| 抄録: | A dilution effect on the proton conduction of a hydronium solvate ionic liquid [H₃O⁺centerdot18C6]Tf₂N, which consists of hydronium ion (H₃O⁺), 18-crown-6-ether ligand (18C6), and bis[(trifluoromethyl)sulfonyl]amide anion (Tf₂N⁻; Tf = CF₃SO₂), has been studied. When [H₃O⁺･18C6]Tf₂N was diluted using equimolar 18C6 solvent, the distinctive fast proton conduction in [H₃O⁺･18C6]Tf₂N was suppressed in stark contrast to the case of common protic ionic liquids. Nuclear magnetic resonance spectroscopy showed that the fast exchange between free 18C6 molecules and coordinated ones, suggesting that the added solvent had induced a local proton exchange rather than a cooperative proton relay. |
