Fabrication of Chemical Graphene Nanoribbons via Edge‐Selective Covalent Modification

Chemical graphene nanoribbons (CGNRs), a new type of quantum-confinement graphene nanostructure with tunable electrical conduction channels and bandgaps, are fabricated by chemically narrowing the conduction channels of the graphene based on an edge-selective covalent reaction. Such CGNRs behave as semiconductors with tunable on/off ratios ranging from a few hundreds to ≈104.
