Paragraph 0121-0122; 0130-0131; 0215-0217, (2021/12/07)
The invention provides a diamine derivative and an organic electroluminescent device thereof, and relates to the technical field of organic electroluminescent materials. The diamine derivative represented by Formula 1 contains 9 -fluorene-substituted carbazole functional group, and the hole transport region or cover layer of the organic electroluminescent device of the present invention contains the carbazole derivative of Formula 1. The diamine derivative represented by the formula 1 has better hole transport performance and stability, and the prepared organic electroluminescent device containing the diamine derivative of the formula 1 in the prepared hole transport region exhibits high luminous efficiency. A longer service life and is a lower driving voltage. In addition, the diamine derivative of the formula 1 is also a better cover layer material; the prepared cover layer contains the diamine derivative of the formula 1; the organic electroluminescent device has high luminous efficiency and long service life.
