Chemical in situ modulation of doping interactions between oligoanilines and nanocarbon films

The electronic properties of carbon nanotubes are commonly customized through doping with various moieties, however, the modification is permanent as long as the dopant is present. Here we present a family of dopants that can be switched on and off while in place via environmental stimuli, in particular redox conditions and exposure to acids and bases. Aniline oligomers are firmly attached to the carbon nanotubes and are not easily displaced by …
