Abstract

We report a synthetic method for shifting the pKa for the deprotonaton of polyaniline by the formation of non-covalent complexes between polyaniline and a polyanion. Depending on the choice of the polyanion and the condition of the synthesis, we can control the pKa value for the dedoping reaction to spread the pH range from 5.5 to 9.0. From a systematic study of the structural influence on the pKa values, we have verified that the electrostatic stabilization of the polaron is the origin for this unusually large pKa shift.
