“…The image clearly reveals the straight 7-AGNR structure corresponding to the nanoribbon formation on Au(111) 1 in contrast to the growth of partially chiral nanoribbons from DBBA on Cu(111). 17 We tentatively attribute this behavior to: (1) a vertical relaxation of Au atoms of the surface layer above the Cu atoms, 37 exposing them more for Ullmann coupling reactions, and (2) a signicant enrichment of the surface layer by Au atoms compared to the ideal Cu 3 Au(111) surface. 30 In addition to pristine 7-AGNRs, we also observe the spontaneous growth of defective ribbons (Fig.…”
The on-surface synthesis of nano-graphenes has led the charge in prototyping structures with perspectives beyond silicon-based technology. Following reports of open-shell systems in graphene-nanoribbons (GNR), a flurry of research activities...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
