SOLUTION PROPERTIES OF SINGLE-WALLED CARBON NANOTUBES

Naked metallic and semiconducting single-walled carbon nanotubes (SWNT s) were dissolved in organic solutions by derivatization with thionych loride and octadecylamine. Both ionic (charge transfer) and covalent s olution-phase chemistry with concomitant modulation of the SWNT band s tructure were demonstrated. Solution-phase near-infrared spectroscopy was used to study the effects of chemical modifications on the band ga ps of the SWNTs. Reaction of soluble SWNTs with dichlorocarbene led to functionalization of the nanotube walls.
