Abstract
We report on the atomic structure of graphene nanoribbons (GNRs) formed via on-surface synthesis from 10,10′-dibromo-9,9′-bianthryl (DBBA) precursors on Cu(111). By means of ultrahigh vacuum noncontact atomic force microscopy with CO-functionalized tips we unveil the chiral nature of the so-formed GNRs, a structure that has been under considerable debate. Furthermore, we prove that - in this particular case - the coupling selectivity usually introduced by halogen substitution is overruled by the structural and catalytic properties of the substrate. Specifically, we show that identical chiral GNRs are obtained from 9,9′-bianthryl, the unsubstituted sister molecule of DBBA.
