稀土-烟酸-8-羟基喹啉三元配合物合成、表征及其抑菌活性

Synthesis,Characterization and Research on Bioactivity of Ternary Complexes of Rare Earth with Nicotinic Acid and 8-Hydroxyquinoline

在有机溶剂中合成了 4种未见报道的稀土、8 羟基喹啉和烟酸三元固体配合物 ,并运用元素分析、摩尔电导、红外光谱、紫外和荧光光谱、热分析等手段进行表征。将合成的固体三元配合物进行了抑菌试验 ,并与稀土离子、配位等对比 ,其结果表明配合物对真菌有一定的抑制作用。

Four kinds of new ternary complexes of rare earth with nicotinic acid and 8 hyoxyquinoline were synthesized in organic solution,and characterized by elemental analysis,molar conductivity,infrared spectra,ultraviolet absorption spectra and fluorescence spectra and thermal analysis.By comparing ternary complexes of rare earth with the bioactivity of rare earth ion,ligand and binary complexes,it is found that ternary complexes of rare earth,which is worth further research and spreading has fungistatic ability.
