4-[2-(1-苯乙烯基)]-N,N-二(4-溴苯基)苯胺的合成研究

Synthesis of 4-[2-(1-Styrene)]-N,N-bis(4-bromophenyl) Aniline

苯乙烯基三苯胺化合物被认为是很有开发前景和实用价值的一类空穴传输发光材料,它具有较为优异的综合性能,如良好的成膜性,较好的热稳定性等。以三苯胺为原料,经维尔斯迈尔反应,溴化,维蒂希反应合成一种新颖的三苯胺类芳香共轭体系分子即4-[2-(1-苯乙烯基)]-N,N-二(4-溴苯基)苯胺。苯乙烯基的加入,使分子共轭效应增强,电子传输能力更强。溴原子的取代会使其溶解性得到改善,同时增强材料的热稳定性,得到一种非常有潜力,光电性能好的三苯胺衍生物。

The triphenyl amine derivatives are one of the most promising blue OLED materials with excellent comprehensive properties,such as good film forming ability and high thermal stability.With using it as raw material,the 4-[2-（1-styrene）]-N,N-bis（4-bromophenyl） aniline is synthesized by Vilsmeier reaction,bromination and Wittig reactions.The molecular conjugation,electron transportation is enhanced by introducing styryl.The substitution of bromine atom improves the solubility,and reinforces the thermal stability of material.A kind of triphenyl amine derivatives with potential and good photoelectric property is obtained.
