We show the strategy of introducing azobenzene groups into graphene nanoribbons (GNRs), which not only endows GNRs with fast photo-responsiveness but also induces the self-assembly of the GNRs into ultra-long nanowires.
Large quantities of nitrogen-doped graphene nanoribbons can be synthesized via Yamamoto coupling of molecular precursors followed by cyclodehydrogenation using Scholl reaction.
