摘　　要：以二芳胺和芳碘体系为原料,经乌尔曼反应制备了一系列三芳胺衍生物,经NMR,IR,MS等表征了其结构,通过示差扫描量热法(DSC)测定了其玻璃化转变温度,并利用循环伏安法结合紫外可见光谱测定了其HOMO能级和LUMO能级.A series of triarylamine derivatives, which can be used as hole transport materials, have been prepared by Ullmann coupling of diarylamines and aryl iodide, catalyzed by cuprous chloride and 1,10-phenanthroline. Their structures and thermal properties were characterized by NMR, IR, MS and DSC. The HOMO energy levels of these compounds were obtained from cyclic voltammetry, based on the values of -4.8 V for ferrocene （Fc） with respect to zero vacuum level. The LUMO energy levels were obtained from the HOMO energy levels together with the UV spetra.
