Abstract

Earlier studies of conducting polymers focused on polyacetylene, (CH)x, where extended conjugation lengths and crystallinity are present. We present here the results of a detailed study of temperature dependent magnetic susceptibility and ac and dc transport of [CHDy] and [CHDy+zAz-]x where A is oxygen and iodine and 0.02≤y≤0.17. The CHDy introduce sp3 defects along the otherwise sp2 bonded polyacetylene chains and result in "segmentation" of the chain. Our results show that the presence of the sp3 bonded carbons has only a moderate effect on the conjugation of the pi band of polyacetylene.
