A novel selective fluorescent chemosensor based on naphthalimide derivatives (AN-SB) was synthesized and characterized. Once combined with Cu(2+), compound AN-SB could give rise to a visible yellow to orange color change and fluorescence quenching, while other metal ions showed subtle disturbance. The complex (AN-SB-Cu(2+)) formed by Cu(2+) and AN-SB displayed high specificity for H2PO4(-). Among the various anions, only H2PO4(-) induced the revival of color and fluorescence of AN-SB, resulting in "off-on" type sensing of H2PO4(-) anion. The signal transduction occured via reversible formation-separation of complex AN-SB-Cu(2+), however, slight changes were observed in the presence of other anions.
一种基于萘酰亚胺衍生物的新型选择性荧光化学传感器（AN-SB）被合成并进行了表征。一旦与 Cu(2+) 结合，化合物 AN-SB 会引起可见的黄色到橙色颜色变化和荧光猝灭，而其他金属离子则显示出细微的干扰。由 Cu(2+) 和 AN-SB 形成的配合物（AN-SB-Cu(2+)）对 H2PO4(-) 显示出高特异性。在各种阴离子中，只有 H2PO4(-) 能引起 AN-SB 的颜色和荧光恢复，从而对 H2PO4(-) 阴离子进行“关-开”型传感。信号转导通过配合物 AN-SB-Cu(2+) 的可逆形成-分离发生，然而，在存在其他阴离子时，仅观察到轻微的变化。
