Abstract

A novel selective fluorescent chemosensor based on naphthalimide derivatives (AN-SB) was synthesized and characterized. Once combined with Cu2+, 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-Cu2+) formed by Cu2+ 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-Cu2+, however, slight changes were observed in the presence of other anions.
