Based on 1,8-naphthalimide, a novel multifunctional colorimetric and fluorescent probe was designed and synthesized for basic pH and F- naked-eye and fluorescence recognition with high sensitivity and excellent selectivity. The probe can detect F- quantitatively in a concentration range of 0-16.7 mu M and 0-20 mu M in different methods, and the detection limit could be as low as 25 nM for F-. The detection of F- on chromatography plates and the preliminary application of the probe to detect fluoride contents in toothpaste have been successfully demonstrated.
