In this work, 4-(p-hydroxybenzylidenehydrazino)-N-butyl-1,8-naphthalimide (1) has been designed and synthesized as a colorimetric and fluorescent dual-modal probe for F-. Compound 1 immediately detected inorganic fluoride salts using UV/vis absorption and fluorescence spectroscopy methods, and served as a naked-eye' indicator for F- with high selectivity and sensitivity. Both the absorption and fluorescence spectra show excellent linearity with the concentration of F-. Real-life applications demonstrated that our proposed analytical system provided a satisfactory method for the determination of F-. In addition, the reaction mechanism of deprotonation was confirmed by H-1 NMR.
