A 2-fold interpenetrating 3D pillar-layered MOF for the gas separation and detection of metal ions

Abstract

A 2-fold interpenetrating 3D pillar-layered MOF, which was assembled from a mixed-linker and paddle-wheel cluster, was successfully synthesized. It possesses good thermal and water stability as well as high selectivity for C₂H₆ over CH₄ and CO₂ over N₂ under ambient conditions, which was further proved by breakthrough experiments. Moreover, this porous material exhibits good detection of Cu²⁺, [Co(NH₃)₆]³⁺ and Fe³⁺ in an aqueous solution.
