The present invention relates to an organic electroluminescent material, which has the structure shown in general formula I. The novel organic electroluminescent material provided by the present invention is centered on dibenzofuran. Since dibenzofuran is a good electron transport unit, the material has both hole transport properties and electron transport properties, and can effectively transmit the light-emitting layer. It also has a high triplet energy level, which can effectively prevent the energy from being transferred back to the host material during the light-emitting process, thereby improving its light-emitting efficiency. |
