Abstract: Graphene nanoribbons (GNRs), quasi-one-dimensional graphene nanostructures, are promising candidates for next-generation electronic, optoelectronic, and spintronic applications due to their tunable (opto-)electronic and magnetic properties. The intrinsic properties of GNRs are critically determined by atomic-scale structural parameters such as width, edge configuration, and backbone architecture, all of which can be precisely designed and regulated through bottom-up synthetic strategies. Recent years have witnessed remarkable progress in the bottom-up chemical synthesis of GNRs, and a diverse array of innovative structural engineering strategies, such as edge topology modulation, backbone modification, and heterojunction construction, have been developed. These advances have enabled precise control over GNR characteristics and have deepened understanding of their structure–property relationships, correlating atomic-scale features with electronic band structure, charge-carrier mobility, spin polarization, and topological states. This review summarizes the latest developments of precision GNRs, focusing on how rational design and synthetic breakthroughs have transformed GNRs into a versatile, atomically precise materials platform. By integrating advanced synthesis and characterization methods, the research field is paving the way for functional GNR-based devices in future electronic, spintronic, and quantum information systems.
