WebMar 4, 2011 · Fullerenes are characterized by the presence of 12 pentagons and varying number of hexagons in their structure. For fullerenes hexagons and pentagons are the main source of aromaticity and antiaromaticity, respectively. The study of the aromaticity of C 36 and C 60 revealed that C 60 has higher aromaticity than C 36 [ 12, 13 ].

In 2000, Andreas Hirsch and coworkers in Erlangen, Germany, formulated a rule to determine when a fullerene would be aromatic. They found that if there were 2(n+1) π-electrons, then the fullerene would display aromatic properties.
