Luminescent copper(I) complexes, in particular Cu(I) halide clusters, have attracted significant attention in the literature of coordination chemistry. Particular attention has been paid to monodentate arylamine ligands such as pyridine and its derivatives regarding the production of luminescent cluster complexes. Our group has been exploring reactions of such Cu(I) halide coordination complexes focusing on the effects of altering different synthetic conditions with various bidentate imine  ligands on the structure and photophysical properties of the resultant cluster and coordination polymer products. The new copper complexes display vivid colors and luminescence properties at room and cryogenic temperatures.  This presentation wills emphasize how various ligands, synthetic routes and reaction conditions (e.g., presence vs absence and/or identity of solvent, temperature, stoichiometry, etc.) affect the product structure and material properties. Various ligands examined include 3-cyanopyridine and different pyrazoles. Photoluminescence, UV/Vis electronic absorption, nuclear magnetic resonance (NMR), and infrared (IR) spectral results will be presented for the various reactions and reaction conditions.
