During the last decade, on‐surface fabricated graphene nanoribbons (GNRs) have gathered enormous attention due to their semiconducting π‐conjugated nature and atomically precise structure. A significant breakthrough is the recent fabrication of nanoporous graphene (NPG) as a 2D array of laterally bonded GNRs. This covalent integration of GNRs could enable complex electronic functionality at the nanoscale; however, for that, it is crucial to externally control the electronic coupling between GNRs within NPGs, which, to date, has not been possible. Using quantum chemical calculations and large‐scale transport simulations, this study demonstrates that such control is enabled in a newly designed quinone‐NPG (q‐NPG) thanks to its GNRs inter‐connections based on electroactive para‐benzoquinone units. As a result, the spatial distribution of injected currents in q‐NPG may be tuned, with sub‐nanometer …
