A pillar[5]arene decaamine has been synthesized and revealed to encapsulate linear diacids in neutral, alkaline, acidic conditions, driven by the hydrophobic electrostatic interactions, give rise pseudo[2]rotaxanes. Ion pair-bonded stoppers can further lock generate stable water soluble [2]rotaxanes.
