High hydroxide conductivity in a chemically stable crystalline metal–organic framework containing a water-hydroxide supramolecular chain

Abstract

A chemically stable cationic MOF encapsulating an in situ formed water-hydroxide supramolecular anionic chain is realized for high hydroxide (OH⁻) ion conductivity in the solid-state (Type A). High OH⁻ ion conductivity and low activation energy of the MOF demonstrate the advantage of the in situ incorporation of OH⁻ ions to achieve efficient OH⁻ ion conduction in the solid-state.
