NEW FUNCTIONALIZED POLYTHIOPHENES

The development of a series of new functionalized polythiophenes prepared by electropolymerization is described. The corresponding monomers were synthesized starting with omega-haloalkyl substituted mono-, bi- and terthiophenes which were subsequently further reacted to yield viologens and ferrocenes. The characterization of both monomers and polymers revealed a dependence of the properties on the type of heterocyclic unit involved in the monomer, on the steric and electronic influence of the functional group and on the ratio of functional groups per monomeric units.
