Title:
ANTHRACENE DERIVATIVE, ORGANIC ELECTROLUMINESCENT MATERIAL, LIGHT-EMITTING DEVICE, AND CONSUMER PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/065996
Kind Code:
A1
Abstract:
The present invention relates to an anthracene derivative, an organic electroluminescent material, a light-emitting device, and a consumer product. The anthracene derivative of the present invention is a novel organic electroluminescent compound having a seven-membered ring non-planar structure composed of anthracene and biphenyl, wherein the seven-membered ring anthracene derivative increases molecular steric hindrance, hinders the generation of an organic intermolecular exciton-exciton complex, improves internal quantum efficiency, and has a shorter light emission wavelength than existing compounds, and thus the efficiency and lifetime of an organic electroluminescent device containing the compound are improved; in addition, the compound has improved solubility in a solution and thus solves the problems of process productivity and cost of a conventional blue light emitting material.
