Mixtures of cyclofluoroalkylated fullerenes are provided by the thermal 2+2 cycloaddition of fluoroalkenes to a solution or slurry of a fullerene. The cyclofluoroalkylated fullerene mixtures are useful as lubricants or additives to lubricants; in fluorocarbon and/or chlorofluorocarbon based cooling systems; in adhesives for fluorocarbon based polymers and in gas separation membranes.
