86:. A fullerene is any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes are also called buckyballs, and they resemble the balls used in football (soccer). Fullerenes are similar in structure to graphite, which is composed of stacked graphene sheets of linked hexagonal rings; but they may also contain pentagonal (or sometimes heptagonal) rings. 47:), predicted to be harder than diamond. Besides the pioneering work of a couple of academic groups, this class of compounds has so far garnered little attention from the broader fullerene research community. Many properties and structures are yet to be discovered for the highly-nitrogen substituted subset of molecules. 93:. The derivatives were formed in the gap between two graphite rods connected to an electric power supply. A small air leak led to contamination of the inert atmosphere and the subsequent reaction. The materials can also be formed by chemical reactions on 252:

molecule was calculated to be an insulator, with the eight all-carbon rings forming regions of extended electron delocalization.
