“…[9] One attractive feature of FFs that distinguishes them from most other FCMs is that they are molecular and in many cases have been isolated with 85 mol % purity or higher as single isomers with well-determined structures and well-determined, reproducible physicochemical properties. [10] These FFs include 13 C 60 F n compounds (n = 2, 4, 6, 8 (two isomers), 18,20,24,36 (three isomers), 38, 48) and several dozen fluorinated higher fullerenes and heterofullerenes. [10] For any FF to become a practical component of an FCM for a particular application, its efficient synthesis and purification must be possible.…”
