Lipid metal organic networks
Abstract
Metal-organic frameworks (MOFs) first appeared in the literature in 1991[1] and consist of three dimensional structures constructed by linking transition metal ions together through highly directional bonding with organic ligands [2]. MOF materials offer the ability to choose from variety of metal centers that allow the tailoring of optical or magnetic properties, as well as control, to some extent, the size of the coordination sphere [3]. Another advantage is the numerous organic ligands form which suitable pore geometries may be constructed with customized functionality [2] among many applications in other areas such a gas storage [4], chemical separations [5] and selective catalysis [6]. The primary objective of this research was to develop the methodology for the preparation of a new class of MOFs that we call lipid metal organic networks (LMON), which use fatty acid derivatives of biomass in combination with bridging dipyridyl ligands such as 4-4’-Trymethylene dipyridine [7] and transition metal ions to form extended moldable crystalline polymers. The single-crystal X-ray structure of a model LMON is reported in order to provide evidence of the possible molecular structure of LMONs. This thesis presents seven unprecedented LMONs of high molecular weight that exhibit thermoplastic properties at relatively low temperatures.
