Factors affecting conduction in polymeric complex TCNQ salts

Abstract
Conductivity measurements are reported on both isotactic and atactic polyvinyl pyridinium complex TCNQ salts. The isotactic materials are significantly better conductors than those derived from atactic materials, but not as good as those derived from the monomeric base. Seebeck and microwave Hall mobility measurements indicate that the isotactic materials behave as polycrystalline complex radical salts, whereas the atactic materials exhibit behaviour consistent with hopping conduction.
