The porous liquids investigated (using the three different batches of MOF with uptakes of 277, 457 and 766 µmol/g), both under ambient conditions and under UV irradiation, demonstrated at least 82% of the theoretical calculated total uptakes. The MOF also retained its bulk crystallinity after being dispersed in the ionic liquid and after gas uptake measurements under both ambient conditions and under UV irradiation (Figure , S12, S15). In addition, on sonicating the MOF in [BMIM][NTf2] a visibly stable dispersion was formed, which showed good stability with no obvious creaming or sedimentation occurring on standing over several months (Figure ).
