Fig. 1

a 3D conformation and distribution of electrostatic potential at the molecular van der Waals surface of ODA monomer. b Diagram of interfacial polymerization between TMC and ODA at the alkane/DES interface. c Photograph of the free-standing PA formed at alkanes/DES interface. d AFM image and corresponding height profile of the free-standing ODA/TMC membrane. e SAXS Q-I plot in log-log scale of ODA/TMC and MPD/TMC in vacuum. f CO2 absorption isothermals of ODA/TMC and MPD/TMC. g Molecular dynamics simulation of free volume of ODA/TMC and MPD/TMC network. h Porosities of ODA/TMC measured by different sizes of probes.
