Title:
PLATINUM COMPLEX LIGHT-EMITTING MATERIAL BASED ON CARBAZOLE MODIFICATION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/109722
Kind Code:
A1
Abstract:
A platinum complex light-emitting material based on carbazole modification and an application thereof. A platinum complex is a compound having a structure as represented by chemical formula I. An aza-condensed ring contained in this series of materials spin density distribution accelerates a triplet radiative transition speed by changing spin density distribution. According to the series of materials, by means of carbazole modification, molecular aggregation is inhibited, and an intermolecular π-π effect is reduced; and the light-emitting efficiency of molecules is also improved while improving the thermal stability of the molecules. The compound is applied to an organic light-emitting diode, so that a low driving voltage and high light-emitting efficiency are achieved, and the light-emitting efficiency of the material and the service life of a device can be significantly improved. The present invention has the potential of being applied in the field of organic electroluminescent devices.
