Abstract

Soluble polyacetylenes with high conjugation length and high molecular weight are a goal of polymer scientists. The ring-opening metathesis polymerization of substituted cyclooctatetraenes (COT) to form soluble substituted polyacetylenes which display iodine doped conductivities in the range 0.1 to 50 S/cm are reported. The solubility is imparted by the alkyl groups which occupy, on average, every eighth carbon atom of the polymer backbone.
