(Phys.org)—Researchers from Technische Universitt München in Germany hold succeeded in covalently binding porphine to the edge of a graphene sheet on a Ag(111) substrate using surface-assisted covalent coupling. This provides a proof-of-principle that graphene edges can be functionalized with tetrapyrroles in a precise manner. Furthermore, their work shows that the graphene-porphine structure maintains its electronic and metal-binding properties. Their work appears in Nature Chemistry.
