Title:
CARBAZOLE DERIVATIVE AND USE THEREOF IN OLED
Document Type and Number:
WIPO Patent Application WO/2024/012522
Kind Code:
A1
Abstract:
Provided are a carbazole derivative and a use thereof in an organic light-emitting diode (OLED). The carbazole derivative has a fused carbazole structure, has a high triplet energy level, and increases conjugation of a carbazole parent nucleus, thereby improving the thermal stability of a material and the capability of transporting carriers. Use of the carbazole derivative in an organic electroluminescent element can significantly reduce the driving voltage, improve the luminous efficiency and prolong the service life. The structural formula of the carbazole derivative is as shown in formula (I).
