The invention relates to a boron-containing organic electroluminescence material, a preparation method and application thereof, and belongs to the technical field of organic electroluminescence. In the present invention, a new type of boron-containing organic electroluminescent material is synthesized through multi-step ring buckle reaction. Such molecules have suitable molecular weights (400-1200), wide energy gaps (both in The higher glass transition temperature Tg (above 120°C) is suitable as the host material of the light-emitting layer; the fabricated organic electroluminescent device has better current efficiency and longer device life. |
