Covalent organic frameworks (COFs) with high porosity and well‐organized channel structure are attractive candidates for advanced water treatment membranes. In their Communication (DOI: 10.1002/anie.201712816) 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 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.

管状氧化铝载体上的高通量亚胺键合共价有机框架COF-LZU1膜可通过纳滤实现高选择性染料分离

具有高孔隙率和井井有条的通道结构的共价有机骨架（COF）是高级水处理膜的有吸引力的候选者。在他们的交流中（DOI：10.1002 / anie.201712816）H.Meng，J.Caro等。提出了一种二维亚胺连接的COF-LZU1膜，其厚度仅400 nm支撑在通过原位溶剂热法合成的氧化铝管上。对于尺寸大于1.2 nm的水溶性染料，该膜表现出优异的透水性和高截留率，并具有出色的水稳定性。
