Nanoporous graphene networks could transform electronics and spintronics

Built through bottom-up on-surface synthesis, this approach enables atomic precision in assembling carbon nanoarchitectures, offering tunable electronic and magnetic properties. While GNRs have long been central to nanoelectronics due to their semiconducting and π-conjugated characteristics, NPGs extend their functionality by providing an intrinsic platform to regulate electronic coupling between adjacent ribbons. This feature allows for the controlled emergence of quantum anisotropy, where electrical conduction varies according to direction.

A recent review by researchers at the Catalan Institute of Nanoscience and Nanotechnology (ICN2) and the Universitu of Barcelona provides an overview of an emerging class of carbon nanomaterials: nanoporous graphenes (NPGs). The work highlights how these structures, conceived as two-dimensional arrays of laterally bonded graphene nanoribbons (GNRs), could transform the future of nanoelectronics and spintronics.Built through bottom-up on-surface synthesis, this approach enables atomic precision in assembling carbon nanoarchitectures, offering tunable electronic and magnetic properties.
