On exposure to certain alkaline earth metals they exhibit superconducting properties at temperatures as high as 33 Kelvin.
They behave as soft electrophiles, and three of the four valence electrons in each carbon atom are involved in the sp2 bonding skeleton, while the fourth p electron is a member of a pi-delocalized sea which covers the interior of the molecule, and forms a cloud similar to that found in graphite. On exposure to certain alkaline earth metals they exhibit superconducting properties at temperatures as high as 33 Kelvin. They can form aggegrates called graphenes, which are the basic units of carbon nanotubes. FTP, Kroto, Curl, and Smalley discovered this class of compounds, an allotrope of carbon whose most famous member is C60, named for a famous architect of geodesic domes.
