Title:
ORGANIC ELECTROLUMINESCENT COMPOUND, PREPARATION METHOD THEREFOR AND ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/134138
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of luminescent materials, and relates in particular to an organic electroluminescent compound, a preparation method therefor and an organic electroluminescent device. In order to solve the existing problems in traditional hole transport materials to obtain an ideal material, the present disclosure proposes a solution to introduce arylamine and a heterocyclic ring at the 9-position of heteroanthracene. By means of introducing arylamine, hole injection/transport capabilities are obtained, as well as high power efficiency and long service life; by means of introducing a heterocyclic ring, an appropriate glass transition temperature is obtained, thereby obtaining a high-quality organic electroluminescent material. Devices made from the compound provided by the present disclosure have excellent current efficiency and power efficiency and have a long service life. The preparation method for an organic electroluminescent compound provided by the present disclosure is simple and easy to implement, has a high yield, and is suitable for industrial production.
