Electroluminescent devices were fabricated using a holetransporting polymer, poly[ N ‐[ p ‐ N ′ ‐phenyl‐ N ′‐[1,1′‐biphenyl‐4′‐[ N ″‐phenyl‐ N ″‐(2‐methylphenyl)amino]‐4‐amino]]phenyl methacrylamide] (PTPDMA), and tris(8‐quinolinolato)aluminum(III) complex, Alq, as the hole transport layer and the emitter layer, respectively. A device structure of glass substrate/indium–tin–oxide/PTPDMA/Alq/Mg:Ag was employed. Hole injection from the electrode through the PTPDMA layer to the Alq layer and concomitant electroluminescence from the Alq layer were observed. Bright green luminescence with a luminance of 20,000 cd/m 2 was obtained at a drive voltage of 14 V.
