摘　　要：以5-磺基水杨酸、α-噻吩甲酰三氟丙酮为小分子配体,以溶液聚合制备的甲基丙烯酸甲酯和丙烯酸聚合物(PMMA-AA)为高分子配体,合成了铕、铽的高分子配合物.通过元素分析,紫外、红外及荧光光谱分析,对标题配合物的组成、结构进行了表征,并研究了其发光性能,结果表明,标题配合物中,Eu对Tb有很强的荧光猝灭作用,Tb对Eu有较强的荧光敏化作用,但Eu和Tb的荧光发射峰的位置基本保持不变.Rare - earth（ Eu ,Tb） polymer fluorescence complexes were synthesized using 5 - sulosalicylic acid （SSA） and a - thienyltrifluoroacetone （ HTTA ） and copolymer of acrylic and methyl methylacrylate as ligands. Their properties were characterized by means of elemental analysis, UV spectra, FTIR spectra and fluorescence spectra. Fluorescence spectra showed that the fluorescence emission of europium ions were greatly sensitized by terbium ions, while the fluorescence emission of terbium ions were strongly quenched by europium ions. On the other hand, the peak position of fluorescence emission basically keeps unchanged.
