Use of gadolinium (iii) - chelates as luminescent materials in organic light-emitting diodes (oleds)

摘要

The present invention relates to the use of gadolinium (iii) - is a complex of the formulae i and ii as emitter molecules in organic light-emitting diodes (oleds), wherein the radicals in the claims and in the description are defined. Furthermore, the present invention relates to the use of the gadolinium (iii) - complexes as light - emitting layer in oleds, a light - emitting layer containing at least one gadolinium (iii) - complex, an oled, containing these light - emitting layer, as well as devices, which contain an inventive oled.
