Interchain-linked graphene nanoribbons from dibenzo[g,p]chrysene via two-zone chemical vapor deposition

Abstract

We report covalently interchain-linked graphene nanoribbons fabricated on Au(111) by a stepwise growth process via two-zone chemical vapor deposition. Prepolymer arrays were grown by surface-assisted polymerization of a precursor, 1,9-dibromodi-benzo[g,p]chrysene at 250 °C. Further annealing at 450 °C converted the prepolymers into interchain-linked graphene nanoribbons via intramolecular and intermolecular dehydrogenation reactions.
