Title:
TETRADENTATE PLATINUM COMPLEX LIGHT-EMITTING MATERIAL CONTAINING SPIRO STRUCTURE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/202471
Kind Code:
A1
Abstract:
A tetradentate platinum complex containing a spiro structure and use of said complex in an organic light-emitting diode. The tetradentate platinum complex is a compound with a structure represented by chemical formula (I), and the material has a high luminescence quantum yield and a short excited state lifetime. When applied to an organic light-emitting diode, the material has good luminous efficiency and device stability. Also provided is an organic electroluminescent device, comprising a cathode, an anode, and organic layers. 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, and at least one of the organic layers contains the compound represented by structural formula (I).
