Like many other organic conducting polymers, polyacetylene is electrochemically active, attracting a great deal of interest both from the scientific and the applied point of view. In the year 2000 the chemistry Nobel Prize was granted to A. J. Heeger, H. Shirakawa, and A. G. MacDiarmid for their work on polyacetylene and the nature of conducting polymers. 

Organic conductors can naturally be subdivided into two types single crystals and polymers. The former have experienced a rapid development from semiconductors (1950 s - 1960 s) (1) to metals (1970 s) (2) to superconductors (1980 s) (3). Highly conducting organic polymers (except "pyropolymers" and composites) have had a shorter history. 

These are presented by two subclasses of electroactive polymer (i) -conjugated polymers of both organic and inorganic nature [5-15] and (ii) conventional redox polymers [26], and by inorganic ion-insertion (intercalation) compounds [27, 28[ (see the top of Scheme 11.1b). Despite the different nature of their chemical bonds, all of these compounds are mixed, electronic-ionic conductors [29], and hence, their electronic and/or ionic conductivity is expected to change with the applied potential in a predictable, characteristic manner (see Section cl 1.4).
