Synthesis and luminescent properties of ternary complexes of terbium with thenoyltrifluoroacetone and reactive ligand

Three new reactive ternary terbium complexes were synthesized with the first ligand of thenoyltrifluoroacetone and the reactive secondary ligand such as maleic anhydride, undecenoic acid, oleic acid, and characterized by means of elemental analysis, ethylenediamine tetraacetic acid titrimetric method, Fourier transform infrared and ultraviolet spectroscopies. And the luminescent properties of the ternary terbium complexes were investigated.The results show that the ternary terbium complexes possess much higher luminescent intensity than the binary complex of terbium with thenoyltrifluoroacetone, and the synergy ability sequence of the three reactive ligands is as follows: undecenoic acid＞oleic acid＞maleic anhydride. Because the ternary terbium complexes contain reactive ligands that can be copolymerized with other monomers, a new way for the synthesis of the bonding-type rare earth polymer functional materials with excellent luminescent properties is provided.     

铽芳香羧酸丙烯酰胺三元配合物的合成及发光性能研究

以对甲基苯甲酸、对氨基苯甲酸、磺基水杨酸、大茴香酸、水杨酸为第一配体,丙烯酰胺为活性配体,合成了五种新的铽芳香羧酸丙烯酰胺三元配合物。通过元素分析,EDTA配位滴定分析,热分析,红外、紫外、荧光光谱分析对目标配合物的组成、结构进行了表征,并研究了它们的发光性能。结果表明,五种新的活性铽三元配合物均具有良好的发光性能,各芳香羧酸向铽离子传递光能的能力为:大茴香酸>磺基水杨酸>对氨基苯甲酸>对甲基苯甲酸>水杨酸,将这些含活性配体丙烯酰胺的铽发光配合物引入高分子化合物中可望合成出键合型铽高分子发光材料。
