Fullerene C₆₀ and C₇₀ which are the third allotropes of carbon, subsequent to diamond and graphite, have a beautiful spherical structure as shown in the figure. The form of Fullerene C₆₀ resembles the dome built by the architect, Buckminster Fuller, and therefore, it is called“ Buckminsterfullerene”.
The existence of Buckminsterfullerenes was hypothesized by Osawa¹⁾ more than 40 years ago and discovered by Smalley and co-workers²⁾ relatively recently. Afterwards, Huffman, Kratschmer and co-workers³⁾ have reported on the method to generate Fullerenes in a considerably large quantity. Fullerenes have been studied intensively, particularly in the fields of superconducting devices⁴⁾, ferromagnets⁵⁾, nonlinear optical materials⁶⁾, pharmaceuticals⁷⁾ and the like. Moreover, new Fullerene derivatives obtained by chemical modification⁸⁾ are being made and the chemistry of the new C₆₀ and C₆₀ derivatives are being explored in many different fields.
