Bucatica de CHIMIE – Buckminsterfullerene

File:Buckminsterfullerene-perspective-3D-balls.png

Buckminsterfullerene (or buckyball) is a spherical fullerene molecule with the formula C60. It has a cage-like fused-ring structure (Truncated icosahedron) which resembles a soccer ball, made of twenty hexagons and twelve pentagons, with a carbon atom at each vertex of each polygon and a bond along each polygon edge.

It was first intentionally prepared in 1985 by Harold KrotoJames R. Heath, Sean O’Brien, Robert Curl and Richard Smalley at Rice University.[2]Kroto, Curl and Smalley were awarded the 1996 Nobel Prize in Chemistry for their roles in the discovery of buckminsterfullerene and the related class of molecules, the fullerenes. The name is a homage to Buckminster Fuller, as C60 resembles his trademark geodesic domes. Buckminsterfullerene is the most commonly naturally occurring fullerene molecule, as it can be found in small quantities in soot.[3][4] Solid and gaseous forms of the molecule have been detected in deep space.[5]

Buckminsterfullerene is the one of the largest objects to have been shown to exhibit wave–particle duality.[6] Its discovery led to the exploration of a new field of chemistry, involving the study of fullerenes.
