Fullerene C60 and its application
As everyone knows, there are two kinds of carbon allotropes:diamond and graphite. In 1970, Japanese scientists Ozawa predicted that the nature of carbon should also exist in third allotropic forms. After the world scientists 15 years of unremitting efforts and arduous exploration, in 1985, American University of Rice Kroto et al. finally find clusters containing 60 carbon atoms in the experiment of laser vaporization of graphite for the first time, named C60. Atomic clusters containing 70 carbon atoms are named as C70. C60 and C70 have a cage like structure, in the physical and chemical properties can be regarded as three-dimensional aromatic compounds, molecular three-dimensional configuration is D5h point group symmetry.

20 hexagon and 12 pentagons of C60 constitute a spherical structure. The structure consists of 60 vertices, respectively occupy by 60 carbon atoms, confirmed third allotropes of carbon they belong to, called fullerenes.

Fullerene can be used in the manufacture of superconductors, organic soft magnet, optical materials, functional polymer materials and biological materials et al. As a kind of important material product, it has a variety of uses in many fields and more and more uses will be developed in the future.
