The purpose of this thesis is to investigate the effect on field effect transistors when using graphitic materials fabricated with "piano stool" or cyclic polyhapto compounds. Graphene's superior electrical and thermal conductivity has already been proven to result in lower resistance losses and enhance heat dissipation compared to silicon. Consequently, graphene-based transistors have the potential to provide enhanced performance and efficiency. Research has also shown that the electronic properties of graphene can be improved by fabrication with transition metal complexes having a vacant d-orbital. This paper builds on the work started by Dr. Haddon's group and aims to synthesize new materials of graphitic compounds with "piano stool" compounds. The extended periodic π-electron systems of graphene exhibited some degree of reactivity toward Cr(CO)6 and (η6- benzene)Cr(CO)3 and complexation with graphene by removing the labile CO ligand is indicated. To understand the trends in the chemistry and stability of the complexes based on molecular interactions and surface environments, ATR-IR, Raman Spectroscopy, and XPS were conducted. To evaluate the conductivity, a four-probe measurement of sheet resistance was performed. The cyclic polyhapto complexes of graphene are expected to have improved electronic properties relative to the starting graphitic materials which will be ideal in FET applications, but scalability remains an issue.
