利用 “one-pot” reaction 開發出不對稱主體併環噻吩 (1) 與併環噻吩 (6)，並且將併環噻吩 (1) 產率提升。其併環噻吩衍生物分子 (2) ~ (5) 也已開發成功，當中分子 (2)、分子 (3) 與分子 (5) 皆為 P 型半導體材料，載子移動率分別達 0.11 cm2 / Vs、0.088 cm2 / Vs 及 0.08 cm2 / Vs，而可溶性 P 型半導體材料分子 (4) 也表現高載子移動率為 0.606 cm2 / Vs。這些不對稱併環有機半導體材料皆表現相當良好的光、空氣與熱穩定性。 Asymmetric molecules (1) and (6) were synthesized by “one-pot” reaction, and the yield of molecule (1) was improved. Four asymmetric molecules (2), (3), (4) and (5) based on molecule (1) had been developed. All of the molecules are P-type semiconductor materials. Molecule (2) exhibits good field-effect performance with a high mobility of 0.11 cm2 / Vs. In addition, the mobilities of molecule (3) and (4) are 0.088 and 0.08 cm2 / Vs. Soluble molecule (4) had been developed by attaching a long n-octyl chain to the end position and exhibits excellent field-effect performance with a mobility as high as 0.606 cm2 / Vs via solution process. These organic semiconductor materials all show good stability under photo, air and thermal conditions.
