Synthesis of Parent Aniline Hexamer via One-step Method and Its UV-Vis Spectral Study

Abstract

Abstract: The parent aniline hexamer was synthesized in the emeraldine base(EB) oxidation state through one step oxidative coupling reaction using parent aniline trimer in the leucoemeraldine oxidation state. The hexamer in the EB state was reduced by phenylhydrazine in ethanol and was characterized by IR, ¹H NMR , MALDI-TOF-MS and elemental analysis. The chemical oxidation process of the hexamer was studied by UV-Vis spectra. It was found that the hexamer was oxidized to its EB form and then to the pernigraniline oxidation state.

Key words: Oxidative coupling reaction, Polyaniline, Parent aniline hexamer
