Highly Efficient Blue Electroluminescence from Poly(phenylene ethynylene) via Energy Transfer from a Hole-Transport Matrix

Blue poly(phenylene ethynylene) (PPE) electroluminescence (EL, see Figure) is observed in a hybrid organic 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 uti...

Zusammenfassung:Blue poly(phenylene ethynylene) (PPE) electroluminescence (EL, see Figure) is observed in a hybrid organic 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.
