Transformation of a copper-based metal-organic polyhedron into a mixed linker MOF for CO capture.

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 [Cu(2,2'-bpy)(-BDC)] is comprised of a binuclear Cu(II) node coordinated to 2,2'-bipy, and isophthalic acid (-BDC), which bridges to neighboring nodes. The crystal structure of CuMOF-Bipy consists of a stacked two-dimensional framework with the topology.

Fluorine extraction from organofluorine molecules to make fluorinated clusters in yttrium MOFs.

A new rare earth based two-dimensional coordination network and a three-dimensional metal-organic framework (MOF) have been synthesized using bicinchoninic acid (BCA) and yttrium(iii) ions. Yttrium dimer nodes are formed in the absence of a modulator, resulting in a 2D layered coordination network (Y-BCA-2D). The presence of fluorinating agents, , 2-fluorobenzoic acid (2-FBA), 2,6-difluorobenzoic acid (2,6-DFBA), and perfluorohexanoic acid (PFHxA) result in μ-F bridged metal hexaclusters (YF) that form a three-dimensional MOF (Y-BCA-3D).
