摘　　要：以咔唑为起始原料,经Ullmann反应,NBS亲电取代反应和Buchwald-Hartwig偶联反应合成了一种新型的含芴咔唑类空穴传输材料——N,N'-二(联苯-4-基)-N,N'-二(9,9-二甲基-2-芴基)-9-苯基咔唑-3,6-二胺(4),其结构经1H NMR,13C NMR,IR和MS表征。用DSC-TG,UV-Vis和荧光光谱研究了4的热稳定性和光学性能。结果表明,4失重5%的温度为507℃,玻璃化温度为179℃;在380 nm波长的激发下,4的最大发射波长在448 nm。A novel hole -transporting material, N, N＇ -di [ （ 1, 1＇-biphenyl ） -4 -yl ] -N, N＇-bis （ 9,9-dime- thylfluoren-2-yl） -9-phenyl-gH-carbazole-3,6-diamine （ 4 ）, was synthesized by Ullmann reaction, NBS electrophonic substitution reaction and Buchwald-Hartwig coupling reaction from carbazole. The structure was characterized by 1H NMR, 13C NMR, IR and MS. Thermal properties and optical prop- erties of 4 were investigated by DSC-TG, UV-Vis and PL. The results showed that 5% weight loss temperature and the glass transition temperature of 4 is 507℃ and 179 ℃, respectively. The maxi- mum peak of 4 is at 448 nm under 380 nm excitation.
