showed selective and sensitive fluorometric change upon addition of a copper ion. The Np-azaCE chemosensor was highly selective for Cu2+ over the other metal ions with fluorescent quenching. Finally, the Cu2+ detection limit and job's plot of Np-azaCE were calculated using UV–visible spectrophotometer and fluorescence spectrophotometer.

In various non-hemeironoxygenases the Fe(II) center is coordinated by 2 N and 1 O atoms of the 2-His-2-carboxylate facial triad; however, most artificial model complexes bear only N-based ligands. In an effort to closely mimic the coordination environment in α-ketoglutarate dependent oxygenases, we have now employed the Me2tacnO ligand (4,7-dimethyl-1-oxa-4,7-diazacyclononane) in the synthesis of
在各种非血红素铁加氧酶中,Fe(II) 中心由 2-His-2-羧酸三联体的 2 个 N 和 1 个 O 原子配位;然而,大多数人工模型复合物仅带有 N 基配体。为了密切模拟 α-酮戊二酸依赖性加氧酶中的配位环境,我们现在在复合物的合成中使用了 Me 2 tacnO 配体(4,7-二甲基-1-oxa-4,7-二氮杂环壬烷)[( Me 2 tacnO)FeCl 2 ] 2 ( 1-NNO )、[(Me 2 tacnO)FeCl 3 ] ( 1 b-NNO ) 和 [(Me 2 tacnO)Fe(BF)Cl] ( 2-NNO; BF = 苯甲酰甲酸酯)。与涉及 Me 3 tacn的相应配合物( 1,4,7 -trimethyl-1,4,7-triazacyclononane) 配体。此外,通过停流技术,我们可以检测到2-NNO与 O 2反应中的中间体 ( 3-NNO ) 。3-NNO的光谱特征与
