Abstract

Abstract : Atomically precise chevron graphene nanoribbons can be epitaxially grown on Cu(111) substrates along the 〈112〉 crystallographic directions. Abstract : Atomically precise chevron graphene nanoribbons (GNRs) have been synthesized on Cu(111) substrates by the surface-assisted coupling of 6, 11-dibromo-1, 2, 3, 4-tetraphenyltriphenylene (C42 Br2 H26 ) and thermal cyclodehydrogenation of the resulting polymer. The GNRs form on Cu(111) epitaxially along the 〈112〉 crystallographic directions, which was found to be in agreement with the computational results, and at lower temperatures than on Au(111). This work demonstrates that the substrate plays an important role in the on-surface synthesis of GNRs and can result in new assembly modes of GNR structures.
