We synthesized a new polymer that carries the electron-donating alkoxy group and carbazole group attached to the phenylene ring and fabricated mono and bilayer devices consisting of electron transporting tris(8-qunolinolato)aluminum(II) (Alq3) and the polymer layers. The monolayer device showed low turn-on voltage and high external quantum efficiency(0.01%). Also external quantum efficiency of its bilayer device was 0.23%.
