Noun

circumcoronene (plural circumcoronenes)

(organic chemistry) An aromatic hexagonal flat sheet molecule composed of fused benzene rings, 3 benzene rings to a side, 19 rings to a sheet. An outer ring of 12 fused benzene rings surrounds the core coronene. Circumcoronene has the molecular formula C₅₄H₁₈
