Abstract : Proton abstraction doping has been demonstrated as a viable alternate procedure for the synthesis of electrically conductive polymers through the preparation of poly(phenylene pentadienylene). Additional procedures being used for the synthesis of proton abstraction doping precursors includes sulfur ylide and Grignard condensations, details will be presented. These systems offer tremendous advantages for the study of effects arising from dopant density and conjugation length in organic conductors. One interesting result involves the conductivity of 1,5-diphenypentadiene, a low molecular weight model for poly(p-pheynlene pentadienylene). 1,5-Diphenylpentadienyl anion displays a conductivity of 8S/cm which supports the conclusion that polymeric delocalization of charge is not a necessity.
