摘要：

Blue poly(phenylene ethynylene) (PPE) electroluminescence (EL, see Figure) is observed in a hybrid organic light-emitting diode (OLED) with Commission Internationale de I'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.
