Abstract

Visual detection: cyclo-Bis(urea-3,6-dichlorocarbazole) (1), the first anion receptor bearing urea, displays a fluorescence quenching effect with pyrophosphate and fluoride ions. Its deprotonated form (12−) acts as a new fluorescent probe that can selectively detect metal cations (Zn2+ and Cu2+) by means of colorimetric changes.
