摘要：

We report the use of fluorene based copolymers containing quinoline (POF66, P1F66) and pyridine(PFPV) units as electron transporting polymers for multi-layered LEDs. Double-layer device structure combining P1F66 as electron-transporting layer with the emissive MEH-PPV showed a maximum quantum efficiency of 0.03%, which is 30 fold increased compared with ITO/MEHPPV/Al single-layer device. The ETL with the electron deficient moiety improved the LED performance by the characteristics of electron transporting as well as hole blocking between emissive layer and metal cathode.
