| has gloss | eng: Helicenes in organic chemistry are ortho-condensed polycyclic aromatic compounds in which benzene rings or other aromatic compounds are angularly annulated so as to give helically shaped molecules. The chemistry of helicenes has attracted continuing attention because of their unique structural, spectral, and optical features. |

| has gloss | nld: Helicenen zijn in de organische chemie verbindingen met in hun molecule ortho-verknoopte benzeenringen. Hiermee vallen deze verbindingen onder de polycyclische aromatische koolwaterstoffen. De verbindingen zijn vernoemd naar de helix die gevormd wordt door met name de verbindingen met 6 en meer ringen. De chemie van deze verbindingen trekt de aandacht door hun unieke combinatie van structurele, spectroscopische en optische eigenschappen. |
