以4,4'-联萘胺为母体,以最常用的空穴传输材料N,N'-二(α-萘基)-N,N'-二苯基-4,4'-联苯胺(α-NPD)为样板,合成了新型空穴传输材料N,N'-二(α-萘基)-N,N'-二苯基-4,4'-联萘胺(α-NPN).通过核磁共振氢谱和元素分析进行了结构表征.差热分析测定其玻璃化温度(Tg)达到128 ℃.相对于α-NPD,α-NPN的吸收光谱和光致发光光谱都发生了红移.循环伏安法测定其氧化电势为1.20V,比α-NPD的1.02V稍高.该化合物可发明亮的蓝色荧光 (461 nm),积分球测定其薄膜荧光量子效率为8.5%,比α-NPD的5.5%高.初步确定α-NPN可作为有机电致发光空穴传输材料.
