Organic electroluminescent devices were fabricated using a poly(arylene ether sulfone)‐containing tetraphenylbenzidine (PTPDES) and tris(8‐quinolinolato)‐aluminum(III) complex, Alq, as the hole transport layer and the electron‐transporting emitter layer, respectively. A device structure of glass substrate/indium—tin oxide (ITO)/PTPDES/Alq/Mg : Ag was employed. Hole injection from ITO through the PTPDES layer to the Alq layer and concomitant electroluminescence from the Alq layer were observed. Bright green light with a luminance of 14,000 cd/m 2 was observed at a drive voltage of 14 V, indicating that the polymer possesses a high hole mobility and a high electron‐blocking capability.
