We succeeded in establishing for the first time a conclusive spectroscopic signature for reducedsingle-wall carbon nanotubes (SWNT), which evolves from electron donor-acceptor interactions betweenSWNT and electron-donating -extended tetrathiafulvalene (exTTF). In particular, - interactions wereemployed to anchor the electron donor to the surface of SWNT. New conduction band electrons, injectedfrom photoexcited exTTF, shift the transitions that are associated with the van Hove singularities to lowerenergies.
