The semi-conducting properties of carbon nanotubes have been the focus of recent research in efforts to produce novel nanoscale photovoltaic cells. Attaching photoreceptive chromophores to these tubes provides an electron donor-acceptor complex from which a photovoltaic cell can be designed. The synthesis of donor-acceptor complexes incorporating various substituted and/or metallated porphyrins will be pursued. The complexes will be characterized using various spectroscopic techniques, including UV-VIS absorption spectroscopy, fluorescence spectroscopy and laser flash photolysis.
