Paragraph 0065-0069, (2020/04/22)
The invention discloses an organic electroluminescent compound and a preparation method thereof, and an organic electroluminescent device, and belongs to the field of chemical synthesis and photoelectric materials, wherein the structural general formula of the organic electroluminescent compound is defined in the specification, and in a formula I, L is one selected from a chemical bond, substituted or unsubstituted C6-C30 aryl and substituted or unsubstituted C3-C30 heteroaryl, X is a heteroatom, and Ar1 and Ar2 are respectively and independently selected from substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C6-C30 aryl, substituted or unsubstituted C3-C30 heteroaryl, substituted or unsubstituted C3-C30 arylamino, substituted or unsubstituted C3-C30 aliphatic amino and single ring or multi-ring formed by linking adjacent substituent groups. According to the invention, with the application of the organic electroluminescent compound as the material of the light-emitting auxiliary layer and/or hole transport layer of an organic electroluminescent device, the driving voltage of the organic electroluminescent device can be remarkably reduced, the light-emitting efficiency of the organic electroluminescent device is improved, and the service life of the organic electroluminescent device is prolonged.
