We present the first example of covalent chemistry on fluorographene , enabling the attachment of –SH groups through nucleophilic substitution of fluorine in a polar solvent. The resulting thiographene‐like, 2D derivative is hydrophilic with semiconducting properties and bandgap between 1 and 2 eV depending on F/SH ratio. Thiofluorographene is applied in DNA biosensing by electrochemical impedance spectroscopy.
