Fluorous solvents, which are both hydrophobic and lipophobic, could be ideal bulk membranes for both (in)organic ions and molecules. Fluorous resorcinarenes (FR-n) are synthetic hosts for cations (e.g., tetramethylammonium ion) and their complexes could only be dissolved in the fluorous phase. Deprotonation of FR-n at the interface with a basic source phase and protonation of its complex at the interface with an acidic receiving phase offer a driving force for transport.
