NEW ELECTRON-TRANSPORTING AND HOLE-BLOCKING MATERIAL BASED ON HEXAATRIPHENYLENES WITH SIX AROMATIC GROUPS

摘要

Hexaazatriphenylenes HAT-ph with six phenyl and HAT-biph with six biphenyl functional groups at the peripheral positions were designed, and prepared as electron-transporting as well as hole-blocking materials in OLEDs. When HAT-ph and HAT-biph were used as the electron-transporting layer in suitable OLED devices, good OLED performance was achieved.
