A new anionic metal-organic framework for highly efficient removal of cationic pollutant in water

•A new anionic MOF ZJU-71 was synthesized and structurally characterized.•ZJU-71 has one-dimensional channels along a axis and a scu type topology.•ZJU-71 can quickly and effectively remove the trace amounts of methylene blue.

A novel 3D anionic microporous metal-organic framework, Cu2(H4DCPPA) (ZJU-71, H4DCPPA=[1,1′:2′,1′′-terphenyl]-4,4′,4′′,5′-tetracarboxylic acid, ZJU=Zhejiang University), has been synthesized and structurally characterized. ZJU-71 possesses one-dimensional channels along a axis and a scu type topology. The negative electricity of the framework makes ZJU-71 an candidate for effective elimination of cationic contaminants.
