Abstract
A method of preparing functionalized graphene, comprises treating graphene with an alkali metal in the presence of an electron transfer agent and coordinating solvent, and adding a functionalizing compound. The method further includes quenching unreacted alkali metal by addition of a protic medium, and isolating the functionalized graphene.
