Film obtained by the electrolytic polymerization of pyrrole monomer and pyrrole under addition of dipyrrin-l(10H)-ones, which can act as polymer chain end groups, are compared. The effect of the doping anion and of ageing on electrical conductivity are studied. Elemental chemical analysis of the film materials points to the presence of short polymer chains: comparison with similar polymerizations of 3,4-dimethyl pyrrole suggests the presence of/~,/Y' cross-linking in the polypyrrole structure
