AbstractInclusion of the α,α′-bis(3-(1-methylimidazolium))-p- xylene dication in cucurbit[7]uril (CB[7], K = (4.3 × 10 M), with C-H⋯O=C hydrogen bonding between the guest C(2)-protons and the carbonyl oxygens of the host portals, inhibits the H/D exchange for the C(2)-proton with k (25°C, DO) decreasing from 1.2 × 10 M s (pK = 22.3) in the absence of CB[7] to 0.9 M s (pK = 25.4) in the presence of 1.1 equiv. CB[7]. © The Royal Society of Chemistry 2006.
