The insertion of metal atoms and heteroaromatic units provides a way to tune the optical, electronic and magnetic properties of graphene nanoribbons. Now the synthesis of a porphyrin-fused graphene nanoribbon with a narrow bandgap and high charge mobility has been achieved, and this material used to fabricate field-effect and single-electron transistors.
