It has a cage-like fused-ring structure (truncated icosahedron) made of twenty hexagons and twelve pentagons, and resembles a soccer ball. Each of its 60 carbon atoms is bonded to its three neighbors. Buckminsterfullerene is a black solid that dissolves in hydrocarbon solvents to produce a violet solution. The substance was discovered in 1985 ...

Researchers have been able to increase the reactivity of fullerenes by attaching active groups to their surfaces. Buckminsterfullerene does not exhibit "superaromaticity": that is, the electrons in the hexagonal rings do not delocalize over the whole molecule. A spherical fullerene of n carbon atoms has n pi-bonding electrons, free to ...

Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.
Rendering of a buckminsterfullerene containing a noble gas atom (M@C 60). Electron microscopy images of M 3 N@C 80 peapods. Metal atoms (M = Ho or Sc) are seen as dark spots inside the fullerene molecules; they are doubly encapsulated in the C 80 molecules and in the nanotubes. [1]
Fullerene is a relatively new substance in chemistry sciences. Buckminsterfullerene itself was discovered in 1985 [1] and the first fullerene-containing polymers were reported at least 6 [2] years later. The main milestones in the use of fullerene in polymer chemistry are listed below: 1992 – Synthesis of organometallic C 60 polymer (C 60 Pd ...
