Abstract
A well‐rounded radical: A stable corannulene‐based neutral radical with curved π conjugation was synthesized, and the crystal structure was determined. Unbalanced delocalized electronic spin on the three‐dimensional π surface of the corannulene moiety (see spin‐density distribution) demonstrates a sizable intermolecular exchange interaction and curved aromaticity.Keywords
