Abstract

arbon-rich  materials  such  as  fullerenes, carbon nanotubes, and graphene  have  a  wide  range  of  unusual physical properties resulting from their unique topography. For example, graphene, a two-dimensional sheet material consisting solely of carbon atoms, is a zero-gap semiconductor (1). When this same  material  is  rolled  into  a  cylindrical topology a  carbon  nanotube the  resulting material can be either metallic or semiconducting, depending on the specific atom connectivity. Many other molecular entities can  be  synthesized  entirely  from  carbon (2).  On  page  272  of  this  issue,  Segawa  et al.  (3)  report  the  synthesis  of  nanocarbons that  are  mechanically  interlocked.  These mechanically  bound  nanocarbons  create  a  bridge between carbon nanoscience and research into molecular machines.
