Chemodosimeter for fluoride ions based on F−-triggered Si–O cleavage followed by the deprotonation/autoxidation of secondary nitrile C–H group

Abstract

A completely new strategy for a chemodosimeter for fluoride based on F⁻-triggered Si–O bond cleavage, followed by the deprotonation/autoxidation of secondary nitrile C–H group was developed for the first time. The chemodosimeter exhibited high selectivity and sensitivity, dramatic color “turn-on”, and fluorescence “turn-off” for the detection for fluoride.
