Transformation of a copper-based metal–organic polyhedron into a mixed linker MOF for CO2 capture

Abstract

A new mixed linker metal–organic framework (MOF) has been synthesized from a copper-based metal–organic polyhedron (MOP-1) and 2,2′-bipyridine (2,2′-bipy). The CuMOF-Bipy with a formula of [Cu2(2,2′-bpy)2(m-BDC)2]n is comprised of a binuclear Cu(II) node coordinated to 2,2′-bipy, and isophthalic acid (m-BDC), which bridges to neighboring nodes. The crystal structure of CuMOF-Bipy consists of a stacked two-dimensional framework with the sql topology. CuMOF-Bipy was characterized by single-crystal X-ray diffraction (SC-XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and CO2 sorption. CuMOF-Bipy was shown to have one-dimensional sinusoidal channels that allow diffusion of CO2 but not N2.
