Fullerin sarupa bentukna jeung struktur grafit, nu diwangun ku salambar cingcin héxagonal numbu, tapi cingcinnna péntagonal (atawa kadang héptagonal) nu nyegah lambaranana jadi planar. Fullerin nyolobong mindengna disebut tabungnano (nanotubes). The smallest fullerene in which no two pentagons share an edge (which is destabilizing — see pentalene) is C60 (buckminsterfullerene), and as such it is also the most common.
The structure of C60 is that of a truncated icosahedron, which resembles a round soccerball of the type made of hexagons and pentagons, with a carbon atom at the corners of each hexagon and a bond along each edge. A polymerized single-walled nanotubule (P-SWNT) is a substance composed of polymerized fullerenes in which carbon atoms from one buckytube bond with carbons in other buckytubes.
Until the late twentieth century, graphite and diamond were the only known allotropes of carbon. Then, in molecular beam experiments, discrete peaks were observed corresponding to molecules with the exact mass of 60, 70, or greater numbers of carbon atoms. Harold Kroto, from the University of Sussex, James Heath, Sean O'Brien, Robert Curl and Richard Smalley, from Rice University, discovered C60 and the fullerenes. Kroto, Curl, and Smalley were awarded the 1996 Nobel Prize in Chemistry for their roles in the discovery of this class of compounds. C60 and other fullerenes were later noticed occurring outside of a laboratory environment (e.g. in normal candle soot). By 1991 it was relatively easy to produce grams of fullerene powder using the techniques of Donald Huffman and Wolfgang Krätschmer. As of the early twenty-first century, the chemical and physical properties of fullerenes are still under heavy study, in both pure and applied research labs. In April 2003, fullerenes were under study for potential medicinal use — binding specific antibiotics to the structure to target resistant bacteria and even target certain cancer cells such as melanoma. In October 2004, researchers at the University of Manchester and Institute of Microelectronics Technology and High Purity Materials at Chernogolovka discovered the first two-dimensional fullerene, called graphene.
Fullerenes are not very reactive due to the stability of the graphite-like bonds, and are also fairly insoluble in many solvents. Researchers have been able to increase the reactivity by attaching active groups to the surfaces of fullerenes.
Superconductivity is one of the more recently explored properties.
A common method used to produce fullerenes is to send a large current between two nearby graphite electrodes in an inert atmosphere. The resulting carbon plasma arc between the electrodes cools into sooty residue from which many fullerenes can be isolated.
