ABSTRACT:
An at least semiconductive polymer film is provided by infiltrating novel rigid-rod heterocyclic polymer film containing a 2,2'-bipyridine-5,5'-diyl moiety, with a conductive metal salt. These polymers have repeating units of the formula ##STR1## wherein Z is selected from the group consisting of ##STR2## wherein Q is --H or --C.sub.6 H.sub.5. Alternatively, the metal salt in the semiconductive polymer film can be reduced.
