Synthesis and Optical Properties of 1-(4-pyridin-2-yl)phenyl3,5-di[4-(9′H-carbazol-9′-yl)phenyl]benzene

以咔唑、对二溴苯、4-溴苯胺和1,3,5-三溴苯为原料,经重氮化、Ullmann反应、硼酸化和Suzuki等反应合成了一种新型的荧光配体———1-(4-吡啶基)苯基-3,5-二[4-(9'H-9'-咔唑基)苯基]苯(6),其结构经1H NMR,MS和元素分析表征。研究了6在二氯甲烷中的紫外吸收光谱和荧光光谱。结果表明,6在237 nm,293 nm和345 nm处有较强吸收;6的最大发射波长在413 nm。

A novel phosphorescent ligand,1-（4-pyridin-2-yl）phenyl-3,5-di[4-（9′H-carbazol-9′-yl）phenyl]benzene（6）,was synthesized by diazotization,Ullmann reaction,boronic acidification reaction and Suzuki coupling reaction from carbazole,1,4-dibrombenzene,4-bromobenzenamine and 1,3,5-tribromobenzene.The structure was characterized by 1H NMR,MS and elemental analysis.The UV-Vis and fluorescence spectra of 6 in dichlorom ethane were investigated.The results showed that λmax of 6 were 237 nm,293 nm and 345 nm.λem was 413 nm.
