Abstract

A series of triarylamine polymers were prepared by palladium-catalyzed polycondensation. Extension of the π-conjugation was analyzed by UV and electrochemical measurements, which revealed the degree of off-coplanarity in the polymer framework. Chemical oxidation of the polymer with NOPF6 gave the corresponding poly(aminium cationic radical). The ESR signal at room temperature indicated an exchange interaction between the radicals in the polymer. The spectrum recorded at 12 K displayed a ΔMs = ±2 transition signal at half-field, which was characteristic of multiplet species.
