Abstract

This thesis is concerned with the following ligands to use to coordinate and react to copper: a pyrimidine: niacinamide, the polyazine monocyclic triazine: cyanuric acid, and bicyclic N- donating hydrocarbons: quinoxaline and caffeine. When reacted with cuprous salts consisting of organic ligands they form multi-ligand coordination supramolecular architectures (1) or halides to form copper halide clusters. In the novel compounds, metal-metal interactions occur, which exhibit low-lying triplet state charge transfers, allowing the tunability of a photon-emitting compound which is expected to form the emission. Cuprous metal centers also possess the ability to self-assemble to form coordination polymers. Group 11 d10 coinage metals exhibit strong metal-to-ligand charge transfers (MLCT) as well.(50) Characterization of all compounds was completed using thermogravimetric analysis, X-ray crystallography, Fourier transform infrared spectroscopy (FTIR), and photoluminescence spectroscopy. The acquired data is analyzed and discussed further in the following thesis.
