Host鈥揼uest complexation between a novel difunctional pillar[5]arene-based host H and alkyldiamines was fully investigated in both solution and the solid state. Proton transfer from the carboxylic acid groups to the amine units occurred in the principle by undergoing an acid鈥揵ase reaction. Driven by the cooperativity of electrostatic interactions, multiple C鈥揌路路路蟺 interactions, and H-bonds, the guests penetrated into the cavity of H to form pseudorotaxane-type inclusion complexes with relatively high binding affinities.
