Title:
DIVALENT PLATINUM COMPLEX HAVING HIGH COLOR PURITY
Document Type and Number:
WIPO Patent Application WO/2023/082898
Kind Code:
A1
Abstract:
The present invention relates to a divalent platinum complex having high color purity, comprising a structure of chemical formula (I). The compound is applied to an organic light-emitting diode, has relatively low driving voltage and relatively high luminous efficiency, is narrow in full width at half maximum, and has the potential to be applied to the field of organic electroluminescent devices; and the higher the color purity is, the better the quantum efficiency can be obtained. The present invention further provides an organic electroluminescent device, comprising a cathode, an anode, and an organic layer. The organic layer is 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 layer in the organic layer contains a compound represented in structural formula (I).
