活性铽三元荧光配合物的合成、表征及性能研究

本文以对甲基苯甲酸、对氨基苯甲酸、磺基水杨酸、大茴香酸、间氯苯甲酸为第一配体,丙烯腈为活性配体,合成了五种新的铽芳香羧酸丙烯腈三元配合物。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动力为:大茴香酸>对甲基苯甲酸>间氯苯甲酸>磺基水杨酸>对氨基苯甲酸,将这些含活性配体丙烯腈的发光铽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。

Synthesis, characterization and properties of reactive ternary fluorescence complexes of terbium

Five ternary complexes have been synthesized from terbium with aromatic carboxylic acid(p-methylbenzoic acid,p-aminobenzoic acid,sulfosalicylic acid,methoxybenzoic acid,m-chlorobenzoic acid)and acrylonitrile and aslo characterized by means of elemental analysis,thermal analysis,FT-IR spectra and UV spectra.Fluorescence spectra show five ternary complexes have nice luminescent properties.The order of ability in which the aromatic carboxylic acids transfer light energy to terbium ion is as follows:methoxybenzoic acid>p-methylbenzoic acid>m-chlorobenzoic acid>sulfosalicy lic acid>p-aminobenzoic acid.At the same time,the ternary terbium complexes containing a reactive ligand acrylonitile will possibly have potential application on the fabrication of bonding-type terbium polymer luminescent materials.
