The gas uptake in the new PLs based on 2-ethylphenol and 2-methyl-1-phenyl-2-propanol gave higher CH4 solubiliVes (36 µmol mL -1 and 33 µmol mL -1 ) than those discovered in the previous high-throughput experimental study at the same concentraVon (2-hydroxyacetophenone, 26 µmol mL -1 ), though not meeVng the uptakes recorded in the original scrambled PL based on the perchlorinated solvent discovered in 2017 (81 µmol mL -1 ). The CH4 uptake in the porous liquids based on 1-phenylethanol and 2-phenyl-1propanol (both 14 µmol mL -1 ) were lower than 2-ethylphenol and 2-methyl-1-phenyl-2-propanol. The lower uptake for 1-phenylethanol reflects the predicVon that this solvent is only potenVally size-excluded based on the KDE, while the highest performing solvents were predicted to be excluded with more confidence. The downfield shib of the CH4 NMR signals (Table ) reflect the gas uptake enhancement, the values range from -0.97 ppm to -2.28 ppm in line with previously reported data, further indicaVng the CH4 molecules are occupying the cage pore as the electron rich arene walls shield the 1 H nuclei from the external magneVc field.
