Title:
ORGANIC MATERIAL AND ORGANIC LIGHT EMITTING DIODE CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2021/029464
Kind Code:
A1
Abstract:
The present invention relates to a compound for an organic light emitting diode, an organic light emitting diode using same, and an electronic device comprising the organic light emitting diode. According to the present invention, it is possible to realize delayed fluorescence. In addition, the quantum efficiency of the organic light emitting diode is improved since radiationless decay is reduced due to a robust molecular structure. Moreover, the high glass transition temperature and the stability of molecules are enhanced, such that the lifespan can be improved.
