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−. [ABSTRACT FROM AUTHOR]
