Metal-organic frameworks (MOFs) consist of metal ions and organic molecules that are assembled into rigid 3-dimensional networks.  The resulting network structures offer a wide range of potential application including gas storage, chemical sensing, drug delivery, solid-state catalysis, and selective chemical filtering. The vast number of possible ligand-metal combinations gives rise to great variability in MOF synthesis.  We have successfully prepared and characterized two novel organic ligands that may be used to synthesize new MOF materials: di-3-pyridyl-formamidine (3-HDpyF) and di-pyrazyl-formamidine (HDpyzF).  These molecules feature diametrically opposed metal binding regions.  The formamidinate binding region is known to support dimetal centers, while the nitrogen donors of the pyridyl and pyrazyl groups are expected to coordinate with additional metal ions thereby forming a 3-dimensional network. We are currently investigating the coordination chemistry of these novel ditopic ligands.  The synthesis and characterization for 3-HDpyF, HDpyzF, and their associated metal complexes will be presented.
