Microwave‐assisted fabrication of highly crystalline, robust COF membrane for organic solvent nanofiltrationIF:19.00

Fabrication of LZU1 Membrane: 100 mg of TFB was dissolved in 50 mL
of acetonitrile and sonicated for 10 min to obtain solution A. Then, 100 mg
of Pa and 6.25 mL of 3 m acetic acid aqueous solution were dissolved in
50 mL of acetonitrile and sonicated for 10 min to obtain solution B. The
aldehyde-modified Al2O3 substrate was placed face down in a homemade
holder, and solution A was added, solution B was slowly added dropwise
to solution A under stirring conditions. After the completion of dropwise
addition, polymerization was allowed to proceed in situ for 30 min. Subsequently, the mixture was transferred to a microwave synthesis instrument
and reacted at 100 °C for 60 min. After the reaction, the membrane was
removed and repeatedly soaked in ethanol, acetone, and DMF to remove
residual monomers and oligomers. Finally, the membrane was dried in a
vacuum oven at 60 °C to obtain the LZU1 membrane.
