稀土-异烟酰肼席夫碱配合物的设计、合成与结构(英文)

Lanthanide-isonicotinic Carboxhydrazone Schiff Base Complex: Design, Synthesis and Luminescent Property

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 Ln^3＋ （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.
