合成了配合物La(C4H6O2)2(hq)(C4H6O2=甲基丙烯酸,hq=8-羟基喹啉),通过元素分析、摩尔电导、红外光谱、紫外光谱和热重分析手段对产物进行表征。此外,采用紫外吸收光谱、荧光光谱,研究了配合物与鲱鱼精DNA之间的相互作用。结果显示配合物与鲱鱼精DNA作用的结合常数K=7．59×103L·mol-1,配合物与DNA的作用摩尔比为1∶1,作用模式为嵌插作用。%A ternary complex of La(Ш)with methacrylic acid and 8-hydroxyquinoline(La(C4H6O2)2(hq),C4H6O2=methacrylic acid,hq=8-hydroxyquinoline) was synthesized and characterized by elemental analysis,molar conductivity,IR spectrum,ultraviolet spectrum and differential thermal gravimetric analysis methods. In addition, the interaction between ternary complex and herring sperm DNA have been investigated by absorption spectroscopy and fluorescent spectroscopy. The results showed that the binding constant k of complex with herring sperm DNA was7. 59×103L·mol-1,and the molar ratio of 1∶1. Their interaction mode is due to insertion.
