Spectroelectrochemistry of carbon nanostructures

This review is focused on charge-transfer reactions at carbon nanotubes and fullerenes. The spectroelectrochemistry of fullerenes deals with a spin states of fullerenes, the role of monoanions and the reactivity of higher charged strates in C-60. The optical (Vis - NIR) spectroelectrochemistry of single-walled carbon nanotubes (SWNTs) follows changes in the allowed optical transitions among the Van Hove singularities . The Raman spectroelectrochemistry of SWNT benefits from strong resonance enhancement of the Raman scattering. Here, both semiconducting and metallic SWNTs are analyzed using the radial breathing mode (RBM) and G-modes as well as the second order (D,G') and intermediate frequency modes Raman spectroelectrochemistry of SWNT allows the addressing of index-identified tubes and oven single isolated nanotubes. Optical and Raman spectroelectrochemistry of fullerene peapods, C-60@SWNT indicates effective shielding of the intratubular fullerene (peas). The most striking effect in the spectoelectrochemistry SWNT allows the addressing of index-identified tubes and even single isolated nanotubes. Optical and Raman spectroelectrochemistry of fullerene peapods, C-60@SWNT and C-70@SWNT indicates effective shielding of the spectroelectrochemistry of peapods is the so called anodic Raman enhancement of intratabular C-60. Double-walled carbon nanotubes (DWNTs) give a specific spectroscopic response in Vis = NIR spectroelectrochemistry for the inner and the outer tube. They are better distinguishable by Raman spectroelectrochemistry which allows a precise tracing of the specific doping response of outer/inner tubes.
