摘要：

Understanding the chemistry of chemical doping, Which is necessary to generate charge carriers in pi-conjugated polymers, have become increasingly important for increasing charge carrier mobility, a primary requisite for the development of polymer electronic devices. An evidence for disruption in pi-conjugation upon increase in doping is evidenced by changes in characteristics bands in Fourier transform infra-red (FT-IR) spectroscopy, influence of structural damage oil morphological changes in atomic force microscopy(AFM) and monitoring the conductivity patterns versus doping concentrations. Quest for finding the reason behind such all unwanted chemistry is uncovered by solution proton nuclear magnetic resonance (H-1 NMR) spectroscopy of various combinations of dopant and to be doped species. Knowing the reason of disruption of pi-conjugation will prove useful in developing careful doping chemistries, utterly important for polymer electronic devices. (C) 2007 Elsevier Ltd.
