Anionic Metal–Organic Framework for Selective Dye Removal and CO2 Fixation

A microporous Zn‐based anionic metal–organic framework (MOF) was synthesized with triangular 4,4′,4′′‐(pyridine‐2,4,6‐triyl)tribenzoic acid. The anionic MOF material featuring open channels proved to be a good capturing agent for the cationic dye methylene blue. In addition, the Zn‐MOF demonstrated excellent catalytic activity for CO 2 fixation by cycloaddition reaction with epoxides for the generation of cyclic carbonates.
