苯乙烯基三苯胺（吲哚啉）衍生物的合成及性能研究

Synthesis and Properties of Styryl Triphenylamine（ Indoline ）Derivatives

摘要:

以苯胺、咔唑、吲哚啉和碘苯等为原料，合成了五种系列化的新型苯乙烯基三苯胺（吲哚啉）类的硝基化合物，通过氢谱、高分辨质谱等对其进行了结构表征. 并对化合物的紫外-可见吸收光谱、荧光发射光谱和循环伏安等进行了研究. 结果表明，含螺旋桨构型三苯胺基团化合物相比具有平面刚性构型的9-苯基咔唑基团化合物，表现出较强的分子内电荷转移能力（ICT作用），同时在三苯胺基团上引入给电子基团则有利于增强化合物的ICT作用，而含吲哚啉基团化合物则比三苯胺基团化合物表现出更强的ICT作用

Abstract:

With aniline，carbazole，indoline and iodobenzene as raw materials，we designed and synthesized a series of five new styryl triphenylamine derivatives.The synthesis method and the yields were discussed. Combining the data of 1H NMR and MS，the molecular structures were confirmed. Moreover, the five compounds were characterized by UV-Vis absorption，fluorescence and cyclic voltammorgrams.The result showed that carbazole with flat structure possesses a weaker intramolecular charge transfer(ICT) character for triphenylamine；introducing electron-donating爂roups to triphenylamine could enhance its ICT燾haracter；Additionally，indoline was found to show a better ICT character than triphenylamine.
