that the Rh metal coordinates to these nanotubes through the increased number of oxygen
atoms, forming a hexacoordinate structure around the Rh atom. The reaction process
increases oxidized nanotube solubility in DMSO (> 150 mg/L) as well as to a certain extent
in DMF and THF. The functionalization process results in exfoliation of larger bundles of
SWNTs and may select for the presence of distributions of smaller-diameter tubes. Optical …
