Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Organometallic hexahapto (η⁶)‐chromium metal complexation of single‐layer graphene</bold>, which involves constructive rehybridization of the graphene π‐system with the vacant chromium d_π orbital, leads to field effect devices which retain a high degree of the mobility with enhanced on‐off ratio. This η⁶ mode of bonding is quite distinct from the modification in electronic structure induced by conventional covalent σ‐bond formation with creation of sp³ carbon centers in graphene lattice and this chemistry is reversible. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg1ts4zhzg" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
