Abstract

Disclosed are an organometallic complex comprising a new six-membered N-heterocyclic ligand, and an application thereof in an organic electronic device, especially in a phosphorescent organic light-emitting diode. The present invention further relates to an organic electronic device comprising the organometallic complex according to the present invention, especially an organic light-emitting diode, and an application thereof in display and illumination technology. In the present invention, the device structure is optimized and the concentration of the metal complex in the substrate is changed, so that the device achieves the optimal performance, and an OLED device having high efficiency, high luminance and high stability is achieved, thereby providing a better choice of materials for full-colour display and illumination application.
