Title:
ORGANIC COMPOUND AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/125276
Kind Code:
A1
Abstract:
Provided in the present invention are an organic compound and a use thereof, the molecular bulk density thereof being improved through the design of the molecular structure, and the compound having excellent hole transport properties; the HOMO energy level of the compound can be regulated and improved to better match with an anode material, improving the hole injection and transport capabilities of the compound, which is conducive to low-voltage acquisition and significantly improves the stability of carrier transport in an electric field environment. When used as an organic electroluminescent device material, the organic compound has good film-forming properties; when used in an organic electroluminescent device, the organic compound is particularly suitable for use as a hole transport layer material and/or an electron blocking layer material, and can effectively improve the light-emitting efficiency and stability, prolong the service life, and reduce the voltage of the device, and achieve a better light-emitting effect.
