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), 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 optionally-substituted 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 form 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 CF3SO3 ions, which is relatively air- and water-stable and has a conductivity of about 1.0S cm<-1>. |
