A pyrylium-coumarin dyad as a colorimetric receptor for ratiometric detection of cyanide anions by two absorption bands in the visible region

We synthesized a pyrylium-coumarin dyad (1) and used it for colorimetric detection of cyanide anions (CN-) in aqueous media. The receptor itself exhibits a long-wavelength absorption band at 643 nm due to the strong intramolecular charge transf
