    Abstract

    The endohedral metallofullerenes, such as Sc@C82, Sc2@C84, and Sc3@C82, have been purified and isolated by using two-stage high-performance liquid chromatography (HPLC). The ESR spectrum of the isolated Sc3@C82 exhibits a perfectly symmetric 22 hyperfined splittings with an inherent linewidth of 0.77 Gauss at 220 K, which is consistent with a unique structure that three scandium atoms are encaged triangularly within the C3v isomer of C82. In addition, we report the direct imaging of the isolated discandium fullerene (Sc2@C84) on silicon clean surfaces in an ultrahigh-vacuum environment by utilizing scanning tunneling microscopy (STM). The STM images reveal spherical Sc2@C84 fullerenes, spaced 11.7 Å apart, stacked in close-packed arrays.
