Three soluble electrochromic copolymers based on 4,4-di-octyl- cyclopentadithiophene (DOCPDT): PDOCPDT-OT, PDOCPDT-PT, and PDOCPDT-Cz were synthesized and the electrochromic properties were investigated. Colorimetric analysis revealed that red-colored PDOCPDT-OT, green-colored PDOCPDT-PT and their blue mother polymer PDOCTDT are cathodic coloration polymers. PDOCPDT-Cz is yellow in its neutral state and shows an anodic electrochromism. The structural flexibility, color diversity, processibility and good electrochromic performance make octyl-cyclopentadithiophenecontaining polymers prominent candidates for electrochromic applications.
