Abstract

Electroluminescent assembly comprising a substrate, an anode, an electroluminescent element and a cathode, where at least one of the two electrodes is transparent in the visible spectral region and the electroluminescent element contains one or more zones selected from the group consisting of hole injection zone, hole transport zone, electroluminescent zone, electron transport zone and electron injection zone in the stated order, where each of the zones present can also assume functions of the other zones mentioned, characterized in that the electroluminescent element contains an N-alkyl-2,2'-imino-bis-(8-hydroxyquinoline)-metal complex.
