含偶氮苯8-羟基喹啉稀土配合物的合成与表征

摘要

合成了三种含偶氮苯8-羟基喹啉稀土配合物,通过元素分析、红外、紫外、荧光光谱及热分析,确定了三种配合物的组成为REL3( RE=Sm,Eu,La),三种配合物在550～650 nm都能产生荧光,峰值(λmax)分别为569,559,552 nm.%Three containing azobenzene 8-hydroxyquinoline and rare earth complexes were synthesized by elemental analysis,IR,UV, H NMR,fluorescence spectrum,and TG-DTG. The compositions of complexes were confirmed to be REL3(RE=Sm, Eu, La). Three complexes can produce fluorescence in 550 ～ 650 nm range,the peak wavelength(λmax) are 569,559,552 nm.
