Gas exclusion zones in Type II porous liquids.

ABSTRACT: Porous liquids combine permanent porosity with fluidity and may ultimately find uses which are not possible for conventional liquids or porous solids. An important general characteristic of porous liquids studied to date is that they exhibit very high gas solubilities. Here, we examine this aspect in more detail than has been done previously, in particular with regard to CO₂ and CH₄ solubility in the Type II porous liquid Noria_OEt@15C5 (15C5 = 15-crown-5). Whilst this porous liquid exhibits increased CH₄ solubility compared to neat 15-crown-5, counterintuitively it actually exhibits equal or lower CO₂ solubility than the neat solvent 15C5 at pressures above 1 bar. Molecular dynamics modelling reveals that although the pore space does p
