The progress of electrically conducting polymers is reviwed. Synthesis and properties of mainchain conjugated polymers are described in the first section, among which are polyacetylene, polypyrrole given by anodic oxidation of pyrrole, poly (<I>p</I>-phenylene sulfide) and pyropolymers. They show high electrical conductivities through doping with electron acceptors or electron donors. The mechanism of doping and the nature of electrical carrier are discussed. The second section is devoted to the description of characteristics of amorphous conducting polymers given by the modification of side chains, and “molecularlydoped polymers” in which electrically active molecules are dispersed in an inert polymer matrix. A molecular localized state prevails and the hopping mechanism is accepted for electrical conduction in these materials. Finally, organic photoconductive polymers are dealt with from the standpoint of the preparation, photogeneration and carrier transport properties. Also is explained the design of carrier transport compounds based on the perturbation molecular orbital theory.
