摘　　要：以N-苯基-1-萘胺和对溴碘苯为起始原料,经Buchwald-Hartwing偶联反应合成有机发光二极管空穴传输材料N,N′-二[4-(1-萘基苯基氨基)苯基]-N,N′-二苯基-[1,1′-联苯]-4,4′-二胺(2)。以1-溴化萘(1-溴萘)为初始原料与N,N′-二苯基联苯二胺经Buchwald-Hartwing偶联合成了N,N′-[二(1-萘基)-N,N′-二苯基]-1,1′-联苯基)-4,4′-二胺(NPB)。利用~1HNMR、LC-MS等对产品结构进行表征。通过差示扫描量热仪(DSC)测得化合物2和NPB失重5%的温度分别为510℃和491℃,化合物2的玻璃化转变温度Tg为126℃,化合物2和NPB的升华温度分别为395℃和290℃,并通过UV-Vis紫外吸收光谱、荧光光谱研究了两种传输材料的光学性质。The organic light-emitting diode(OLED)hole transporting material N,N′-bis[4-(1-nap-hthalenylphenylamino)phenyl]-N,N′-diphenyl-[1,1′-biphenyl]-4,4′-diamine(2)was synthesized by a Buchwald-Hartwing coupling reaction using 1-naphthylaminobenzene and pbromoiodobenzene as starting materials.NPB was synthesized by coupling Buchwald-Hartwing with 1-bromonaphthalene as starting material and N,N′-diphenylbiphenyldiamine.Structure of compounds was confirmed by^1HNMR and LC-MS.The temperature at which 5%weight loss of compound 2 and NPB was measured by differential scanning calorimetry was 510℃and 491℃,respectively.The glass transition temperature Tg of compound 2 was 126℃and the sublimation temperature of compound 2 and NPB were 395℃and 290℃,respectively.The optical properties of the two hole transporting materials were investigated by UV-Vis ultraviolet absorption spectroscopy and fluorescence spectroscopy.
