Brominated single walled carbon nanotubes as versatile precursors for covalent sidewall functionalization.

Herein we report on the facile preparation of brominated SWCNTs based on two complementary reductive activation routes. The respective brominated SWCNTs are highly reactive and can be used in nucleophilic substitution reactions and represent versatile starting materials for the generation of sidewall functionalized SWCNTs with a high density of functional moieties.
