摘　　要：在苯并三噻吩分子(BTT)基础上,经Stille反应与2-溴-3-十二烷基噻吩进行偶联,合成了新型苯并三噻吩衍生物BTT-T,产率56.8%,其结构和性能经^(1)H NMR,^(13)C NMR,MS,UV,FL,CV和TG表征。结果表明:BTT和BTT-T的光学能隙分别为3.44 eV和2.75 eV;两种分子均有较好的热稳定性。The synthesis of novel benzotrithiophene molecule(BTT-T)was reported.The intermediate organotin was synthesized based on the existing benzotrithiophene molecule(BTT),and coupled with 2-bromo-3-dodecylthiophene via Stille reaction to give a novel benzotrithiophene derivative(BTT-T)with higher degree of conjugation and stronger electron-donating ability.The yield for BTT-T was 56.8%.The structures and performances of BTT and BTT-T were characterized by ^(1)H NMR,^(13)C NMR,MS,etc.The results showed that the optical band gaps of BTT and BTT-T were 3.44 eV and 2.75 eV,respectively.Both of the molecules BTT and BTT-T showed good thermal stabilities.
