| abstract |
The present invention relates to a kind of organic luminescent material as shown in formula (I), wherein: Ar 1 -A 8 are independently selected from H, C6-C30 substituted or unsubstituted aromatic hydrocarbon groups, C6-C30 substituted or Unsubstituted fused ring aromatic hydrocarbon group, C6~C30 substituted or unsubstituted fused heterocyclic group, five-membered, six-membered heterocyclic or substituted heterocyclic ring, triarylamino group, aryl ether group, One of C1-C12 substituted or unsubstituted aliphatic alkyl groups. The present invention also protects the application of such compounds in organic electroluminescent devices, especially as hole injection materials, hole transport layer materials, fluorescent host materials or light emitting materials in OLED devices. |
