Abstract

Blue poly(phenylene ethynylene) (PPE) electroluminescence (EL, see Figure) is obsd. in a hybrid org. light-emitting diode (OLED) with Commission Internationale de l'Eclairage coordinates of (x = 0.17; y = 0.20). Energy transfer from a hole-transport host to polystyrene-grafted PPEs is utilized to improve the poor LED characteristics of traditional PPE-based systems. [on SciFinder(R)]
