摘要

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 mu M) in aqueous solution was also reported.
