Eu(Ⅲ)-4-酰代DPP-Phen三元配合物荧光性质讨论

STUDY ON FLUORESCENCE PROPERTIES OF TERNARY COMPLEXES OF Eu()4ACYL DPP1, 10PHENANTHROLINE

合成了４种Ｅｕ（Ⅲ）与１，３－二苯基－４－酰基－５－吡唑酮及１，１０－邻菲罗啉三元配合物，对它们的荧光性质进行了讨论．结果表明，配合物发射Ｅｕ（Ⅲ）的特征荧光；配合物的荧光强度与配体４－酰代ＤＰＰ吡唑环４－位酰基上的取代基团密切相关；第二配体１。

Four europium() ternary complexes with 1,3dipheny14acyl5pyrazolones and 1, 10phenanthroline have been prepared. Their fluoresent properties were discussed. It is indicated that the complexes emit with the characterastic fluorescence of Eu(), the fluorescence intensity of the complexes are closely related to the substituents at the acyl at 4position in pyrazolone ring of 4acyl DPP, and that the second ligand, 1, 10phenanthroline, remarkably intensifies the fluorescence of the complexes.
