  • Metal-doped fullerenes and synthetic methods therefor
    Patent number: 5348936
    Abstract: Superconducting, metal-doped fullerenes are provided, along with processes for their preparation in relatively high stoichiometric purity. In one embodiment, the processes provide fullerenes of the formula M.sub.x C.sub.q, where M is a metal, x is greater than 0 but less than about 10, and q is at least 60. The processes comprise contacting C.sub.q with metal in an amount and under reaction conditions effective to produce a compound having the formula M.sub.y C.sub.q, and contacting said M.sub.y C.sub.q with a portion of C.sub.q in an amount and under reaction conditions effective to produce said M.sub.x C.sub.q, wherein y is greater than x.

  • Process for preparing alkali metal-doped fullerenes
    Patent number: 5223479
    Abstract: Superconducting, metal-doped fullerenes are provided, along with processes for their preparation in relatively high stoichiometric purity. In one embodiment, the processes provide fullerenes of the formula M.sub.3 C.sub.60 where M is an alkali metal. The processes comprise contacting C.sub.60 with alkali metal in an amount and under reaction conditions effective to produce a compound having the formula M.sub.y C.sub.60, where y is greater than 3, and contacting said M.sub.y C.sub.60 with a portion of C.sub.60 in an amount and under reaction conditions effective to produce said M.sub.3 C.sub.60.
