Blue thermally active delayed fluorescent materials based on fluoroboron complexes and their applications |
| abstract |
The present invention discloses a kind of acceptor-acceptor-donor type (A 1 -A 2 -D) dual-acceptor blue thermally active delayed fluorescent material (TADF) based on fluoroboron complex and its application. By introducing boron atoms into the molecule to construct a fluorine-boron complex, the energy level difference between the singlet state and the triplet state of the molecule can be effectively reduced, the reverse intersystem crossing rate of the molecule can be improved, and the luminous efficiency of the material can be enhanced. Using these materials as dopants of the light-emitting layer, organic electroluminescent devices were prepared by solution method, and the maximum external quantum efficiency as high as 20.1% was obtained. This kind of molecule is simple and efficient, and provides a research idea for designing efficient blue TADF materials. |
