摘要：

Sulfonated dendrons with mono-SO3H group as protonic acid dopants were used to prepare polyaniline emeraldine base (PANI-EB). By a self-assembly process we obtain nanostructures (nanotubes and nanorods) of PANI with an average radius of 100-150 nm. It was found that the formation probability and size of PANI-EB nanostructures depended on the generation number of dendrons, the molar ratio of aniline to sulfonated dendrons and the concentration of sulfonated dendrons. Sulfonated dendrons or aniline-sulfonated dendrons salt micell as the self-assembled "template" for the formation of PANI nanostructures was further verified.
