Abstract
Abstract Perfluoropolycycloalkane are provided. These perfluoropolycycloalkanes are ring assemblies having (a) at least two perfluorinated cyclohexane rings, (b) at least two perfluorinated fused ring systems, or (c) combinations of at least one perfluorinated cyclohexane ring with at least one perfluorinated fused ring system, each perfluorinated ring or fused ring system being directly joined to another perfluorinated ring or ring system by a single bond and the ring assemblies having a total of at least 13 carbon atoms.
