A turn on fluorescent sensor for cyanide based on ICT off in aqueous and its application for bioimaging

- A colorimetric and “turn-on” fluorescent chemosensor based on a hybrid coumarin-hemicyanine dye for cyanide was synthesized.
- The detection can be realized in quasi-aqueous phase and the detection limit of probe for CN− was found to be 0.066 μM.
- Its practical application was proved by bioimaging.
