摘要

Coulombically repulsive cationic guests can be encapsulated in the multicomponent capsule hosts via favorable ion pairing, H-bonding intermolecular interactions. The inclusion of protonated and diprotonated 2-pycolyl amine guests in the calix[4]arene tetrasulfonate, tetrasodium salt C[4]) host is reminiscent with complex dynamic equilibria in solution. The addition of AG aminoguanidinium cations to such mixtures results in the formation of distinct crystalline bilayer and capsule architectures in the solid state. This show that libraries of interexchanging supramolecular components may convert into robust solid state multicomponent capsules via constitutional crystallization.
