Document Type and Number:
WIPO Patent Application WO/2023/093311
Kind Code:
A1
Abstract:
The present invention relates to a luminescent material made of a platinum complex having an NNCN tetradentate ligand, and an application thereof. The platinum complex has a structure of chemical formula (I). When applied to an organic light-emitting diode, the compound has a low driving voltage and high light-emitting efficiency, can significantly prolong the service life of the device, and has the potential to be applied to the field of organic electroluminescent devices. The present invention further provides an organic electroluminescent device, which comprises a cathode, an anode and an organic layer. The organic layers are one or more of a hole injection layer, a hole transport layer, a light-emitting layer, a hole blocking layer, an electron transport layer and an electron injection layer. At least one of the organic layers contains a compound represented by structural formula (I).
