Functionalization of Single-Walled Carbon Nanotubes

“…[14,33] For example, the thermal reaction of azidoformiates leads to N 2 extrusion and to aziridinoSWNTs (Scheme 2), which dissolve in organic solvents such as DMSO to give black solutions. [33] Especially stable solutions of functionalized SWNTs are formed from the addition of nucleophilic carbenes. [33] In this case, no cyclopropanation occurs, rather, each added group is…”

“…Sidewall functionalization of SWNTs with alkyl azidoformiates. [33] bound through just one covalent bond to the tube and is positively charged. One negative charge per added group is transferred to the nanotube framework, as in the analogous reactions with C 60 .…”

“…Atomic-force micropscopy shows that the original bundles of SWNTs are broken up in the course of adduct formation. [33] In a similar fashion, SWNTs were functionalized by reaction with azomethinylides. [34] The degree of functionalization of the resulting pyrrolidines is very high, which causes a high solubility in organic solvents.…”

The Role of Functional Moieties on Carbon Nanotube Surfaces in Solar Energy Conversion

“…[12,[21][22][23][24][25] We reported in our earlier study that maximum amidization of MWCNTs could be achieved through the acid chloride route, for which the yield is not more than 5 %.
