摘要
以噻吩甲酰三氟丙酮为第一配体,顺丁烯二酸酐、十一烯酸、油酸、丙烯腈为活性第二配体,合成了四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、荧光光谱分析,对标题配合物的组成、结构进行了表征,并研究了它们的发光性能,结果表明,四种新的反应型三元配合物具有良好的发光性能,且配合物中引入了能与其它单体共聚的活性第二配体,为合成具有优异发光性能的键合型稀土高分子功能材料提供了一条新的途径。
New four reactive ternary Europium complexes were synthesized with the first ligand of thienyltrifluoroacetone and the reactive second ligand such as maleic anhydride, acrylonitrile, undecenoic acid, oleic acid; and characterized by means of elemental analysis, EDTA titrimetric method, FT-IR spectra and UV spectra. Fluorescence spectra show that the four new ternary complexes have very strong luminescence intensity. In the same time, the reactive ternary europium complexes that have been coordinated with reactive ligands, which can be copolymerized with other monomers, will provide a new way for the synthesis of the bonding-type rare earth polymer functional materials having excellent luminescence properties.
