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 ≈10 4 .
