  • Patent number: 11644414
    Abstract: The present disclosure relates to a ferrocene-based compound having high selectivity for sulfide ion. The ferrocene-based compound is obtained by reacting a ferrocene starting material with one or more organic compound selected from a nitrile, a methyl ester and an ethyl ester, and a chemical sensor in solution state is prepared by mixing the compound with an organic solvent. The chemical sensor according to the present disclosure has high selectivity and sensitivity for sulfide ion even at low concentration and may be used as a chemical sensor for detecting hydrogen sulfide in solution state by allowing visual inspection of sulfide ion.
