A preparative high-performance liquid chromatography was examined for the isolation of higher fullerenes from CSz extracts of the carbon soot produced by arc heating of graphite in inert atmosphere. At least eight all-carbon compounds CW, CT,,, C,,, CT8, Cs2, Csl, Cgo and Cq6 were confirmed as a "st

✦ Synopsis
The electronic structures of mono-anionized higher fullerenes (C,, C,, C, and C, ) associated with the major experimental product have been investigated bused on their optimized structures employing the semi-empirical (MIND0/3) molecular orbital calculations. Not a very drastic structural change has been observed between the neutral and mono-anionized states except for change in symmetry of Ds,&s,. It has been found that the charge and the spin distributions in these anions are somewhat similar to C% but more dispersive and are quite different from those in C& ' To whom correspondence should be addressed.
