Highly flexible and robust self-standing covalent organic framework (COF) membranes with rapid preparation are important but technically challenging for achieving precise separation. Herein , a novel imine-based 2D soft (SCOF) membrane large area of 226.9 cm2 via ingeniously selecting an aldehyde linker trigonal building block, is reported. The rapidly formed (≈5 min) based on the sodium dodecyl sulfate (SDS) molecular channel constructed at water/dichloromethane (DCM) interface, which...
