Back Cover: High‐Flux Membranes Based on the Covalent Organic Framework COF‐LZU1 for Selective Dye Separation by Nanofiltration (Angew. Chem. Int. Ed. 15/2018)

Abstract

Covalent organic frameworks (COFs) with high porosity and well-organized channel structure are attractive candidates for advanced water treatment membranes. In their Communication on page?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.
