| Summary: | 碩士 === 國立中央大學 === 化學研究所 === 99 === Asymmetric fused thiophene compound (11) was synthesized by “one-pot” reaction. Based on compound (11), derivatives (1) and (2) have been developed. Both compounds exhibit p-type field-effect performances with mobility of 0.026 and 9x10-4 cm2/Vs via vacuum evaporation, respectively.
Compounds (3) ~ (9) have been successfully developed based on bithiophene compound (18). Preparation of soluble compound (18) has been improved with better yield. Compounds (6), (7), and (8) exhibit good field-effect performances with high mobility of 0.15, 0.38, and 0.24 cm2/Vs via solution process, respectively. All of these new semiconductor materials exhibit good stability under light, air, and thermal conditions.
