| 抄録: | We observed a new class of proton conduction in a hydronium (H₃O⁺) solvate ionic liquid (IL). The IL is described as [H₃O⁺·18C6]Tf₂N⁻; Tf = CF₃SO₂) anion. Self-diffusion coefficient measurements revealed that protons of H₃O⁺ (solute ion) move faster than 18C6 ligand (solvent), marking the first observation of ligand exchange conduction not only among solvate ILs but also among protic ILs without free neutral molecules. The presence of ligand exchange conduction without inducing external electric field indicates that solvation of H₃O⁺ by 18C6 is kinetically labile, i.e. ligand exchange is very fast for the reaction H₂O + 18C6 + HTf₂N ⇌ H₃O⁺·18C6]Tf₂N, while the equilibrium shifts to the right. The fundamental findings regarding the hydronium solvate IL will help in the design of proton conductors. |
