Electron Localization in Polyaniline and its Derivatives

Abstract

Electron localization in HCl salt form of polyaniline (PAN-ES) and its methyl ring-substituted derivative, poly(o-toluidine)(POT-ES0, has been investigated by optical, transport and magnetic studies. Compared with PAN-ES, POT-ES has increased electron localization though the band structure, crystallinity and intrachain coherence length are similar for two polymers. The localization is proposed to be induced by a CH3 group on each C6 ring which decreases the interchain diffusion rate through reduction of interchain coherence and increased interchain separation.
