ⓘ Circulene

A circulene is a macrocyclic arene in which a central polygon is completely surrounded and fused by benzenoids. Nomenclature within this class of molecules is based on the number of benzene rings surrounding the core, which is equivalent to the size of the central polygon. Examples which have been synthesized include circulene has a unique saddle-shaped structure. The helicenes are a conceptually related class of structures in which the array of benzene rings form an open helix rather than a closed ring.

                                     
  • Kekulene is a polycyclic aromatic hydrocarbon and a circulene with the chemical formula C48H24. It was first synthesized in 1978, and was named in honor
  • K min from 328 K to 298 K over a period of 12 hours. Coronene is a planar circulene It forms needle - like crystals with a monoclinic, herringbone - like structure
