Polyconjugated polymers like poly(acetylene) undergo redox reactions resulting in metal‐like conductivity. Due to the complex morphology of the polymer the structure, state of order and the mechanism of carrier generation and transport are not well understood. Two different model systems which are available as well defined single crystals are presented. In polydiacetylene crystals the mobility of charge carriers along isolated and over macroscopic distances defect‐free polymer chains can be studied. The radical cation salts of simple arenes serve as models for the structure and charge transfer interactions in the metallic conductive phases of polymers.
