稀土-异烟酰肼席夫碱配合物的设计、合成与结构

摘要

由异烟酰肼和2-吡啶甲醛合成了席夫碱配体HL并和稀土离子合成组装得一系列稀土配合物.用X-射线单晶衍射对配合物的结构进行了测定.通过荧光测试发现La配合物有荧光,而Eu,Dy则使配体的荧光淬灭.%A series of the lanthanide complexes were synthesized by the reaction of Ln3+(Ln=La, Eu and Dy) with the Schiff base HL which was prepared by the reaction of isonicotinic carboxhydrazide with 2-carboxyledyhyde pyridine.The complexes were structurally characterized by X-ray diffraction single-crystal structure analyses. The luminescence of the ligand and the lanthanide complexes were also determined. CCDC: 683448, 1; 683449, 2;683450, 3.
