The cyclopropanation reaction involving them is called the Bingel reaction.  
In 1999, researchers from the University of Vienna proved that these macromolecules demonstrate wave-particle duality.  The cyclopropanation reaction involving them is called the Bingel reaction.  Most reactions involving them take place at 6,6-double bonds, and the endohedral varieties containing three atoms of terbium cause them to become egg-shaped and violate the isolated pentagon rule.  Most often forming nanotubes or icosahedrons, FTP, identify this family of molecules that are carbon allotropes and named after a famous architect.
