利用甲基丙烯酸甲酯（MMA）、水杨酸（SA）与硝酸铕（Eu（NO3）3）反应,合成了Eu-MMA-SA三元稀土配合物,然后以此铕配合物为单体,以偶氮二异丁腈（AIBN）为引发剂,在一定条件下进行聚合反应,制备铕-聚甲基丙烯酸甲酯-水杨酸（Eu-PMMA-SA）无机-高分子多元光功能杂化材料,红外光谱（FT-IR）分析结果表明,Eu3＋离子与水杨酸和甲基丙烯酸甲酯中的羧酸根配位;凝胶渗透色谱（GPC）结果分析说明,聚合物的数均分子量（-Mn）,重均分子量（-Mw）和多分散系数（PDI）值分别为12000,19000和1.58;荧光光谱分析结果证明此杂化材料具有很强的铕离子特征荧光。
The ternary rare earth complex europium-methyl methacrylate –salicylic acid（Eu-MMA-SA） was synthesized via the reaction of the MMA,SA and the Eu（NO3）3.Following,the europium-poly（methyl methacrylate）-salicylic acid（Eu-PMMA-SA） organic-polymer hybrid materials with optical-functional were prepared using Eu-MMA-SA as the monomer and 2,2′-azobis（2-methylpropionitrile）（AIBN） as the initiator at given conditions.Fourier transform infrared spectroscopy（FT-IR） results indicated that the COO-of salicylic acid and MMA complexe with Tb3＋;Gel permeation chromatographer（GPC） result shows that the n,w and PDI of the polymer is 12000,19000 and 1.58 respectively;The luminescence spectroscopy analysis proves that the hybrid materials can send strong fluorescence properties of the europium ion.
