The electroluminescent material, the preparation method of the electroluminescent material, and the light-emitting device provided by the embodiments of the present application, the electroluminescent material is generated by reacting the first reactant and the second reactant, and the electroluminescent material adopts a low three-wire The cyclic bipyridone at the state level is used as the acceptor unit, and the charge transfer property between the acceptor unit and the donor unit is further enhanced by utilizing the strong electron-withdrawing property of the pyridine group, thereby realizing high-efficiency, deep red light electroluminescent material. |
