A Hybrid of Corannulene and Azacorannulene: Synthesis of a Highly Curved Nitrogen-Containing Buckybowl

摘要

A highly curved nitrogen-containing buckybowl, which can be considered as a corannulene/azacorannulene hybrid, was synthesized and characterized. This molecule has a polycyclic aromatic C40N core, corresponding to a partial azafullerene structure C80-xNx (x=1,2,3...), and exhibits interesting properties that arise from its large and highly curved surface and the embedded nitrogen atom, which include association with C-60, a lower LUMO level relative to azapentabenzocorannulene, and the formation of a radical cationic species upon oxidation.
