【摘要】 以吡啶和溴苯为原料,通过Chichibabin反应、溴代、重氮化溴化、Suzuki偶联等一系列反应,合成了标题化合物。此一系列的反应,条件较温和,中间体和产物提纯简单,并且都有较高的产率。通过元素分析、核磁共振氢谱对其结构进行了确认,并测得其在二氯甲烷溶液中的紫外吸收光谱和荧光光谱。更多还原

【Abstract】 Using pyridine and 4-bromoaniline as basic materials,a novel phosphorescent ligand 2,5-di[4’-(9H-carbazol-9-yl)phenyl]pyridine was synthesized through the Chichibabin reaction,bromosubstitution,diazotization and bromination of aminogroup,the Suzuki crossing reaction and other reactions.The structure of the target compound was confirmed by elementary analysis and nuclear magnetic resonance spectroscopy.The ultraviolet and visible spectroscopy,and the fluorescent spectroscopy of this compound in dichloromethane solution were also studied.更多还原
