Fig. 6. (a) Scheme demonstrating a potential gas loading/release cycle using sonication as a trigger; (b) overlaid liquid cell-FTIR spectra for the porous liquid over three CO₂ loading/release cycles (1^st cycle blue, 2^nd red, 3^rd green; solid lines = saturation; dashed lines = post sonication); (c) measured volumes of CO₂ evolved using sonication as the release mechanism for both the PL over five successive cycles and PCP; (d) relative quantity of CO₂ within the porous liquid over three loading/sonication cycles calculated from the FTIR spectra, with insets showing the FTIR CO₂ stretch in the porous liquid pre- and post-sonication.
