The characterization of polyazulenes is reported with regard to two main aspects. First, results of circular dichroism spectroelectrochemistry of a carbohydrate‐modified azulene indicate that structural reorganization and chiroptical switching occur on oxidative doping. Second, the investigation of phenylene/azulene polymeric films with meta ‐ or para ‐phenylenes as bridging units provides information about electron transport and shows that phenylenic bridging allows structurally separated electron‐transfer‐active subunits to be created within the polymeric chain.
