Single‐layer graphene stabilization : An efficient methodology to make stable aqueous solutions of single‐layer graphene has been demonstrated by exploiting charge‐transfer interactions with a coronene tetracarboxylate acceptor molecule (see figure). Microscopic studies reveal exfoliation of few‐layer graphene and selective stabilization of single‐layer graphene in large quantities.
