Fig. 3: Microenvironment modulation for regulating water flow and simulation.
From: Sub-8 nm networked cage nanofilm with tunable nanofluidic channels for adaptive sieving
a Schematic illustration showing the microenvironment modulation of the pore windows via anion exchange. b Separation performance enhancement after TFSI− exchange. c Time-dependent UV/Vis spectra of the iac-cage-azo membrane at 298 K, using UV and Vis (inset) irradiation. d, e Ratio of trans/cis state with UV and Vis light irradiation time, respectively. f Changes of the absorption band of iac-cage-azo membrane at 330 nm upon alternating irradiation by UV and visible light. g Simulation snapshot of water molecules transporting through the iac-cage-TFSI membrane. The enlarged snapshot shows the water chains inside the cage network. h Numbers of transferred water molecules Nw through cage membranes with various counterions.
