以4-甲氧羰基-2-苯基喹啉为环金属配体,N^N辅助配体为解离配体合成了一系列离子型环金属铱配合物.配合物的结构通过质谱、核磁进行了表征.配合物1还测试了其单晶结构.对配合物的紫外、磷光性质进行了表征,溶液状态下为红光发射,波长在610～620 nm之间,磷光寿命在133～496 ns之间,量子效率在0.7%～16.6%之间.铱配合物的电化学发光与23Ru(bpy)+有所不同,发光电位比23Ru(bpy)+要高,且大部分铱配合物在正负电位都能发光,最大发光强度是23Ru(bpy)+的三倍.
A series of ionic ring metal iridium complexes were synthesized by using 4-methoxycarbonyl-2-phenylquinoline as ring metal ligand and N ^ N auxiliary ligand as dissociation ligand.The structures of the complexes were characterized by MS, NMR The complex was also tested for its single crystal structure.The UV and phosphorescence properties of the complex were characterized by red emission at the wavelength of 610-620 nm and phosphorescence lifetime of 133-496 ns, the quantum efficiency is between 0.7% and 16.6% .The electrochemical luminescence of iridium complexes is different from that of 23Ru (bpy) +, and the emission potential is higher than that of 23Ru (bpy) +, and most of the iridium complexes Both positive and negative potentials can emit light, the maximum luminous intensity is three times the 23Ru (bpy) +.
