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 ...
The presence of fullerenes has resulted in shungite being of interest to researchers as a natural reservoir, though shungite is not uniquely enriched in fullerenes compared to other carbon-rich rocks. [14] Shungite has been used as a folk medical treatment since the early 18th century.
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.

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.

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.
