摘要：
The present invention relates to an organic electroluminescent material, an organic electroluminescent device, and a method for preparing the organic electroluminescent device. Due to comprising an organic compound A with 3.0 eV>ET≥2.0 eV and a compound B of M(LA)x(LB)y(LC)z, the organic electroluminescent material of the present invention has the advantages of an increased luminescence lifetime and/or a reduced operating voltage on the basis of maintaining other electronic properties at a certain level.
