The endohedral discandium fullerenes, Sc[sub 2]C[sub 74], Sc[sub 2]C[sub 82], and Sc[sub 2]C[sub 84], have been isolated for the first time from soot prepared by the arc burning of Sc[sub 2]O[sub 3]/graphite composite rods. The separation and isolation of the metallofullerenes from various hollow fullerenes have been realized by using a two-stage high-performance liquid chromatography. Laser-desorption time-of-flight mass analyses of the present samples confirm the isolation of the discandium fullerenes. The discandium fullerene, Sc[sub 2]C[sub 74], has been newly found in this study. The UV-vis absorption spectra of the isolated Sc[sub 2]C[sub 74], Sc[sub 2]C[sub 82], and Sc[sub 2]C[sub 84] reveal several salient features which are totally absent in those of the corresponding hollow fullerenes such as C[sub 76], C[sub 78], C[sub 82], and C[sub 84]. 17 refs., 4 figs.
