Electroluminescent devices containing N-alkyl-2,2'-imino-bis-(8-hydroxy-quinoline) metal complexes

摘要

An electroluminescent arrangement, composed of a substrate, an anode, an electroluminescent element and a cathode, wherein at least one of the two electrodes in the visible spectral range is transparent, and the electroluminescent element has one or more zones selected from the group consisting of hole-injecting zone, hole-transporting zone, electroluminescent zone, containing the electron-transporting zone and an electron injection zone in the order mentioned, each of the zones present may also take over tasks of the other zones mentioned, characterized in that the electroluminescent element comprises an N-alkyl-2,2'-imino-bis- (8-hydroxyquinoline ) -metal complex contains.
