Abstract

The dynamic structure of liquid water can be disrupted by the presence of non‐polar organic molecules, in a process known as hydrophobic solvation. Maria Giménez‐López, Francisco Rivadulla et al. demonstrate in their Communication on page 7540 that the particular orientation of hydrocarbon chains in tetraalkylammonium and phosphonium salts induces a peculiar structure of water molecules different from the bulk, changing its physicochemical properties.
