title: Turn on ESPT: novel salicylaldehyde based sensor for biological important fluoride sensing.
abstract: 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.
