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 synthesi zed with terbium-o-aminobenzoic acid-undecylenic acid and methyl methacraylate.IR and UV-vis spectra indicate that the copolymers exhibited the absorption f rom 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;fluore scence spectra indicate that the luminescent intensity of the copolymer was increase d to 11.53 times that of the complex monomer;regression anaysis suggests that l uminescent intensity got enhanced with increase of the complex monomer content,with no f luroscence quenching.
