| Abstract: | Electrochemical doping of nanocarbons is an elegant alternative to chemical doping with redox active molecules. Single-wall carbon nanotubes (SWCNT), fullerene peapods (C60@SWCNT, C70@SWCNT) and double-wall carbon nanotubes (DWCNT) have been studied in detail during the last 5 years. The favorable features of electrochemistry consist in precise control of the doping charge and large variability in the selection of counterions compensating electronic charge at the carbon nanostructure. The optical and Raman spectra of nanocarbons acquired in situ reflect complex feedback to electrochemical tuning of the population of electronic states near the Fermi level. This allows the addressing of fundamental questions about the electronic structure and physical properties of carbon nanotubes and related species. Besides aqueous and aprotic electrolyte solutions, ionic liquids are readily applicable for Vis-NIR and Raman spectroelectrochemistry of nanocarbons in a broad interval of electrochemical potentials. This paper reviews the salient data, acquired on optical and Raman spectroelectrochemistry of SWCNT, fullerene (C60, C70) peapods and DWCNT. | |
