摘　　要：以甲基丙烯酸为第一配体、邻菲罗啉为第二配体、铕离子为中心离子,合成一种可聚合稀土荧光配合物单体,通过元素测试、FT-IR对其组成、结构进行分析,证明配合物中含有能够进行聚合反应的双键,并确定其结构式为Eu(MAA)3Phen.通过TGA和溶解性测试对配合物性能进行研究,结果表明:配合物具有良好的热稳定性,初始分解温度达到297℃;配合物溶解性能良好,可溶于常见极性溶剂.采用荧光分光光度计测试配合物的荧光性能,结果表明其具有较高的荧光强度和色纯度,可作为一种高效的稀土红光材料.A novel polyrnerizable rare earth complex was synthesized with Eu3＋, methacrylic acid （MAA）, and 1,10-phenanthroline（Phen）, using absolute ethyl alcohol as solvent. The chemical structure was determined as Eu（MAA）a （Phen） by elemental analysis. Afterwards, it was characterized by means of FT-IR, the results revealed that the complex contained double bonds and it was polymerizable. The performances of the complex were characterized by solubility testing and TGA. The results indicated that the complex had high solubility in common polar solvents and exhibited excellent thermal stability. In addition, the complex was characterized by fluorescence spectroscopy, and it was found that the complex exhibited marked luminescence at the wavelength of 594 nm and 619 nm.
