Modem semiconductor devices now have feature dimensions less than 0.1 Jl.m, but the capacitor in DRAM circuits of computers is not yet able to scale down to the necessary dimensions. Creating a smaller, more efficient capacitor (one able to store more information) is the next step in enhancing semiconductors. To achieve a more efficient capacitor on such a small scale, a compound needs to be synthesized that is highly redox active and able to form SAMs on a gold surface for use in computer DRAMs. The precursor ligands MeMPTP and MPTP were synthesized and characterized in order to synthesize a copper-ligand coordinated species, [Cu11MeMPTP]Ch, and the capped ligand [Cu11LtHBPA]. The redox activity of [Cu11MeMPTP]Ch and [Cu11LtHBPA] was established using cylclic voltometry and resulted in. a reversible redox process for Cu1 to Cu11 in both compounds, and nonreversible processes for their respective ligands. Knowing that these compounds possess the potential for redox activity, namely with copper at the metal center, allows for. future improvement of the compound on the basis of increased redox capability.
