Fullerene chemistry is a field of organic chemistry devoted to the chemical properties of fullerenes. [ 1 ] [ 2 ] [ 3 ] Research in this field is driven by the need to functionalize fullerenes and tune their properties.
C 70 fullerene is the fullerene molecule consisting of 70 carbon atoms. It is a cage-like fused-ring structure which resembles a rugby ball, made of 25 hexagons and 12 pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge.
The closed fullerenes, especially C 60, are also informally called buckyballs for their resemblance to the standard ball of association football ("soccer"). Nested closed fullerenes have been named bucky onions. Cylindrical fullerenes are also called carbon nanotubes or buckytubes. [1] The bulk solid form of pure or mixed fullerenes is called ...
Fullerenes are typically spheroidal carbon compounds, the most prevalent being buckminsterfullerene, C 60. [2] One year after it was prepared in milligram quantities in 1990, [3] C 60 was shown to function as a ligand in the complex [Ph 3 P] 2 Pt(η 2-C 60). [4] Since this report, a variety of transition metals and binding modes were demonstrated.
Alternatively, endohedral hydrogen fullerenes can be produced by opening and closing a fullerene by organic chemistry methods. A recent example of endohedral fullerenes includes single molecules of water encapsulated in C 60. [10] Noble gas endofullerenes are predicted to exhibit unusual polarizability.
These endohedral fullerenes are usually synthesized by doping in the metal atoms in an arc reactor or by laser evaporation. These methods gives low yields of endohedral fullerenes, and a better method involves the opening of the cage, packing in the atoms or molecules, and closing the opening using certain organic reactions. This method ...
In chemistry, a metallofullerene is a molecule composed of a metal atom trapped inside a fullerene cage. Simple metallofullerenes consist of a fullerene cage, typically C 80, with one or two metal atoms trapped inside. Recently, research has produced metallofullerenes that enclose small clusters of atoms, such as Sc 3 N@C 80, Y 3 N@C 80, and Sc ...
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 ...
