Electroactive carbon nanoforms: a comparative study via sequential arylation and click chemistry reactions

The reactivity of several carbon nanoforms (CNFs), single-walled carbon nanotubes (SWCNTs), multi-walled carbon nanotubes (MWCNTs) and graphene, has been investigated through a combination of arylation and click chemistry CuI-mediated azide–alkyne cycloaddition (CuAAC) reactions. The approach is bas...
