http://www.xarxbio.com/news/news-63615.html In organic chemistry, spherical aromaticity is formally used to describe an unusually stable nature of some spherical compounds such as fullerenes, polyhedral boranes. 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. This follows from the fact that an aromatic fullerene must ha…
