The present invention relates to a novel OLED material, and the OLED material has the molecular structure shown in formula (I): Wherein, Ar 1 and Ar 2 are independently selected from C6-C60 aryl groups, C6-C60 heteroaryl groups containing N, S, O, and C7-C61 aralkyl groups, and Ar 1 and Ar 2 are the same or different. The OLED material provided by the present invention has a simple preparation method and good thermal stability; the organic electroluminescence device produced by using the OLED material provided by the present invention as a functional layer has good photoelectric performance; the material of the present invention is used as a doping material , OLED devices with BH-1 as the main material, the current density is 20mA/cm 2 , the LT95 lifetime of the device can reach 300～346(Hr)@5000nits, and the current efficiency is 7.89～8.49cd/A. |
