Title:
FLUORENE DERIVATIVE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/151394
Kind Code:
A1
Abstract:
The present invention relates to the technical field of organic electroluminescent materials, and in particular, to a fluorene derivative and a use thereof. The structural formula of the fluorene derivative is shown in formula (I). The fluorene derivative shown in formula (I) provided by the present invention increases the rigidity of triarylamine, has a high triplet energy level, and improves the thermal stability and carrier transport capability of materials. When the fluorene derivative is applied to an organic electroluminescent element, the driving voltage can be remarkably reduced, the light-emitting efficiency can be improved, and the service life can be prolonged.
