Based on 8-hydroxyquinoline, a 1,8-naphthalimide-derived calorimetric and fluorescent probe was synthesized for naked-eye and fluorescent recognition of F- (from both tetrabutylammonium fluoride and NaF) with high sensitivity and excellent selectivity. The probe can be employed to detect F- quantitatively within certain concentration range, and the detection limit could be as low as 1.8 mu M for tetrabutylammonium fluoride and 9 mu M for NaF. With this probe, the tests for fluorine contents in tap water, water sample from Eyebrow Lake and several brands of toothpastes were successfully performed.
