Abstract

Supramolecular hydrogels have been constructed with flexible 2D ionic framework assemblies comprised of a stick-shaped di-cationic pseudo-rotaxane and polyanionic nanoclusters through electrostatic interactions. This type of small-molecule hydrogel exhibits excellent thermal stability at high temperature and shows an efficient reduction of water evaporation enthalpy.
