Abstract
The interaction of organometallic chromium‐centered free radicals generated by the homolytic dissociation of (pentamethylcyclopentadienyl)chromiumtricarbonyl dimer in toluene with single‐walled carbon nanotubes (SWNT) was investigated using ESR spectroscopy. Low values of g‐factors of the radical species formed from chromium‐centered free radicals and SWNT as well as invariability of disorder mode (D band) intensity in Raman spectra of pristine and functionalized SWNT after this reaction indicated that chromium‐centered free radicals added to the surface of nanotubes through rather oxygen atoms than to sidewall carbon atoms. This is the first chromium‐derivatization of carbon nanotubes.
