a Adsorption isotherms of O2 (red) and Ar (black) at 140 K. Solid and hollow points represent the adsorption and desorption isotherms, respectively. b Qst of O2 (red) and Ar (black) for PFAC-2. c IAST selectivity (O2:Ar = 50:50) at 140 K for PFAC-2. d–f Breakthrough curves of O2 (red) and Ar (black) for an equimolar O2/Ar mixture at 140 K and 1 bar for PFAC-2, HAC-2, and blank samples, respectively. C and C0 represent outlet and inlet concentrations for each gas, respectively.
