Well-defined, fused-ring aromatic compounds are promising candidates for the fundamental understanding and application of advanced carbon-rich materials, though bottom-up synthesis and structure–property correlation of these compounds remain challenging. Dynamic bond formation represents an ideal strategy to construct such extended molecules with high efficiency. Here I present two examples of using this strategy to construct aromatic systems containing up to 13 fused rings. In the first example, dynamic ring-closing olefin metathesis is employed to construct extended benzo[k]tetraphene-derived oligomers. In the second example, non-covalent N—B coordination bond is incorporated into conjugated system to render highly coplanar, low bandgap, extended pi-system. The optoelectronic properties and crystallization dynamics of these compounds were investigated and correlated with their unique constitutional structures.
