A naphthalimide-based highlyselectivecolorimetric and ratiometric fluorescent probe for the fluorideion displayed both one- and two-photon ratiometric changes. Upon reaction with the F− (TBA+ and Na+ salts) anion in CH3CN as well as in aqueous buffer solution, probe 1 shows dramatic color changes from colorless to jade-green and remarkable ratiometric fluorescence enhancements signals. These properties
