Graphene nanoribbons (GNRs) hold significant promise for optoelectronic applications, but their development is hampered by the limitations of traditional iterative synthetic methods. These methods often involve complex and expensive starting materials, restricting structural and functional diversity. This hinders the rapid exploration of structure-property relationships, especially lengthdependent properties of GNRs, and the discovery of highperformance materials. A more efficient approach is to employ a modular "shotgun" synthesis, using end blocks, link blocks, and functional blocks as key components. This strategy allows for the facile synthesis of GNRs with a wide range of structures and functionalities by simply varying the functional block. we have demonstrated a highly efficient "shotgun" synthetic approach for sulfur-doped GNRs featuring a unique cove-armchair-fjord edge combination. Notably, sulfur incorporation into the backbone yielded arc-shaped GNRs. The unambiguous crystallographic characterization of AR-11 and ARO-11 reveals that the combined cove and fjord edge structure causes it to deviate from planarity due to steric repulsion. By oxidizing the electron-rich sulfur atoms to electrondeficient sulfones, we effectively tune the electronic properties of GNRs. Expanding the GNR family further, we're currently exploring the versatility of shotgun synthesis by crafting GNRs adorned with diverse heteroatom dopants.
