Abstract
Polymers which have two or more stable, reversibly interconvertible oxidation states with half-wave potentials E.sub.1/2 of from -1.5 to +1 V, and which are obtained when a polymer having a reactive side group is reacted with a 1,9-substituted phenalene, are useful for producing electrically conductive systems, in the electrical industry, and for converting and fixing radiation, for producing electric switches, as electrochromic displays, for providing an antistatic finish on plastics and as reversible redox systems.
