  • Conducting polymers derived from fluorinated thiophenes
    Patent number: 5268448
    Abstract: Substituted thiophenes of general formula: ##STR1## in which: R represents hydrogen atom or an aliphatic group containing from 1 to 4 carbon atoms,X and Z may be identical or different and represent a hydrogen atom or a fluorine atom,Y represents an at least partially fluorinated aliphatic or aromatic group,m represents an integer equal to or greater than 1, andn represents an integer such that 0.ltoreq.n.ltoreq.12.The invention also relates to the electrically conducting polymers containing recurring units derived from monomers chosen from the substituted thiophenes.
    Type: Grant
    Filed: June 16, 1992
    Date of Patent: December 7, 1993
    Assignee: Solvay S.A.
    Inventors: Werner Buechner, Marc Lemaire, Jean Roncali, Robert Garreau, Francis Garnier, Etienne Hannecart
  • Conductive polymers derived from aromatic heterocyclic compounds substituted by an ether-type group
    Patent number: 5204424
    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.
    Type: Grant
