Figure 1 Fluorocarbons have been increasingly applied as media for chemical reactions and separations because their solubilizing properties are distinct from those of both water and traditional organic solvents. Sato et al. (p. 1273; see the Perspective by Gladysz) have created a nanometer-scale fluorous environment within a polar organic solvent. Arrow-shaped ligands with perfluoroalkyl tails self-assemble with palladium ions in dimethyl sulfoxide to form a shell in which the fluorinated chains are directed inward toward the center. By varying the lengths of these chains, the shell size could be tuned to encapsulate a liquid-like, disordered phase of ~2 to ~6 perfluorooctane molecules, which were characterized spectroscopically and crystallographically.
