We have synthesized large ruthenium (Ru) complexes that can bind to carbon nanotubes to give them enhanced functionality. By manipulating ligands on Ru, we control the size and the charge state of Ru complexes. These molecules will allow us to study interactions of carbon nanotubes with each other in solution as well as with other molecular systems. These new molecules extend our current capabilities. We will present the synthesis of some, and modeling of other large, rigid and optically useful ruthenium dendrimers of various size, shape and charge. We believe that we can promote and control electron transfer between carbon nanotubes and the Ru complexes. Taking advantage of carbon nanotubes' good electron accepting properties and mechanical stiffness we will discuss how these supramolecular complexes are applicable to photovoltaic and solar cells.
