A colorimetric and turn-on fluorescent probe 1 bearing triphenylamine-thiophene and dicyanovinyl groups has been synthesized and used to detect cyanide anion via a nucleophilic addition reaction. Probe 1 exhibited prominent selectivity and sensitivity towards CN- in aqueous media, even in the presence of other anions such as S2-, HS-, SO₃2-, S₂O₃2-, S₂O₈2-, I-, Br-, Cl-, F-, NO₂-, N₃-, SO₄2-, SCN-, HCO₃-, CO₃2- and AcO-. Moreover, a low detection limit (LOD, 51 nM) was observed. In addition, good cell membrane permeability and low cytotoxicity to HeLa cells were also observed, suggesting its promising potential in bio-imaging.
