摘要：

Covalent organic framework (COF) membranes are attractive candidates for molecular separation. Herein, COF-LZU1 composite membranes were prepared by a stoichiometric spraying layer-by-layer self-assembly method for the first time. The membranes displayed a high rejection (>90%) and permeance (>400 L m(-2) h(-1) MPa-1, 50-880% higher than traditional membranes) for dyes (M-w 350-800).
