摘要

合成了三个以含氟苯基吡啶及吡啶基咪唑为配体的蓝色磷光电致发光铱配合物(

)

Ir(pym)

其中主配体(

)分别为2-(2'

4'-二氟苯基)-4-甲基吡啶、2-(3'

5'-二氟苯基)-4-甲基吡啶;辅助配体pymH为2-(2'-吡啶基)咪唑。通过元素分析、核磁、质谱、红外进行结构表征;用紫外可见吸收光谱、荧光光谱以及循环伏安进行其光谱学性能表征。以pymH取代辅助配体picH(2-吡啶甲酸)的方法

得到含吡啶基咪唑的铱配合物

在室温下二氯甲烷溶液中获得强的蓝光发射

其最大发光波长分别是461

480

490 nm

其中(46f

pmpy)

Ir(pym)较经典蓝光磷光材料FIrpic蓝移5 nm。
