Heteroatoms in Bowl-shaped Polycyclic Aromatic Hydrocarbons: Synthesis and Structures

Nowadays, exploring the chemistry of curved π-conjugated molecules is one of the big trends in organic chemistry. Recently, research interests have been shifted to heteroatom containing analogs. Among these, bowl-shaped π-conjugated molecules with heteroatoms included within their skeletons have gained interest due to their synthetic difficulty and have been developed dramatically as a motif for heteroatom-doped carbon materials. Here, this review highlights analogs based on polycyclic aromatic hydrocarbons, represented by triangulenes, sumanenes and corannulenes, with heteroatoms. These studies have disclosed the effect of heteroatoms in curved π-surfaces. Nowadays, chemistry of curved π-conjugated molecules is one of the big trends in organic chemistry.
