Conjugated polymers are of general interest due to their desirable optical and electrical properties. Polythiophenes are one of the most versatile of the various conjugated polymers studied, due to their environmental stability and the ease with which they can be synthetically modified. Although a large variety of functionalized polythiophenes have been studied, polythiophenes containing N-alkyl- or N-aryl-amino moieties have not been reported due to the lack of synthetic routes to the required monomeric precursors. The preparation of a variety of N-functionalized and N,N-difunctionalized 3-aminothiophenes will be presented along with polymerization studies utilizing various chemical methods. Characterization of the resulting polymeric materials will also be presented.
