چکیده انگلیسی
Three new chemodosimeters 1–3 were prepared, and their chromogenic and fluorogenic behaviors toward various anions were investigated. Receptors 1–3 show exclusive response toward CN− ion and also distinguish CN− from other anions by different color changes in aqueous solution (EtOH/H2O = 3/7, v/v). Among them, receptor 1 selectively exhibits a pronounced CN−-induced fluorescence enhancement. Thus, the receptor 1 can be used as a colorimetric and fluorescent sensor for the determination of CN− ion. The practical use of the receptor 1 for the determination of sodium cyanide (1.5 μM) in aqueous solution was also reported.
