Rare earth (Eu)-polymer ternary complexes were synthesized using copolymer of 4-vinyl pyridine-methyl acrylate as ligand, and using phen and bipy as coordination ligand. The compositions of the complexes were characterized by FTIR and elemental analysis. The photophysical process of photoluminescence of the complexes were characterized by FTIR and elemental analysis. The photophysical process of photoluminescence of the complexes was discussed more fully by UV spectra and fluorescence spectra. The experiment result shows that the copolymer of 4-vinyl pyridine can coordinate into rare ions directly by nitrogen atom in the pyridine ring. When small ligand reacts with coordination, the fluorescence intensity of the complexes increases greatly because of stronger intermolecular energy transfer.
以4-乙烯基吡啶-丙烯酸甲酯共聚物为配体，邻菲罗啉和联吡啶为配位配体，合成了稀土（铕）-聚合物三元配合物。通过傅里叶变换红外光谱（FTIR）和元素分析对配合物的组成进行了表征。通过FTIR和元素分析对配合物光致发光的光物理过程进行了表征。通过紫外光谱和荧光光谱更全面地讨论了配合物光致发光的光物理过程。实验结果表明，4-乙烯基吡啶共聚物可以通过吡啶环中的氮原子直接与稀土离子配位。当小分子配体与配位体反应时，由于更强的分子间能量转移，配合物的荧光强度大大增加。
