Dynamic and reversible structural deformations in crystallographically oriented two-dimensional COF membranes upon solvent exposure are disclosed. We leverage this to design molecular separation membranes and correlate sieving pore sizes with the number of COF layers. The membrane delivers exceptional stability, molecular selectivity, and practicality for pharmaceutical purification.
