Abstract
Liquids with permanent porosity can be created by incorporating empty cavities into liquid phases hence adding novel functionalities to conventional fluid absorbents and opening new perspectives for a range of applications including separations, catalysis and drug delivery. The preparation of porous liquids is difficult, especially in the case where they consist of a neat fluid composed by molecular entities containing empty cavities (type I porous liquid) or when these molecular entities are dissolved in sterically hindered solvents (type II porous liquids). Amongst the synthetic approaches proposed so far, the dispersion and stabilisation of solid porous materials in hindered solvents, too large to enter the pores of the solid allowing the formation of type III porous liquids, has not been considered. We have prepared a new porous liquid from the dispersion of well characterized metal-organic frameworks in an appropriately chosen ionic liquid. Both ionic liquids and metal-organic frameworks are new families of materials, now easily prepared and available as off-the-shelf chemicals whose fascinating properties have already lead to applications in engineering, physics, chemistry and medicine. Porous liquids prepared by the addition of only 2 to 5% of ZIF-8 to a phosphonium base...
