_{Fullerenes are molecules that composed entirely of carbon. They are similar in structure to graphite, which is composed of a sheet of linked hexagonal and pentagonal rings that prevent the sheet from being planar. Each carbon atom on the surface of fullerenes is bonded to three carbon neighbors, therefore, is sp2 hybridized. Fullerenes are in the form of a hollow sphere, ellipsoid, tube, and many other shapes.}

_{High purity carbon 60 fullerenes for use in thermal evaporation systems as either electron acceptors, n-type semiconductors or interface layers.}
