Tweaking the properties of carbon nanotubes is a prerequisite for their practical applications. Here, we demonstrate fine tuning the electronic properties of single-wall carbon nanotubes via filling with ferrocene molecules. The evolution of the bonding and charge transfer within the tube is demonstrated via chemical reaction of the ferrocene filler ending up as secondary inner tube. The charge transfer nature is interpreted well within density functional theory. This work gives a direct observation of a fine-tuned continuous amphoteric doping of single-wall carbon nanotubes.
