High-spin radical cations of alternating poly(m-p-anilines)

Three alternating poly(m-p-anilines) are synthesized via palladium-catalyzed amination reactions and polymers are oxidized to radical cations by the use of chemical and electrochemical methods. The presence of radical cations is demonstrated by the appearance of two bands in UV-vis spectra, the positions of which depend on chemical structure of polymers.
