The Molecular Hall of Phane




On the left is the X-ray structure of pyreno[4,5-c;9,10-c’]difuran.  This was used to make the molecule on the right, a pyrenophane.  It’s an example of a cyclophane:  molecules that have a flat aromatic portion linked across the ring by an aliphatic chain.  These were prepared by David Franz; X-ray structures by Steve Robbins and René Boeré.
