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]
