A zirconium-based metal–organic framework with dibenzothiophene linkers: synthesis, structural analysis, and gas-adsorption properties

Abstract

A UiO-67-type Zr-based metal–organic framework (MOF) with dibenzothiophene linkers, UiO-67-S, was synthesized using a solvothermal method. The crystal structure of UiO-67-S exhibits the same topological structure as UiO-67 and its derivatives. UiO-67-S shows high thermal stability and excellent permanent porosity. Moreover, its excellent hydrogen storage indicates that the thiophene moiety is suitable for enhancing the hydrogen storage ability of MOFs.
