摘要
在温和的反应条件下,以2,4-二氟苯硼酸、2-氯喹啉为原料合成了一种新型离子型铱配合物,通过元素分析、红外光谱、1H-NMR、质谱以及X单晶衍射对产物进行了结构表征。并考察了配合物的光物理性能和热稳定性能。结果表明配合物单晶结构为扭曲的八面体构型,属于三斜晶系,空间群为P-1;配合物最大发射波长为542nm,CIEx,y坐标为(0.41,0.57),是一种新型的黄色发光的离子型铱磷光配合物。
A novel ionic iridium complex was synthesized under mild condition with 2,4-difluorophenylboronicacid, 2-chloroquinoline. The complex was characterized by elemental analysis, IR, 1 H-NMR,MS(ESI) and X-ray diffraction(XRD). Its light-physical properties and the thermal stability of the complex were investigated. The single crystal structure of the complex is adopting twisted octahedral coordination mode, in triclinic and space group P-1. The novel ionic iridium complex produces a strong photoluminescence at 542 nm and CIEx, y coordinates of(0.41, 0.57).
