摘　　要：文章以邻菲咯啉为第一配体 ,顺丁烯二酸酐、丙烯腈、十一烯酸、油酸和亚油酸为活性第二配体 ,合成了 5种新的反应型三元铕配合物。通过元素分析 ,EDTA配位滴定分析 ,红外、紫外和荧光光谱分析 ,对标题配合物的组成和结构进行了表征 ,并研究了它们的发光性能。结果表明 ,5种新的反应型三元配合物与相应的二元配合物相比发光强度大大提高 ,反应型配体产生“协同效应”的能力为 :亚油酸 >油酸 >丙烯腈 >顺丁烯二酸酐 >十一烯酸。且配合物中引入了能与其他单体共聚的活性第二配体 。In this paper, five new reactive ternary europium complexes were synthesized with the first ligand of 1,10-phenanthroline and the reactive second ligands of maleic anhydride, acrylonitrile, undecenoic acid, oleic acid and linoleic acid, and also characterized by means of elemental analysis, EDTA titrimetric method, FTIR spectra and UV spectra. The fluorescence spectra show that the five new ternary complexes have much higher luminescence intensity than their corresponding binary complexes, and the synergy ability sequence of the five reactive ligands is as follows: linoleic acid > oleic acid > acrylonitrile > maleic anhydride > undecenoic acid. At the same time, the reactive ternary europium complexes coordinated with the reactive ligands, which can be copolymerized with other monomers, will provide a new way for the synthesis of bonding-type rare earth polymer functional materials with excellent luminescence properties.
