Graphene is a single sheet of the material graphite and comprises a two-dimensional array of hexagonally organized sp2-hybridized carbon atoms. Graphene is an electrical conductor, and exploration is in progress to synthetically modify the structure of graphene to change it into a semiconductor. Semiconducting graphene could potentially be used to manufacture solid-state electronics that are currently constructed from silicon. Theoretical investigations demonstrate that subtle changes to the graphene structure utilizing η6-bound M(CO)3 or (arene)M fragments (M = Cr, W) may convert graphene into a semiconductor. This project will investigate a solution phase route to this transformation using graphene oxide, which is soluble. The approach involves refluxing a mixture of graphene oxide and M(CO)6 or (arene)M(CO)3 in a high boiling solvent mixture to bind the M(CO)3 or (arene)M fragments to the graphene oxide surface. Preparation and characterization of the products resulting from reaction between the metal containing precursors and graphene oxide will be characterized by using Raman spectroscopy, (X-ray photoelectron spectroscopy (XPS), Transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR). The data collected gave values close to those of Haddon and support compound formation in some cases. This project will enable future researchers to synthesize and more fully characterize the products. An important technique that will be used is Kelvin probe force microscopy (KPFM) to measure and determine possible changes in conductivity of the metal-containing products.
