以 4 乙烯基吡啶 (4VP)、邻菲洛啉 (Phen)为配体 ,与EuCl3 在乙醇溶液中一步合成了含有双键的三元稀土配合物 ,通过紫外光谱与荧光光谱的测定 ,研究稀土配合物光致发光的机理。结果表明 ,4 乙烯基吡啶通过吡啶环上的氮原子与稀土离子可直接配位 ;邻菲洛啉配体具有协同配位效应。稀土配合物较EuCl3 的荧光发射强度提高了 12倍之多。
The ternary rare earth complexes containing double bonds were synthesized by the reaction of 4-vinylpyridine (4VP) and phenanthroline (Phen) as ligand with EuCl3 in ethanol solution. The effects of rare earth Complex photoluminescence mechanism. The results showed that 4-vinylpyridine could directly coordinate with the rare earth ions through the nitrogen atom of the pyridine ring, and the coordination phenanthroline ligand had synergistic coordination effect. Rare Earth complexes EuCl3 fluorescence emission intensity increased by 12 times.
