Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500094-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>We present the first example of covalent chemistry on fluorographene</bold>, 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. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjg4ptwz1" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
