Conducting polymer solutions: An EPR and INDO/CI study of a radical cation observed in conducting poly( p-phenylene sulfide) solutions

Abstract
We report here the observation of resolved EPR hyperfine couplings for the conducting polymer AsF5‐doped poly( p‐phenylene sulfide), dissolved in liquid AsF3. Correlation of the EPR and INDO results indicates that the observed signal is due to a nonplanar sulfur‐centered radical cation with the hyperfine pattern arising from the coupling of the electron to the four meta 1H’s on the adjacent phenyl rings.
