The fast and the fluoride: A pyridine derivative functionalized with tert-butyldimethylsilyl ether has been synthesized and used as a selective chromofluorogenic fluoride sensor in water/cetyltrimethylammonium bromide solutions. The chromofluorogenic response arises from the fluoride-induced hydrolysis of the silyl ether moiety, which generates a coloured and highly emissive phenolate anion.
