This allows a Michael\u2010type adduct formation for the detection of cyanide ions. The probe shows a remarkable color change from red to colorless upon addition of the cyanide ions in pure water. The cyanide ion reacts with the probe and removes the conjugation of the bis\u2010indolyl moiety of the probe with that of the 4\u2010substituted aromatic ring. This renders the probe colorless.
