Thiofluorographene-hydrophilic graphene derivative with semiconducting and genosensing properties

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 de...

Description
Summary: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.
