铽-邻氨基苯甲酸-十一烯酸与甲基丙烯酸甲酯共聚物的合成与荧光性能研究

摘要

用铽-邻氨基苯甲酸-十一烯酸与甲基丙烯酸甲酯共聚得到含铽(Ⅲ)稀土高分子.红外和紫外光谱研究表明,共聚物主要表现为聚甲基丙烯酸甲酯的吸收,同时也体现出配体的吸收；热重分析和玻璃化转变温度表明,共聚物和高分子基质相比其热稳性提高；荧光光谱研究结果表明,共聚物的发光强度提高到配合物单体的11.53倍；回归分析预测表明,共聚物的发光强度均随配合物单体含量的增加而增大,未出现荧光猝灭现象.%The rare earth copolymers containing terbium were synthesized with terbium-o-ami-nobenzoic acid-undecylenic acid and methyl methacraylate.IR and UV-vis spectra indicate that the copolymers exhibited the absorption from polymethylmethacraylate.and also the absorption from the ligand; thermogrovimetric analysis and glass transition temperature measurement suggest that the heat stability of the copolymer was increased in comparison with polymer matrix; fluorescence spectra indicate that the luminescent intensity of the copolymer was increased to 11.53 times that of the complex monomer; regression anaysis suggests that luminescent intensity got enhanced with increase of the complex monomer content,with no fluroscence quenching.
