An electrically conducting organic material for use on battery electrodes and the like, which comprises a polymer optionally doped with an n- or p- type dopant, wherein the polymer contains along its backbone at least one .pi.-conjugated linear unit of formula I I wherein A is a divalent optionally-substituted conjugated organic cyclic group containing a .pi.-conjugated sequence of single bonds and at least two double bonds, B is a tetravalent optionallysubstituted conjugated organic cyclic group containing a .pi.conjugated sequence of single bonds and at least one double bond; A and B have the same molecular and structural formula except that they contain a different configuration of double and single bonds; Y is a trivalent group containing m linking atoms between adjacent groups A and B where m is an odd number from 1 to 11, provided that when Y contains more than one linking atom between said adjacent groups, the linking atoms from a .pi.-conjugated chain of atoms between said adjacent groups A and B, and n is an integer from 1 to 4. One example of the material is poly(2,2'dipyrrylmethane) doped with CF3SO? ions, which is relatively air- and water-stable and has a conductivity of about 1.05 cm-1. |
