A new chromogenic and fluorescent ‘‘turn-on“ chemodosimeter 3 was designed and synthesized by using a fluoride-sensitive self-immolative linker, in combination with the fluorescent dyes 7-hydroxy-4-trifluoromethyl coumarin. The chemodosimeter exhibited high selectivity and sensitivity toward fluoride anions through ‘‘turn-on” chromogenic and fluorogenic dual modes.
