Abstract:	本篇論文主要的研究重點在於合成出兩種系統之新的可溶性有機半導體材料，第一種系統是以anthradithiophene (ADT)為架構，合成出5,11-dithien-2-ylanthradithiophene (DTADT)、5,11-bis(5-carbaldehydethien-2-yl)anthradithiophene (BATADT)、以及5,11-bis(5-carbaldbutylaminothien-2-yl)anthradithiophene (BBTADT) 共三種有機半導體材料。第二種系統是以p-terphenyl diamine (TDA)為架構，合成出了N,N’-bis[(5-butyl-2-thienyl)methylene]-p-terphenyl diamine (BTTDA)、N,N’-bis[(5-triethylsilyl-2-thienyl)methylene]-p-terphenyl diamine (TES-TTDA)兩種有機半導體材料。BATADT擁有拉電子的醛基在中間的噻吩上，如此可增強整個分子結構的穩定性，目前所得其載子移動率為2.1x10-5 cm2/Vs，開關電流比約為104，起始電壓為-31V，為一P型半導體材料。所有五種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，以上所合成出的可溶性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 soluble organic semiconductor material systems were investigated. The first system is based on anthradithiophene (ADT), three new organic semiconductor materials: 5,11-dithien-2-ylanthradithiophene (DTADT), 5,11-bis(5-carbaldehydethien-2-yl)anthradithiophene (BATADT), and 5,11-bis(5-carbaldbutylaminothien-2-yl)anthradithiophene (BBTADT) were synthesized. The second system is based on p-terphenyl diamine (TDA), two new organic semiconductor materials: N,N’-bis[(5-butyl-2-thienyl)methylene]-p-terphenyl diamine (BTTDA), and N,N’-bis[(5-triethylsilyl-2-thienyl)methylene]-p-terphenyl diamine (TES-TTDA) were prepared. BATADT with an electron withdrawing aldehyde functional group on the central thiophene shows the stability enhancement and demonstrates a p-type character with current mobility of 2.1x10-5 cm2/Vs, on/off ratio ~ 104 and threshold voltage -31V. The devices fabrication of all the five 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.
