Isolation and identification of fullerene family: C76, C78, C82, C84, C90 and C96

A preparative high-performance liquid chromatography was examined for the isolation of higher fullerenes from CS 2 extracts of the carbon soot produced by arc heating of graphite in inert atmosphere. At least eight all-carbon compounds C 60 , C 70 , C 76 , C 78 , C 82 , C 84 , C 90 and C 96 were confirmed as a “stable fullerene”. C 82 and C 96 are new members of fullerene family which have not been reported so far. The presence of stable C 82 seems to be closely related with the recent su macroscopic quantities of production of LaC 82 reported by Smalley's group.
