A new chemodosimeter based on pyridinium-fused pyridinone iodide (PI) has been obtained through a “clean reaction” method. This compound can detect CN− in aqueous solution with a high selectivity and rapid response. The detection of CN− occurs through the nucleophilic attack of CN− on the C[DOUBLE B...
