METAL COMPLEXES AND ELECTROLUMINESCENT DEVICES COMPRISING THESE METAL COMPLEXES

摘要

The present invention relates to a method for preparing a metal complex comprising a metal atom of Groups 13 to 15 and at least one ligand, wherein the ligand comprises at least one anionic ligand having at least one oxygen and / or nitrogen atom to which a metal atom is coordinated, A method for producing the same, and a use thereof in an electronic device, particularly an organic electroluminescent device, so-called OLED (OLED = organic light emitting diode). Further, the present invention also relates to an organic electroluminescent device comprising these metal complexes.
