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。
Styryltriphenylamine compounds are considered to be a kind of hole transport luminescent materials with promising development and practical value. They have excellent overall properties such as good film-forming property, good thermal stability and the like. A novel triphenylamine aromatic conjugated system molecule, 4- [2- (1-styryl)] - N, is synthesized from triphenylamine via Welsmere reaction, N-bis (4-bromophenyl) aniline. The addition of styryl enhances the molecular conjugation effect and enhances the electron transport ability. The substitution of bromine atom will improve its solubility and enhance the thermal stability of the material, resulting in a very promising triphenylamine derivative with good photoelectric properties.
