Substituted thiophenes of general formula: ##STR1## in which: R represents hydrogen atom or an aliphatic group containing from 1 to 4 carbon atoms,

Conducting polymers derived from fluorinated thiophenes

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.

Conductive polymers derived from aromatic heterocyclic compounds

Substituted thiophenes of the general formula: ##STR1## in which: R represents a hydrogen atom, a halogen atom or an aliphatic group containing from 1 to 4 carbon atoms,

Substituted thiophenes, conducting polymers derived from these

The subject of the invention is mainly an electrically conductive polymer containing repeated units derived from 3-alkythiophenes in which the alkyl substituent contains from six to nine carbon atoms. The invention also relates to a process for manufacturing these polymers and to electroconductive devices containing them.
