Abstract

Abstract : Covalent organic frameworks (COFs) with high porosity and well‐organized channel structure are attractive candidates for advanced water treatment membranes. In their Communication onpage 4083 ff., H. Meng, J. Caro et al. present a two‐dimensional imine‐linked COF‐LZU1 membrane with a thickness of only 400 nm supported on alumina tubes that was synthesized by an in situ solvothermal method. The membrane exhibits excellent water permeance and high rejection combined with outstanding water stability for water‐soluble dyes with a size larger than 1.2 nm.
