Nitroxide radicals are one of the most stable and reversible-redox radical. Here, we report on a hole-transporting radical polymer. We synthesized a poly(phenylenevinylne) derivative 1 which contains triarylamine moiety substituted with a nitroxide radical. Cyclic voltammetry of the polyradical 1 revealed the reversible redox at 0.46 (V vs Ag/AgCl). This first redox of the polyredical 1 was due to the unpaired electron of the radical moiety. We fabricated a organic light-emitting device involving a hole-injecting layer with the polyredical 1 (ITO/1/TPD/Alq3/LiF/A1) which showed electroluminescence derived from Alq3.
