An iptycene is an aromatic compound composed of varying number of

arene Aromatic compounds, also known as "mono- and polycyclic aromatic hydrocarbons", are organic compounds containing one or more aromatic rings. The parent member of aromatic compounds is benzene. The word "aromatic" originates from the past grouping ...

subunits bound to a bridged bicyclo-octatriene core structure. They are formally derivatives of

barrelene Barrelene is a bicyclic organic compound with chemical formula C8H8 and systematic name bicyclo .2.2cta-2,5,7-triene. First synthesized and described by Howard Zimmerman in 1960, the name derives from the resemblance to a barrel, with the staves b ...

. The first and simplest iptycene molecule is triptycene. The first iptycene was reported in 1931 by

Erich Clar Erich Clar (23 August 1902 in Hřensko – 27 March 1987 in Estepona) was an Austrian organic chemist who studied polycyclic aromatic hydrocarbon chemistry. He is considered as the father of that field. In 1941, he authored "Aromatische Kohlenwasser ...

. Paul Bartlett's research group developed Clar's method and made the first triptycene. Following Bertlett's work on triptycene, Hart et al., with acknowledgement to Professor Joel F. Liebman, proposed the trivial name ''iptycene'' for this class of molecules.
