Bisimidazolium salts with one central biphenyl binding site and two terminal adamantyl binding sites form water‐soluble binary or ternary aggregates with cucurbit[7]uril (CB7) and β‐cyclodextrin (β‐CD) with rotaxane and pseudorotaxane architectures. The observed arrangements result from cooperation of the supramolecular stopper binding strength and steric barriers against free slippage of the CB7 and β‐CD host molecules over the bisimidazolium guest axle.
