Olympicene Chemical Structure

This is the chemical structure for olympicene.
This is the chemical structure for olympicene. Todd Helmenstine

The chemical formula for olympicene is C19H11.

Olympicene is an organic compound made up of five rings which join together to form the shape of the Olympic rings. The molecule was developed by Graham Richards at the University of Oxford together with Antony Williams. David Fox and Anish Mistry at the University of Warwick were the first to actually synthesize the molecule.

Olympicene was designed as a way to celebrate the 2012 London Olympics.

The rings of olympicene are not interlinked, so it has been proposed that a better Olympic molecule would be olympiadane, which is made of interlocking catenanes. Olympiadane was synthesized in 1994 by Fraser Stoddart.
