Novel Cross-Linked Conducting Polythiophene with Yellow-Green-Light-Emitting Properties and Good Thermal Stability

A novel conjugated polythiophene derivative with polymethacrylate attaching to the polymer backbone via an alkyl spacer was successfully synthesized. A methacrylate-substituted thiophene monomer, 3-(hexyl methacrylate)thiophene was prepared and polymerized by free radical polymerization, followed by an electrochemical polymerization. The resulting polymer as a yellow-green-light emitter, has potential applications in photoelectronics area.
