Abstract A method for covalent functionalization of multiwalled carbon nanotubes (MWCNTs) was developed using the free radicals generated through Bergman cyclization of enediyne- containing compounds. Four enediyne-bearing Frechet type dendrimers were synthesized in good quantities and characterized. Then, the enediyne-containing molecules were reacted with MWCNTs in N-methyl-2-pyrrolidinone at 206 C under nitrogen. The structure ...
