Abstract:	本研究以 BDT 為單元，開發出新的 n-type 小分子有機薄膜電晶體材料 (OTFT)，藉由核心結構苯並二噻吩（BDT）的共軛平面性和剛性結構，使其有效改善能階差並增加吸收波段，具有高遷移率的 n-type 小分子材料。為了增加 BDT 核心系統的溶解度，在核心外側引入不同長度的醚鏈，合成出三種新型可溶性小分子材料 : BDTQ-6、BDTQ-10、BDTQ-14。利用 UV-vis 和 DPV 來分別探討 BDTQ系列在不同醚鍊長度的光學和電化學性質，並藉由熱重分析儀 (TGA) 來研究其熱穩定性性質。;A new series of organic optoelectronic materials were synthesized and characterized for n-type organic thin-film transistor (OTFT) application. Three novel n-type small molecules, BDTQ-14, BDTQ-10, and BDTQ-6, were synthesized and characterized. The planar conjugation and rigid structure of benzodithiophene (BDT) make it attractive for achieving highly tuneable molecular energy level and optical bandgap as well as high mobilities device. Different alkyl chain has been used to increase the solubility of BDTQ series. The optical and electrochemical properties of BDTQ series were characterized by UV-Vis and DPV. Thermal properties were investigated by TGA.
