3,4-ethylenedioxythiophene) (PEDOT) was constructed and characterized. The ECD was found to have a high optical contrast, fast response time, satisfactory optical memories and good redox stability.
