Abstrakt: It is increasingly apparent that porous liquids (PLs) have unique use cases due to the combination of ready liquid handling and their inherently high adsorption capacity. Among the PL types, those with permanent porosity are the most promising. Although Type II and III PLs have economic synthetic methods and can be made from a huge variety of metal-organic frameworks (MOFs) and solvents, these nanocomposites still need to be stable to be useful. This work aims to systematically explore the possibilities of creating PLs using different MOF modification methods. This delivered underpinning insights into the molecular-level influence between solvent and MOF on the overall nanocomposite stability. Zirconium-based metal-organic frameworks were combined with two different solvents of varying chemistry to deliver CO 2 sorption capacities as high as 2.9 mmol g -1 at 10 bar. The results of the study could have far-reaching ramifications for future investigations in the PL field.
