ABSTRACT

A highly conjugated organic polymer ( having unsaturated bonds spaced along the polymer chain intermittently ) such as polyacetylene has been known to exhibit high electronic conductivity when oxidized by suitable reagents . Likewise a number of conjugated hydrocarbon and aromatic heterocyclic polymers ( such as poly-p-phenylene،  poly-p- phenylene-vinylene  ،  poly-p-phenylene sulfide ، polypyrrole and polythiophene as well as radical salts like tetracyanoquinodimethane ( TCQN) complexes have also been identified as conducting Polymers organometallics.In terms of technological applications of these materials they have been deployed as rectifiers sensors solar energy conversion elements fuel cell components switching devices photoresist elements chemoselective electrodes electrophotographic devices and durable synthetic materials replacing metals. Speculative applications on possible high temperature superconductive applications of these materials also prevail .
