三芳胺类空穴传输材料的合成及光电性能

以3,5-二甲基苯胺为原料与苯磺酸钠反应合成了3,5-二甲基二苯胺,研究了反应温度、时间以及反应物配比对收率的影响,确定了最佳工艺条件。再以3,5-二甲基二苯胺与4,4'-二碘联苯通过Ullmann缩合反应合成了空穴传输材料N,N′-双(3,5-二甲基苯基)-N,N′-二苯基-1,1′-联苯-4,4′-二胺,产品收率为82.24%,经提纯,产品纯度可达99.31%。对该化合物进行的光电测试结果表明,其具有优异的空穴传输性能。

Synthesis of a Triarylamine Compound as Hole Transport Material and Its Photoelectric Performance

In this paper,3,5-dimethyldiphenylamine was firstly prepared by 3,5-dimethylaniline and benzenesulfonic acid sodium salt and the influence of temperature,time and the proportion of reactant on the yield of product were discussed.Then 3,5-dimethyldiphenylamine was reacted with 4,4′-diiodobiphenyl via Ulmann reaction to get N,N′-bis(3,5-dimethylphenyl)-N,N′-diphenyl-1,1′-biphenyl]-4,4′-diamine,as hole transport material,in yield of 82.24% and in purity of 99.31%.The photoelectric test results of the device showed that the compound had good performance of hole transport.
