合成了一个新型配体,2-甲基-6-(8-喹啉基)-吡啶二甲酸酯(L),并制备和表征了其的Tb(III)配合物, Na4Tb(L)2Cl4·3H2O。荧光光谱显示配体L是一个有效的敏化稀土离子发光的配体。 Stern-Volmer分析显示荧光猝灭机制为静态猝灭。结合常数研究证明其只有一个结合位点。
閤成瞭一箇新型配體,2-甲基-6-(8-喹啉基)-吡啶二甲痠酯(L),併製備和錶徵瞭其的Tb(III)配閤物, Na4Tb(L)2Cl4·3H2O。熒光光譜顯示配體L是一箇有效的敏化稀土離子髮光的配體。 Stern-Volmer分析顯示熒光猝滅機製為靜態猝滅。結閤常數研究證明其隻有一箇結閤位點。

A novel ligand, 2-methyl -6 -(8 -quinolinyl) -dicarboxylate pyridine (L), and its corresponding Tb(III) complex, Na4Tb(L)2Cl4 · 3H2O, was successfully prepared and characterized.The luminescence spectra showed that the ligand L was an efficient sensitizer for Tb ( III) luminescence.The Stern-Volmer analysis indicated that the fluorescence quenching of BSA by Na 4Tb(L)2Cl4· 3H2O was resulted from static mechanism.The binding sites (n) approximates 1.0 and this meant that interaction of Na4Tb(L)2Cl4· 3H2O with BSA had single binding site.
