Abstract :
The electrochemical, optical and magnetic properties in polyarylene-vinylene conducting polymers, such as poly-p-phenylene vinylene (PPV), poly-1,4-naphthalene vinylene (PNV), and poly-2,5-thienylene vinylene (PTV), during electrochemical p- and n-type doping have been investigated by cyclic voltammetry, optical absorption spectroscopy, and ESR measurements. These results are discussed in terms of polaron and/or bipolaron models and lead to a better understanding of the electronic levels. The evolution of localized states upon doping is dependent on molecular structure and successful n-type doping in PTV and PNV is suggested. Furthermore, new optical recording techniques utilizing the precursor films of PPV and its derivatives have also been prepared
