Claim 13:
14. The method of claim 11, wherein said (co)polymers of a 3,4-dialkoxythiophene are selected from the group consisting of
(co)polymers comprising repeating units having general formula (I):, in which R1 and R2, identical or different, represent a hydrogen atom or are selected from C1-C4 alkyl groups; or R1 and R2 together represent a C1-C5 alkylene group or a cycloalkylene group;
(co)polymers of a 3,4-dialkoxythiophene in which the two alkoxy groups together represent an optionally substituted oxy-alkylene-oxy bridge;
(co)polymers of a 3,4-dialkoxythiophene in which the two alkoxy groups together represent an oxy-alkylene-oxy bridge optionally substituted with one or more groups selected from the group consisting of alkyl groups, alkoxy groups, alkyloxyalkyl groups, carboxyl groups, alkylsulphonate groups, arylsulphonate groups, and ester groups; and
(co)polymers of a 3,4-dialkoxythiophene in which the two alkoxy groups together represent an oxy-alkylene-oxy bridge in which the alkylene group is selected from the group consisting of an optionally substituted 1,2-ethylene group; a methylene group optionally substituted with at least one alkyl group; a 1,2-ethylene group optionally substituted with at least one C1-C12 alkyl group; a 1,2-ethylene group optionally substituted with at least one phenyl group; a 1,3-propylene group; and a 1,2-cyclohexylene group.
