The article reviews recent progresses in functionalization of single-walled carbon nanotubes (SWCNT). Detailed studies of electronic, chemical, and structural properties of intercalated and filled carbon nanotubes using state-of-the-art spectroscopic and microscopic techniques are described. Intercalation with alkali metal allows one to fine tuned the electron-doping level of SWCNT. A photoemission study of potassium intercalation compounds of SWCNT bundles unveils a transition of the metallic ground state of a SWCNT bundle from Tomonaga–Luttinger liquid state to Fermi liquid state. In turn, the filling of single-walled carbon nanotubes with fullerenes and organic molecules facilitates a reality of nanochemistry using carbon nanotubes as a nanoreactor. A combined spectroscopic and microscopic investigation of the interconversion of encapsulated fullerenes and organic molecules unveils either a catalytic or a noncatalytic process for the inner-tube growth from different filler precursors. Such encapsulated reactions vary the chemical status of filling material which eventually leads to a modulation of the doping level of the carbon nanotube host.
