Metal–organic framework crystal–glass composites (MOF CGCs) are a class of materials comprising a crystalline framework embedded within a MOF glass matrix. Herein, we investigate the thermal expansion behavior of three MOF CGCs, incorporating two flexible (MIL-53(Al) and MIL-118) and one rigid (UL-MOF-1) MOF within a ZIF-62 glass matrix. Specifically, variable-temperature powder X-ray diffraction data and thermomechanical analysis show the suppression of thermal expansivity in each of these three crystalline MOFs when suspended within a ZIF-62 glass matrix. In particular, for the two flexible frameworks, the average volumetric thermal expansion (β) was found to be near-zero in the crystal–glass composite. These results provide a route to engineering thermal expansivity in stimuli-responsive MOF glass composites. Metal−organic framework crystal−glass composites (MOF CGCs) are a novel class of composite materials that comprise crystalline MOFs within MOF glass matrices. In this work, we take a first glimpse at the expansion behavior of three separate crystalline MOFs within their respective MOF CGCs. It is observed that the surrounding glass matrix suppresses the expansion of each material leading to near-zero thermal expansion in two systems over a considerable temperature region.
