A novel phosphorescence host material containing carbazole moiety, 1,4-bis(9-phenyl-9.H-carbazol-3-yl)benzene(l) , was synthesized by Suzuki coupling reaction of 1,4-dibromo-benzene with (9-phenyl-9H-carbazol-3-yl) boric acid. The structure was characterized by 1H NMR, 13C NMR and IR. The optoelectronic property of 1 was investigated by UV-Vis, fluorescence emission spectra and cyclic voltammetry. The results showed that 1 exhibited UV-Vis absorption and photoluminescent properties of the carbazole moiety and lower LUMO energy level than 4,4'-bis( N-carbazolyl) -1,1'-bi-phenyl.%以对二溴苯和(9-苯基)-9H-3-咔唑硼酸为原料,通过Suzuki偶联反应合成了一种新型含咔唑磷光主体材料——1,4-二[(9-苯基)-9H-3-咔唑基)]苯(1),其结构经1H NMR,13C NMR和IR表征.UV,荧光光谱和循环伏安法的光电性能研究结果表明,1具有咔唑基团的紫外-可见吸收和荧光特性,与4,4-二(9-咔唑)联苯相比,最低空轨道的能级降低.
