Copper (I)Halides complexes with various diamine ligands have recently generated a lot of focus due to their unique photophysical properties and ability to arrange in diverse structures. Multiple copper (I) Iodide - phenanthroline complexes have been synthesized by a solvent-mediated reaction and a solventless reaction via mechanical grinding. The reaction of the same starting materials resulted in multiple products with different interesting photophysical properties upon varying: a)the synthetic method of the reaction, solvents, or a greener solvent-less route b) molar ratios of the starting material. The novel products have been characterized using different methods and instrumentation such as: Fourier-transform infrared (FTIR), Thermogravimetric Analysis (TGA), Ultraviolet–visible spectroscopy (UV-Vis), Nuclear Magnetic Resonance (NMR), luminescence spectroscopy (steady-state and lifetimes), Elemental Analysis, along with crystallization and X-ray diffraction. Potential applications consist of solar energy materials, energy-efficient light- emitting diodes (LED), smart phones, organic LED (OLED) TVs, medical drugs, and diagnostic tools for cancer and other diseases.
