Title:
ORGANIC ELECTROLUMINESCENT COMPOUND, PREPARATION THEREFOR, APPLICATION THEREOF, AND ELECTROLUMINESCENT DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/109886
Kind Code:
A1
Abstract:
The present invention discloses an organic electroluminescent compound having a structural formula represented by formula (I). The organic electroluminescent compound has good chemical stability and a high glass transition temperature and decomposition temperature, and is an OLED material with excellent performance. The synthesis of the material involves a simple route and is easy to carry out, has high reaction yields, can reduce preparation costs of OLED materials, and has good industrialization prospects. The OLED material can be used in organic electroluminescent devices as a dopant for a light-emitting layer. An organic electroluminescent diode prepared using the OLED material can achieve effects of high brightness, high efficiency, and low voltages, can effectively avoid screen dark spots, and has superior performance.
