Abstract: Phenylcapped trianiline and tetraaniline in the leucoemeraldine oxidation state were synthesized through a modified-pseudo-high-dilution technique. The chemical oxidation process of these compounds were studied by UV-Vi s spectra. It was found that phenyl-capped trianiline in the leucoemeraldine oxidation state was oxidized to its EBform and then decomposed. Phenyl-capped tetraaniline was oxidized to its EBform and then to the pernigraniline oxidation state.
