利用具溶解度之三併環噻吩分別與二併環、三併環、四併環噻吩和其本身進行聚合反應，開發出 Polymer (1) ~ (4) 四種有機高分子半導體材料，期能藉由高共振系統的架構，得到較好的分子排列情形，提升元件之載子移動率。其中 Polymer (3) 利用溶液製程所得之載子移動率最高可達 7.2 x 10-4 cm2/Vs。 此外亦開發出外掛兩硫醚烷基之聯噻吩，以此為單體分別與二併環、三併環和四併環噻吩進行聚合，製備出 Polymer (5) ~ (7)。其中 Polymer (5) 以溶液製程所得之載子移動率最高可達 1.2 x 10-2 cm2/Vs 為本研究中所開發之電性表現最佳之高分子。而 Polymer (6)正進行電性之量測，期望能有不錯的電性表現。 Three polymers (1) ~ (3) based on a well-soluble DTT unit were synthesized. In addition, polymer (4) was prepared via oxidative polymerization. Via solution process, polymer (3) exhibited p-type field-effect performance with mobility of 7.2 x 10-4 cm2/Vs. Furthermore, Polymer (5) ~ (7) based on a soluble bithiophene were developed via the Stille coupling. Via solution process, polymer (5) exhibited p-type field-effect performance with mobility of 1.2 x 10-2 cm2/Vs.
