Analogies Between Graphite Intercalation Compounds and Doped Polyacetylenes

Graphite intercalation compounds are compared with doped polyacetylenes. It is shown that a number of analogies exist between both classes of materials, concerning for example the dopant species or the doping mechanism. Finally, a structure study of polyacetylene doped with iodine and sodium shows that doping may be considered as an intercalation reaction.
