An amidine based chemosensor AM-1 was synthesized and characterized by various spectroscopic (FT-IR, (1)H-NMR and mass) data and elemental analyses. Sensor AM-1 exhibited high selectivity and sensitivity towards Fe(3+), Fe(2+) and Cu(2+) in the presence of other surveyed ions (such as Sr(2+), Cr(3+), Co(2+), Ni(2+), Zn(2+), Ag(+), Al(3+), Ba(2+), Ca(2+), Cd(2+), Cs(+), Hg(2+), K(+), Li(+), Mg(2+), Mn(2+), Na(+) and Pb(2+)) with a distinct naked-eye detectable color change and a shift in the absorption band. Moreover, the emission of AM-1 was quenched selectively only in the presence of Fe(3+).
合成了一种基于脒的化学传感器AM-1，并通过各种光谱（傅里叶变换红外光谱、核磁共振氢谱和质谱）数据及元素分析对其进行了表征。在存在其他被测离子（如锶离子、铬离子、钴离子、镍离子、锌离子、银离子、铝离子、钡离子、钙离子、镉离子、铯离子、汞离子、钾离子、锂离子、镁离子、锰离子、钠离子和铅离子）的情况下，传感器AM-1对铁离子（Fe(3+)）、亚铁离子（Fe(2+)）和铜离子（Cu(2+)）表现出高选择性和高灵敏度，伴有明显的肉眼可检测到的颜色变化以及吸收带的位移。此外，仅在铁离子（Fe(3+)）存在时，AM-1的发射才会被选择性猝灭。
