Abstract:
A metal–organic framework (MOF) for reversible alteration of guest molecule adsorption, here carbon dioxide, upon photochemical or thermal treatment has been discovered. An azobenzene functional group, which can switch its conformation upon light irradiation or heat treatment, has been introduced to the organic linker of a MOF. The resulting MOF adsorbs different amount of CO₂ after UV or heat treatment. This remarkable stimuli-responsive adsorption effect has been demonstrated through experiments.
