Abstract

We report the application of a range of chemical reactions to the basal plane functionalization of graphene, including the Diels-Alder reaction – in which we show that graphene can act as both diene and dienophile – and the addition of nitrophenyl radicals. The chemical formation of covalent carbon-carbon bonds involving the basal plane carbon atoms offers an alternative approach to the control of the electronic properties of graphene; the transformation of the carbon centers from sp2 to sp3 introduces a barrier to electron flow by saturating the carbon atoms and opening a band gap which potentially allows the generation of insulating and semiconducting regions in graphene wafers. In this talk I will discuss our work on the electronic and magnetic properties of chemically modified graphene.
