-
Paragraph 0095-0098, (2021/06/21)
The invention discloses an organic light-emitting auxiliary layer material, a preparation method and application thereof, and an organic electroluminescent device, and relates to the field of organic photoelectric materials. The chemical structural formula of the organic light-emitting auxiliary layer material is shown in the specification, wherein R1, R2, R3 and R4 are independently selected from hydrogen, deuterium, halogen, cyano, substituted or non-substituted alkyl, substituted or non-substituted aryl, substituted or non-substituted heteroaryl and a substituted or non-substituted fused ring group, and Ar1 and Ar2 are respectively and independently selected from a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, a substituted or unsubstituted fused ring group and a substituted or unsubstituted spiro group. The organic light-emitting auxiliary layer material has efficient electron blocking capability and hole transport capability, a device prepared from the organic light-emitting auxiliary layer material has high light-emitting efficiency, low driving voltage and high heat resistance, the color purity of the device can be improved, and the service life of the device can be prolonged. The organic light-emitting auxiliary layer material can be widely applied to organic electroluminescent devices.
