Iptycene Explained

An iptycene is an aromatic compound composed of varying number of arene subunits bound to a bridged bicyclo-octatriene core structure. They are formally derivatives of barrelene. The first and simplest iptycene molecule is triptycene.^[1]

The first iptycene was reported in 1931 by Erich Clar.^[2] Paul Bartlett's research group developed Clar's method and made the first triptycene.^[3] 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.^[4]
