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.
