碩士 === 國立中央大學 === 化學研究所 === 99 === This article focuses on the development of highly stable materials for organic semiconductors. Three soluble compounds (1), (3), and (6) were synthesized. Extension of π-π conjugation and introduction of electron withdrawing group to the fused thiophene core, n-type compounds (2), (3), (4), and (7) were developed. Asymmetric fused thiophene compounds (8) and (9) as well as a symmetric compound (10) were also prepared.The OTFT devices are fabricated by two groups:Tobin J. Marks group at Northwestern University (vacuum deposition) and Industrial Technology Research Institute (solution process).Compounds (2) and (4) exhibit n-channel mobility of 0.33 and 0.37 cm2/Vs with vacuum deposition, respectively. Compounds (5) and (6) exhibit n-channel mobility of 0.08 and 0.15 cm2/Vs via solution process. Compounds (8), (9), and (10) show p-channel mobility of 0.23 cm2/Vs,7.28×10-3 cm2/Vs as well as 0.049 cm2/Vs。
