| abstract |
The invention discloses an anthracene substituted derivative and its application. The present invention relates to a class of compounds represented by formula (1), wherein: Ar 1 is selected from a hydrogen atom, a phenyl group, a naphthyl group, or Ar 1 and a phenyl group are connected via a divalent alkylene group to form a fused-ring aryl group; Ar 2 is selected from C 4 -C 20 nitrogen-containing heteroaryl groups, or Ar 2 is substituted by a nitrile group. The present invention also protects the application of such compounds in organic electroluminescent devices, especially as electron transport materials, red phosphorescent host materials in OLED devices. |
