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 sorption capacities as high as 2.9 mmol g at 10 bar. The results of the study could have far-reaching ramifications for future investigations in the PL field.
越来越明显的是，由于易于进行液体处理及其固有的高吸附能力相结合，多孔液体（PLs）具有独特的应用案例。在PL类型中，具有永久孔隙率的那些是最有前途的。尽管II型和III型PLs具有经济的合成方法，并且可以由各种各样的金属有机框架（MOF）和溶剂制成，但这些纳米复合材料仍需要稳定才能有用。这项工作旨在系统地探索使用不同MOF改性方法制备PLs的可能性。这为溶剂和MOF之间在分子水平上对整体纳米复合材料稳定性的影响提供了基础见解。将锆基金属有机框架与两种化学性质不同的溶剂相结合，在10巴下实现了高达2.9 mmol g的CO吸附容量。该研究结果可能对PL领域未来的研究产生深远影响。
