Electrochemistry of Conducting Polymers—Persistent Models and New Concepts†

Side chains in conjugated polymers have been primarily utilized as solubilizing groups. However, these side chains have roles that are far beyond. We advocate using side chain engineering to tune a polymer’s physical properties, including absorption, emission, energy level, molecular packing, and charge transport. To date, numerous flexible substituents suitable for constructing side chains have been reported. In this Perspective article, we advocate that the side chain engineering approach can advance better designs for next-generation conjugated polymers.

Side Chain Engineering in Solution-Processable Conjugated Polymers

It has only been within the last few months that organic-solvent-soluble conducting polymers have been developed. Previously, solubility in a mixture of arsenic trifluoride/pentafluoride was the singular path available to processability of conducting polymers. In this paper they report their success in the preparation of two polymers which are soluble in water in the doped and undoped statesexclamation Sodium poly(3-thiophene-..beta..-ethanesulfonate) (P3-ETSNa) and sodium poly(3-(thiophene-delta-butanesulfonate) (P3-BTSNa) and their respective conjugate acids are water soluble. The latter are of interest because, upon oxidation, they can lose a proton concomitant with electron loss to produce self-doped polymers; i.e., doped polymers where the counterion is attached to the polymer via a covalent bond.
