本篇論文主要的研究重點在於合成出兩種系統之新的有機半導體材料，第一種系統是以 NDT (1) 和 NFDT (4) 為架構，合成出 DP-NDT (2)、DFP-NDT (3)、DOP-NDT (7)、DP-NFDT (5) 以及DFP-NFDT (6) 共五種有機半導體材料。第二種系統是利用 “one-pot” reaction 開發出不對稱主體併環噻吩BTTTT 做為架構，合成出了P-BTTTT (8)、TMS-BTTTT (9)、O-BTTTT (10)、BTBTTT (11) 共四種有機半導體材料。第三種系統是以BTT 為架構，合成出 BBTT (12)、BT-BTT (13)、P-BTT (14) 共三種有機半導體材料。第四種系統是以 ADT 為架構，合成出 TES-ADT (15)、DiF-TESADT (16)、BTPE-ADT (17) 共三種可溶性有機半導體材料。 所有半導體材料元件製作的部分，由西北大學Tobin J. Marks實驗室協助製作，以上所合成出的有機半導體目前使用溶劑製程與真空蒸鍍的方法來製作元件當中。目前這些新的OTFT材料的元件製備條件仍在嘗試階段，希望能找出最適合的製程條件，以期提昇載子移動率並製作出元件效能更佳的有機薄膜電晶體。 Two new organic semiconductor material systems were investigated. The first system is based on NDT (1) and NFDT (4), five new organic semiconductor materials: DP-NDT (2), DFP-NDT (3), DOP-NDT (7), DP-NFDT (5), and DFP-NFDT (6) were synthesized. The second system is based on asymmetric molecule BTTTT, four new organic semiconductor materials: P-BTTTT (8), TMS-BTTTT (9), O-BTTTT (10), BTBTTT (11) were synthesized by “one-pot” reaction. The third system is based on BBT, three new organic semiconductor materials: BBTT (12)、BT-BTT (13), and P-BTT (14) were synthesized. The forth system is based on ADT, three new organic semiconductor materials: TES-ADT (15)、DiF-TESADT (16), and BTPE-ADT (17) were synthesized. The devices fabrication of all the materials are currently assisted by Tobin J. Marks group at Northwestern University, where the solution process and vacuum deposition will be examined. Hopefully, better mobilities and easier fabrication will be obtained in the future.
