铕(Ⅲ)—4VP光致发光稀土配合物单体的制备

Synthesizing monadic of photoluminescence with the complexes of rare earth Eu (Ⅲ)-4-VP

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。

Synthesizing the rare earth (Eu)-ternary complexes containing double bond with 4-vinyl pyredine,phen as ligand one step in alcoholic solvent.The process of photoluminescence of the complexes was discussed more fully by UV spectra and fluorescence spectra.The results show that the 4-vinyl pyredine can coordinate with rare ions directly by nitrogen atom in the pyredine ring,and the phen have cooperative coordination effect.The rare earth temary complexes have greatly fluorescence intensity.
