Pillar[5]arene-based ionic single crystals formed by dual self-assemblies through host-guest and ionic interactions for iodine capture

This study reports the first preparation of an ionically crosslinked pillar[5]arene single-crystal material (DMIBP5-NA) featuring a unique dual self-assembly structure. The material demonstrates excellent adsorption performance toward iodine vapor with an equilibrium adsorption capacity reaching 3.28 g g-1.
