  2. Fullerene - Wikipedia

    en.wikipedia.org/wiki/Fullerene

    Fullerenes had been predicted for some time, but only after their accidental synthesis in 1985 were they detected in nature [3] [4] and outer space. [5] [6] The discovery of fullerenes greatly expanded the number of known allotropes of carbon, which had previously been limited to graphite, diamond, and amorphous carbon such as soot and charcoal.

    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.

  4. Spherical aromaticity - Wikipedia

    en.wikipedia.org/wiki/Spherical_aromaticity

    In organic chemistry, spherical aromaticity is formally used to describe an unusually stable nature of some spherical compounds such as fullerenes and polyhedral boranes. In 2000, Andreas Hirsch and coworkers in Erlangen , Germany , formulated a rule to determine when a spherical compound would be aromatic .

    en.wikipedia.org/wiki/Azafullerene

    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.

  6. Buckminsterfullerene - Wikipedia

    en.wikipedia.org/wiki/Buckminsterfullerene

    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 ...

    Since then, superconductivity has been reported in fullerene doped with various other alkali metals. [ 4 ] [ 5 ] It has been shown that the superconducting transition temperature in alkaline-metal-doped fullerene increases with the unit-cell volume V. [ 6 ] [ 7 ] As Cs + is the largest alkali ion, caesium-doped fullerene is an important ...
