Synthesis and characterization of supramolecular nanostructures of carbon nanotubes and ruthenium-complex luminophores

We constructed and characterized supramolecular nanostructures consisting of ruthenium-complex luminophores, which were directly grafted onto short oxidized single-walled carbon nanotubes or physically entrapped in silica nanobeads, which had been covalently linked to short oxidized single-walled carbon nanotubes or hydrophobically adsorbed onto full-length multi-walled carbon nanotubes. These structures were evaluated as potential electron-acceptor complexes for use in the fabrication of photovoltaic devices, and for their properties as fluorescent nanocomposites for use in biosensors; or nanoelectronics.
