摘　　要：通过Ullmann偶联和Suzuki偶联等反应合成了一种新型不对称咔唑衍生物9-苯基-3-[4-(9H-9-咔唑基)苯基]-9H-咔唑,其结构经1HNMR、13CNMR和FT-IR分析表征。利用紫外-可见吸收光谱、荧光光谱和循环伏安法对其光电性能进行了研究,研究结果表明,该化合物的最高占有轨道(HOMO)和最低空轨道(LUMO)能级分别为5.69和2.21 eV,具有良好的空穴传输性能。A novel unsymmetrical carbazole derivative 3-[4(9H-carbazol-9-yl) phenyl]-9-phenyl-9H-carbazole was synthesized by Ullmann coupling and Suzuki coupling reaction.The product was characterized by 1 HNMR,13 CNMR and FTIR.The optoelectronic property of the product was investigated by UV-Vis absorption spectra,fluorescence emission spectra and cyclic voltammetry.The results show that the highest occupied molecular orbital(HOMO) energy level and the lowest un occupied molecular orbital(LUMO) energy level of the product are 5.69 and 2.21 eV respectively,indicating that it has good hole transport property.
