A grapevine nanostructure based on single‐walled carbon nanotubes (SWNTs) covalently functionalized with [60]fullerene (C 60 ) has been synthesized and characterized in detail. Investigations into the ball‐on‐tube carbon nanostructure by ESR spectroscopy indicate a tendency for ground‐state electron transfer from the SWNT to the C 60 moieties. The cyclic‐voltammetric response of the nanostructure film exhibits reversible multiple‐step electrochemical reactions of the dispersed C 60 , which are strikingly similar to those of the C 60 derivatives in solution, but with consistent negative shifts in the redox potential. This results from the covalent linkage of C 60 to the surfaces of the SWNTs in the form of monomers and manifests the electronic interaction between the C 60 and SWNT moieties.
