Searches for methods of volatile organic compound sensor devices by the examination of photoluminescence and photoluminescent materials such as metal complexes. Shows the synthesis and structural characterization of the bridging ligand, 1-methylbenzimidazole diphenylphosphine. Examines the coordination mode of this ligand to gold and silver metals. Observes the stucture of the mononuclear gold complex, a gold dimer, and a silver dimer in non-polymeric form with notable differences around the metal center. Describes the electronic properties of the ligand and metal complexes. Explores the sensitivity of the dimer gold complex to acetonitrile.
