We designed and synthesized novel p-type host by 1-step buckwald reaction. And synthesized p-type host was mixed with 2,8-bis(4,6-diphenyl-1,3,5-triazin-2-yl)dibenzo[b,d]furan (DBFTrz). The mixed pair showed broad and red-shifted emission. To evaluate mixed host, the device was fabricated. For comparison, tris(4-(9H-carbazol-9-yl)phenyl)amine (TCTA):DBFTrz host device was fabricated. As a result, the new mixed host device showed similar external quantum efficiency and extended operational lifetime about 11 times. |
