Selective and fast : A flavylium derivative‐based ratiometric fluorescent probe ( 1 ) for H 2 S is reported. The reaction mechanism (see scheme) is based on the nucleophilic addition of H 2 S towards the electrically positive benzopyrylium moiety of 1 , which can efficiently differentiate H 2 S from other competitive species. The probe exhibits a fast response toward H 2 S, within 10 s, which is superior to most of the reported H 2 S probes.
