Fusible Conducting Poly(9-alkylfluorene) and Poly(9,9-dialkylfluorene) and Their Characteristics

Conducting poly(9-alkylfluorene) and poly(9,9-dialkylfluorene) with long alkyl chains have been prepared and found to be fusible at relatively low temperature. Unlike in poly(3-alkylthiophene), electrical conductivity and band gap energy do not change remarkably at the solid-liquid phase transition. These polymers also demonstrate drastic changes of optical and electrical properties upon doping.
