%X Although several porous carbon/graphene nanorib-bons (GNRs) have been prepared, a direct comparison of theelectronic properties between a nonporous GNR and itsperiodically perforated counterpart is still missing. Here, we reportthe synthesis of porous 12-atom-wide armchair-edged GNRs froma bromoarene precursor on a Au(111) surface via hierarchicalUllmann and dehydrogenative coupling. The selective formation ofporous 12-GNRs was achieved through thermodynamic andkinetic reaction control combined with tailored precursor design.The structure and electronic properties of the porous 12-GNRwere elucidated by scanning tunneling microscopy/spectroscopyand density functional theory calculations, revealing that the poresinduce a 2.17 eV band gap increase compared to the nonporous12-AGNR on the same surface.
