Triptycene

Triptycenes are a class of aromatic hydrocarbons. The parent compound triptycene is the Diels-Alder reaction product of anthracene and benzyne. The compound has a paddlewheel configuration with D3h symmetry. The hydrocarbon framework is very rigid and is therefore incorporated in many organic compounds as a molecular scaffold for instance in molecular motors. Barrelenes are conceptually related compounds.
