The first MOF glass composed of metal-carboxylate cluster building units is vitrified by multi-stage transformations: The crystalline MOF is amorphized by vapor hydration and thermal dehydration, goes through a glass transition to enter a super-cooled liquid state, and recrystallizes into the initial structure. These multi-stage transformations are a rare example of high-temperature coordinative recognition and self-assembly.
