Inside Cover: Surface Wetting in Liquid–Liquid–Solid Triphase Systems: Solid‐Phase‐Independent Transition at the Liquid–Liquid Interface by Lewis Acid–Base Interactions (Angew. Chem. Int. Ed. 33/2012)

Lewis acid–base interactions at the oil–water interface can greatly decrease the liquid–liquid interfacial tension and induce an oleophilic-to-superoleophobic wetting transition on a nonresponsive microstructured surface. In their Communication on page 8348 ff., L. Jiang and co-workers report a strategy for tunable surface wettability that is independent of the solid phase. Oil-water-solid triphase systems may find new applications in chemical reactions.
