The luminescence properties of a series of lanthanoid cryptates with an increasing number of 2,2'-bipyridine units have been investigated for the lanthanoids Eu and Tb in aqueous solution. The trends in important parameters that influence the photophysics in these complexes have been determined. With increasing bipyridine content, an increase is observed for the intersystem crossing efficiencies and the number of inner-sphere water molecules. In contrast, a decrease is found in the same direction for overall quantum yields, triplet energies, and sensitization efficiencies.
研究了一系列镧系元素密胺配合物的发光性质，这些配合物中 2,2'-联吡啶单元的数量逐渐增加，涉及镧系元素 Eu 和 Tb 在水溶液中的情况。确定了影响这些配合物光物理性质的重要参数的趋势。随着联吡啶含量的增加，观察到体系间交叉效率和内球水分子数量的增加。相比之下，整体量子产率、三重态能量和敏化效率则朝着相反的方向下降。
