TOWARD METAL-ORGANIC FRAMEWORKS CONTAINING NONBENZENOID ISOCYANOARENES AND HALF-SANDWICH IRIDIUM (III)-BASED BUILDING BLOCKS
Metal-organic frameworks (MOFs) are compounds composed of metal ions connected to organic ligands (or bridges) to provide a 2D or 3D porous structure. Unfortunately, 2D molecular squares and rectangles are not well studied. A 2D square or rectangle combines metal-based fragments, which serve as the corner pieces, with organic bridges, the edge piece, to create a planar macrocylic structure. The focus of this study is to obtain a better understanding of 2D MOFs as a precursor to 3D MOFs. More specifically, this project examined the ability of the half-sandwich cyclopentadienyl-iridium(III) fragment to act as a corner piece and support multiple bulky 2-isocyano-1,3-diethoxycarbonylazulene (isocyanoazulene) ligands. To accomplish this, three nonbridging isocyanoazulenes were attempted to be successively added to a half-sandwich iridium(III)-based metal fragment. These complexes will serve as models of the corner piece of a 2D and 3D MOF when bridging ligands are used.
