Charge Transfer at Carbon Nanotubes with Encapsulated C60 and C70 (Peapods).
Original language description
Charge-transfer on fullerene peapods (C60@SWCNT and C70@SWCNT) was studied by electrochemistry in 0.2 M LiClO4 + acetonitrile and in 1-butyl-3-methylimidazolium tetrafluoroborate (ionic liquid). This method allows easy and precise control of the population of electronic states near the Fermi level. Electrochemistry of peapods is dominated by capacitive double-layer charging, analogous to that of empty tubes. No fullerene-related faradaic processes are detectable in peapods. Vis-NIR spectroelectrochemistry points to reversible and fast bleaching of the electronic transitions between Van Hove singularities, which also causes reversible quenching of resonance Raman scattering of both radial breathing and tangential modes of SWCNT. Anodic charging of C60@SWCNT leads to intensity enhancement of the C60 Raman modes. This 'anodic enhancement' is not reproduced in C70@SWCNT. All the relevant modes of C70-peapods show the normal symmetric charge-transfer bleaching as the tube-related lines.
