We have
subjected single-walled carbon nanotube materials (SWNTMs) to a variety of
organic functionalization reactions. These reactions include radioactive
photolabeling studies using diradical and nitrene sources, and treatment
with dichlorocarbene and Birch reduction conditions. All of the
reactions provide evidence for chemical attachment to the SWNTMs, but
because of the impure nature of the starting materials we are unable to
ascertain the site of reaction. In the case of dichlorocarbene we are
able to show the presence of chlorine in the SWNT bundles, but as a
result of the large amount of amorphous carbon that is attached to the
tube walls, we cannot distinguish between attachment of dichlorocarbene to
the walls of the SWNTs and reaction with the amorphous carbon.
