Circumcoronene is a polycyclic aromatic hydrocarbon with the molecular formula C54H18. It consists of a central coronene molecule circumscribed by benzene on the periphery.

Circumcoronene is the third benzenoid hydrocarbon in the benzene-coronene-circumcoronene series. It comes after benzene and coronene, and is followed by circumcircumcoronene. Various topological and mathematical properties have been computed for molecules in this series.[1][2]

On-surface synthesis of circumcoronene was achieved in 2021 via intramolecular dehydrogenation of a precursor hexa-peri-hexabenzocoronene, followed by methyl radical coupling and aromatization, on a Cu(111) surface.[3] A solution-phase synthesis was reported in 2023 via acid-mediated cyclization of alkynes, confirmed via X-ray crystallographic analysis and NMR measurement.[4]
