Properties of Single-Component Metal-Organic Framework Crystal-Glass Composites.
The formation, and subsequent structural, thermal and adsorptive properties of single-component metal-organic framework crystal-glass composites (MOF-CGCs) are investigated. A series of novel materials exhibiting chemically identical glassy and crystalline phases within the same material were produced, where crystalline ZIF-62(Zn) was incorporated within an agZIF-62(Zn) matrix. X-ray diffraction showed that the crystalline phase was still present after heating to above the glass transition temperature of agZIF-62(Zn), and interfacial compatibility between the crystalline and glassy phases was investigated using a mixed-metal (ZIF-62(Co))0.5(agZIF-62(Zn))0.5 analogue. CO2 gas adsorption measurements showed that the CO2 uptakes of the MOF-CGCs were between those of the crystalline and glassy phases.
