以二芳胺和3,5-二甲基碘苯为原料,利用乌尔曼(Ullmann)反应,合成出了4个结构不对称三芳胺衍生物1～4,除了化合物1之外均为新化合物.利用IR,1H NMR,13C NMR,HRMS和元素分析对其结构进行了表征.考察了它们的光学、电化学和热稳定性质.实验结果表明,所合成的4个目标化合物在氯仿稀溶液中发出绿色荧光,具有良好的电化学和热稳定性.所合成的目标化合物是潜在的空穴传输材料及发绿光的材料.
Using diarylamine and 3,5-dimethyliodobenzene as raw materials, four structurally asymmetric triarylamine derivatives 1 ~ 4 were synthesized by Ullmann reaction, all of which were new except compound 1 Their structures were characterized by IR, 1H NMR, 13C NMR, HRMS and elemental analysis. Their optical, electrochemical and thermal stability properties were investigated. The experimental results show that the four target compounds synthesized in dilute chloroform Emits green fluorescence and has good electrochemical and thermal stability.The synthesized target compounds are potential hole transporting materials and green emitting materials.
