Abstract
•New salicylaldehyde based fluorescent sensor 1 was designed.•Sensor 1 displayed ‘turn on’ fluorescence for biologically important fluoride ion.•ESPT was responsible for the fluoride-induced fluorescence enhancement.
A novel and simple salicylaldehyde based anion fluorescent sensor 1 has been designed, which can selectively sense fluoride by ‘turn on’ excited-state intermolecular proton transfer (ESPT). The binding constant and the stoichiometry were obtained by non-linear least-square analysis of the titration curves.
