2-Hydroxy-1-naphthaldehyde (receptor 1) serves as a selective chemosensor for cyanide anion (CN-). In the presence of CN-, an enhanced fluorescent intensity and red shift were observed. The observed complexation between receptor 1 and CN- may cause from a formation of phenoxide anion by nucleophilic addition of the CN- to carbonyl group.
