FIG. 5. — Fluorescent probes based on the nucleophilicity of H₂S_n. (a) Fluorescent probes based on nucleophilic aromatic substitution of hydrogen polysulfide with the fluorine group of the probe. (b) Highly specific fluorescent probe for hydrogen polysulfide, utilizing phenyl 2-(benzoylthio)benzoate as a recognition moiety. (c) Reversible fluorescent probe for hydropersulfide based on nucleophilic reaction of hydropersulfide with the pyronine unit of the probe. (d) Fluorescent probe for the detection of both H₂S and H₂S_n as different fluorescence signals. Gray or green star indicates nonfluorescent or strongly fluorescent molecule, respectively.
