Interfacial polymerization is the industrial standard for desalination membranes. Extending this to nonaqueous environments, such as organic solvent nanofiltration (OSN), is vital for decarbonizing chemical industries. However, conventional polyamide thin-film composite (TFC) membranes often underperform in organic solvents due to their hydrophilic nature and poor resistance to swelling and plasticization. To address this issue, we report a molecular engineering approach using "acid-catalyzed interfacial polymerization" to develop advanced TFC membranes. Our strategy involves (1) switching the chemical linkage from amide to imine and (2) incorporating shape-persistent, micropore-generating units. The resulting membranes show exceptional performance in liquid hydrocarbon fractionation and ion separation for redox flow batteries.
