Covalent Bond Formation to a Carbon Nanotube Metal

The pseudo–one-dimensional (psuedo-1D) conjugated electronic structure of single-walled carbon nanotubes (SWNTs) allows them to exhibit semiconducting and metallic properties and to exhibit ballistic transport (1). We show that their unique electronic structure also offers the opportunity for new horizons in chemistry by exploring the response of the Fermi level (EF) electronic structure of the metallic SWNTs to carbon-carbon bond formation at the nanotube surface.
