The atomically precise on-surface synthesis of carbon-based nanostructures is of relevance for electronic and optoelectronic devices, but achieving control over such architectures remains challenging. Here, the authors demonstrate the selective stepwise on-surface synthesis of nitrogen-doped porous carbon nanoribbons with well-defined topologies and structures, and predict variable band gaps dependent on ribbon width.
