Abstract

In this work we present results of in situ optical absorption, electron spin resonance, as well as Fourier transform infrared spectroscopic studies during electrochemical doping and undoping processes of viologen functionalized poly(3-alkylthiophenes). Two reduction processes of the viologen side group in addition to the oxidation process of the polythiophene backbone are observed. The spectroscopic data indicate influences of the viologen side group on the electronic properties of polythiophene backbone. Radicals on the viologen side group show hyperfine structured electron spin resonance signals indicating a rapid motional averaging of anisotropic electron-nuclear couplings.
