本研究延續實驗室之併環噻吩開發，製備出具有高穩定性有機半導體材料 (1) ~ (13)；引入長碳鏈與拉電子基於併環噻吩主體，開發出可溶性 n-type 的有機化合物 (11) ~ (13)。目前，有機化合物 (11) 與有機化合物 (13) 以溶液製程製成元件，已得不錯的 n 型電性表現，載子移動率高達 0.10 與 0.26 cm2/Vs；有機化合物 (2) 以溶液製程製成元件，也有不錯的 p 型電性表現，載子移動率高達 0.03 cm2/Vs。其他有機半導體材料仍在待測中。Thirteen soluble and highly stable fused thiophene (DTT and TTA) based materials (1-13) have been developed for organic thin film transistors (OTFT). Via extension of π-π conjugation and introduction of electron withdrawing group (C6F5) to these fused thiophene cores, three n-type compounds (11; DFPTT-DTTR), (12; DFPbT-DTTR), and (13; DFPTT-TTAR) have been newly obtained. Via solution process, the OTFT devices are fabricated by Industrial Technology Research Institute. Markedly, DFPTT-DTTR (11) and DFPTT-TTAR (13) exhibit n-channel mobilities of 0.10 and 0.26 cm2/Vs via solution process, respectively.
