Abstract

A thermally activated delayed fluorescent material, preparing method thereof, and an organic electroluminescent device are disclosed. The organic electroluminescent device includes an anode layer, a cathode layer, and a light-emitting layer disposed between the anode layer and the cathode layer. The light-emitting layer includes a thermally activated delayed fluorescent material. A structural formula of the thermally activated delayed fluorescent material is shown in the following structural formula I: and R-Rare electron donor units.
