Abstract
Metal-organic frameworks (MOFs) have gained interest in the field of heterogeneous catalysis owing to their high surface areas and tunability. A well-studied palladium bis(phosphinite) pincer complex was functionalized with carboxylic acid groups and used as a linker for MOF assembly. The metallolinker, H4[Pd-POCOP] (H4[Pd-POCOP] = IPd[C6H3-2,6-(Ar2PO)2], Ar = p-C6H4COOH), was used to assemble two analogous MOFs containing zinc and copper paddlewheel secondary building units. All materials were characterized using single crystal and powder X-ray diffraction methods. The zinc-based MOF was shown to react with select small molecules, resulting in ligand exchange at the zinc and palladium sites, and showing potential as a heterogeneous catalyst.
