title: The ferrocene-pyrylium dyad as a selective colorimetric chemodosimeter for the toxic cyanide and hydrogen sulfide anions in water.
abstract: The ferrocene-pyrylium dyad behaves as a selective redox and colorimetric chemodosimeter for CN(-) and HS(-) anions, exhibiting a clear perturbation in the redox potential of the ferrocene unit and in the absorption band, in the presence of these anions.
