On Polaron and Bipolaron Formation in Conducting Polymers

Abstract

Spin concentration has been measured as a function of charge injection in polypyrrole, polyaniline, and polydithiophene. Analysis of the data in terms of polarons and bipolarons in thermodynamical equilibrium leads to polarons and bipolarons nearly degenerate for polypyrrole and polyaniline. In the case of polydithiophene the data support the bipolarons as the fundamental charged species. However, the spin susceptibility does not decrease at low temperature as expected for fundamental spinless species. We propose that the polaron pairing is hindered by potential barriers and, consequently, polarons and bipolarons are not in thermodynamical equilibrium.
