Twelve heteroaromatic complexing agents 9a–I were synthesized with the purpose to develop suitable labels for time-resolved luminescence-based bioaffinity assays. The relative luminescence yields, excitation maxima, and emission decay constants of their europium(III) and terbium(III) chelates were determined. According to these results, 2,2′,2″,2‴-[(2,2′-bipyridine-6,6′-diyl)bis(methylenenitrilo)]tetrakis
合成了十二种杂芳族络合剂9a–I,目的是为基于时间分辨的发光的生物亲和力分析开发合适的标记。确定了它们的euro(III)和ter(III)螯合物的相对发光产率,激发最大值和发射衰减常数。根据这些结果,2,2',2'',2‴-[(2,2'-联吡啶-6,6'-二基)双(亚甲基腈)]四(乙酸)(9e)和2,2' ,2″,2′-[(2,2′:6′,2″-叔吡啶-6,6″-二基)双(亚甲基腈)]四(乙酸)(91)是最有前途的试剂。
