摘要
采用Suzuki偶合、傅-克酰基化反应合成3种新化合物:(Ⅰ)3,7-双噻吩基二苯并噻吩砜、(Ⅱ)3,7-双(5-乙酰基噻吩)二苯并噻吩砜、(Ⅲ)3,7-双(对三氟甲基苯基)二苯并噻吩砜;并利用核磁共振氢谱(1H NMR)和碳谱(13C NMR)及元素分析方法表征结构,研究3化合物膜及溶液的光学性质。结果显示:新化合物分子具有C2对称性;3,7-双(5-乙酰基噻吩)二苯并噻吩砜在不同溶剂中存在溶剂化效应,其膜的荧光光谱出现非常明显的红移现象。
Three new materials, 3,7-bisthienyl dibenzothiophene S, S-dioxide, 3,7-bis （5-acetylthienyl） dibenzothiophene S,S-dioxide and 3,7-bis（trifluoromethylphenyl） dibenzothiophene S, S-dioxide, were synthesized by Suzuki coupling and Friedel-Crafts reaction, and characterized by 1H and 13C NMR spectra and elemental analysis method. The optical properties of these materials in solution and as films were studied. The result shows that these new compounds have C2 symmetry and display different optical behaviors. 3,7- Bis（5-aeetyhhienyl） dibenzothiophene S,S-dioxide displays drastic solvent effect, and its film fluorescence spectrum is red-shifted more than 100 nm as compared with that in solution.
