| 摘 要： | 用先络合再聚合和先聚合再络合的方法,合成了稀土高分子铕(Eu)-邻菲罗啉(Phen)-丙烯酸(AA)-甲基丙烯酸甲酯(MMA)。用红外光谱和X射线衍射测试方法对其结构和物相进行了分析,表明铕与高分子基质发生配位。比较二者的荧光性质,发现得到的配位聚合物是一种良好的光致发光材料,在紫外光下发出亮度和单色性高的特征红色荧光,但当配位聚合物中铕离子(Eu3+)的质量分数达1.97%时,第二种方法合成的聚合物发生浓度猝灭现象。

| Abstract: | In this investigation,the rare earth europium polymers Euphenanthroline-acrylic acid-methyl methacrylate were prepared by two different methods.One was complexation followed by polymerization,while another was the contrary.As characterized by FTIR and XRD,coordination was happened between europium and the polymer matrix.The fluorescence spectra demonstrated that these polymers were a kind of good photoluminescent materials and emitted characteristic red fluorescence with high brightness and good monochromaticity under UV irradiation.Concentration quenching phenomenon was found in the polymers prepared from the second method when the mass fraction of europium ion reached 1.97%. |
