A NEW P-DOPANT FOR POLYACETYLENE

We report here a new type of p-doping for polyacetylene. The new dopan t is the (CF3SO2N- ion, We reached a conductivity of 20 S/cm for a mol ar doping level of the order of 8%. We performed Raman measurements an d observed the characteristic peaks of cis- and trans-polyacetylene si multaneously. We observed also photoluminescence. This behaviour is in terpreted as the result of an inhomogenous doping. We present also the dependence of the EPR linewidth as a function of the chemical doping time.
