摘要：

The curvature and topology required for fullerene formation strongly enhances the electronegativity of the carbon clusters and as a result C60 readily accepts electrons. Solid C60 undergoes doping with alkali metal vapors to produce intercalation compounds which are conductors.During the doping process the predominant phases present are: C60, A3C60 and A6C60. The A3C60 compounds are formed from C60 by occupancy of the interstitial sites of the fcc lattice.These phases constitute the first three-dimensional organic conductors and for A = K, Rb, the A3C60 compounds are superconductors.
