The synthesis of a new family of spheroidal carbon moleculesderived from the fullerenes is described. The fulleroids areproduced by incremental addition of a divalent carbon equivalentthat has two phenyl (Ph) rings to fullerene C₆₀. The fulleroidsPh₂C₆₁, Ph₄C₆₂, Ph₆C₆₃, Ph₈C₆₄, Ph₁₀C₆₅, and Ph₁₂C₆₆ have beenprepared and characterized.
