The synthesis of a new family of spheroidal carbon molecules derived from the fullerenes is described. The fulleroids are produced by incremental addition of a divalent carbon equivalent that has two phenyl (Ph) rings to fullerene C60. The fulleroids Ph2C61, Ph4C62, Ph6C63, Ph8C64, Ph10C65, and Ph12C66 have been prepared and characterized.
