反应型三元铽配合物的合成及发光性能研究

Synthesis and Luminescence Properties of Reactive Ternary Terbium Complexes

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、亚油酸为活性第二配体,合成了5种新的反应型三元铽配合物。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,五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,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 five reactive ternary terbium complexes were synthesized with the first ligand of 1,10-phenanthroline and the second reactive ligand such as maleic anhydride, acrylonitrile, undecenoic acid, oleic acid and linoleic acid, and characterized by means of elemental analysis, EDTA titrimetric method, FT-IR spectra and UV spectra. Fluorescence spectra show that the five new ternary complexes have much higher luminescence intensity than their binary complexes. In the same time, the reactive ternary terbium complexes that have been coordinated with the 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, which will have nice luminescence properties.
