Investigation on the photophysical properties of ESPT inspired salicylaldehyde-based sensor for fluoride sensing
چکیده انگلیسی


• A simple, highly selective and sensitive chemosensor QP has been developed.
• Sensor QP exhibited fluorescence enhancement for biologically important fluoride ion.
• ESPT resulted in the fluoride-triggered ‘turn on’ fluorescence.

A simple, highly selective and sensitive chemosensor (E)-2-((quinolin-8-ylimino) methyl) phenol (QP) has been developed for the fluoride, as demonstrated by the photophysical properties obtained by UV–vis and fluorescent methods. Excited-state inter/intramolecular proton transfer (ESPT) was suggested to be responsible for the fluoride-induced ‘turn on’ fluorescence and the blue shift of 25 nm in the emission spectrum.
