Modular Type III Porous Liquids Based on Porous Organic Cage Microparticles

The dispersion of particulate porous solids in size-excluded liquids has emerged as a method to create Type III liquids, mostly using insoluble microporous materials such metal–organic frameworks and zeolites. Here, the first examples based on organic cages (POCs) are presented. By exploiting solution processability POCs, racemic quasiracemic cage microparticles formed by chiral recognition. Dispersion these range including oils ionic forms stable POC-based liquids. flexible pairing between solid POC particles carrier liquid allows formation compositions, pore sizes, other physicochemical properties suit different applications operating conditions. For example, it is shown that with relatively low viscosities or high thermal stability can be produced. A 12.5 wt% comprising an liquid, [BPy][NTf2], shows CO2 working capacity (104.30 µmol gL?1) significantly higher than neat (37.27 25 100 °C. This colloidally recycled at least ten times without loss capacity.
