Non-covalent ruthenium polypyridyl complexes-carbon nanotubes composites: an alternative for functional dissolution of carbon nanotubes in solution

摘要

The dispersion of single-walled carbon nanotubes (SWCNTs) in the presence of water soluble polypyridyl complexes of the general formula [Ru_x(bpy)_yL]~(2 +) (L = dppz, dppn, tpphz) is reported. These ligands have extended planar n systems, which aid in the solubilization of SWCNTs via π-π interactions.
