A ,water,-soluble fluorescent probe (C-GGH) was used for the highly sensitive and selective detection of cyanide (CN −) in aqueous media based on the displacement strategy. Due to the presence of the recognition unit GGH (Gly-Gly-His), the probe C -GGH can coordinate with Cu 2+ and consequently display ON-OFF type fluorescence response.
