A highly selective colorimetric and turn-on fluorescent probe for cyanide anion

A new colorimetric and turn-on fluorescence selectivity in the presence of other anions in tributed to the interruption of pi-conjugation a dicyanoethylene unit. chemosensor was developed for cyanide anion with high an aqueous THF solution. The sensing mechanism is attributed a nucleophilic addition of cyanide to the beta-position of (C) 2012 Elsevier Ltd. All rights reserved.
