碩士 === 國立中山大學 === 化學系研究所 === 106 === Polythiophene is a conductive polymer. By modifying different functional groups in the β position of thiophene, the properties of the polymer can be altered. Since the photoelectric performance of the polythiophene is also excellent after doping, these have some applications like organic solar cells, organic electroluminescence display and other organic photoelectric materials. Common synthetic methods of polythiophene include: chemical oxidation by FeCl3, catalytic coupling reaction by transition metal or electrochemical polymerization. This thesis focus on the development of ROMP for the synthesis of polythiophene. Thiophene derivatives and alkynes were used to synthesize bridged heterocyclic derivatives by Diels-Alder reaction, the bridged heterocyclic monomers were then polymerized by ROMP followed by oxidation to produce polythiophene. In addition, the synthesis of polypyrrole by ROMP was also attempted.
