INDOLE DERIVATIVE, ORGANIC ELECTROLUMINESCENT ELEMENT, DISPLAY DEVICE, AND LIGHTING DEVICE

WIPO Patent Application WO/2023/207992

A1

The present invention relates to an indole derivative, an organic electroluminescent element, a display device, and a lighting device. The indole derivative of the present invention has a relatively high triplet level and a high glass transition temperature, and is suitable for being used as a material for the organic electroluminescent element. The material for the organic electroluminescent element containing the indole derivative has the characteristics of low starting voltage, high luminous efficacy, and high luminance. In addition, the indole derivative of the present invention has good thermal stability and film-forming performance, and is applied to the material for the organic electroluminescent element, the organic electroluminescent element, the display device, and the lighting device, such that the service life can be prolonged, thereby reducing the manufacturing costs of the material for the organic electroluminescent element, the organic electroluminescent element, the display device, and the lighting device.
