ELECTRO LUMINESCENCE ASSEMBLY CONTAINING N-ALKYL-2,2'-IMINO-BIS-(8-HIDROXIQUINOLINE)-METAL LIGAND

摘要

PURPOSE: A EL assembly is provided to prevent the surface of formerly cast layer form being solved in the process of making later casting. CONSTITUTION: In the assembly comprising substrate, anode, electro luminescence device and cathode, and at least one of the two electrode is transparent in the band of visible light and the electro luminescence device include one or more region selected from the set of sequentially arrayed hall injection region, hall carrying region, electro luminescence region, electron carrying region and electron injection region. each of the existing region may play the roll of above mentioned other region. the assembly is characterized by the fact of containing N-alkyl-2.2'-imino-bis-(8-hidroxiquinoline)-metal ligand.
