Abstract
Electrically conductive polymers containing repeat units derived from five-membered aromatic heterocyclic monomers substituted, in the 3 position relative to the heteroatom, by an ether-type substituent linked to the heterocyclic ring by an alkylene radical containing at least two carbon atoms. The invention also relates to certain monomers enabling the above-mentioned conductive polymers to be obtained.
