A “naked eye” and ratiometric fluorescent chemosensor for rapid detection of F− based on combination of desilylation reaction and excited-state proton transfer

Abstract

A colorimetric and ratiometric fluorescent chemosensor for F(-) has been prepared, which is based on combination of desilylation reaction and excited-state proton transfer from the desilylation product to F(-). The sensor exhibits rapid response, excellent selectivity and sensitivity to F(-).
