摘要：

The external efficiency of poly(3-(2-(5-chlorobenzotriazolo)ethyl)thiophene) (PCBET) containing electron transporting moiety was 1.2 x 10(-4) %. To enhance the efficiency of PCBET, we have synthesized polythiophene derivatives by introducing an alkoxy group which raises the HOMO and decreases the band gap due to the electron-donating nature of the oxygen.
