A pcu-type metal–organic framework based on covalently quadruple cross-linked supramolecular building blocks (SBBs): structure and adsorption properties

Abstract

A flexible ligand with two 1,3-benzenedicarboxylate units has been used to construct a microporous metal–organic framework with pcu topology based on supramolecular building blocks (SBBs). The obtained Cu(II) MOF exhibits a noticeable CO2 adsorption hysteresis and a comparable methane adsorption capacity at room temperature.
