a Schematic illustration of LiOH-Am7CD-TMC membranes fabrication via interfacial polymerization. b Cryo-TEM micrographs of a 1.23%wt Am7CD•7HCl/0.03 M LiOH solution. Inset: high magnification image of assemblies. c Molecular packing of the Am7CD single crystal45 (top and side view). d Two-dimensional X-ray diffraction pattern of Am7CD membranes (LiOH-Am7CD-0.01 TMC). e AFM topographic image of the Am7CD membrane (LiOH-Am7CD-0.01 TMC) with dispersed crystals transferred onto a silicon wafer. f TEM images of Am7CD membranes with incorporated assemblies (LiOH-Am7CD-0.05 TMC), highlighting a high magnification detail. Inset (with a scale-bar of 1.5 nm): the magnification of a selected area showing distinct lattice fringes. g GIWAXS integrated one-dimensional pattern of Am7CD membranes (LiOH-Am7CD-0.01 TMC).
