We report on the synthesis and electroluminescence characteristics of a new green-emitting material, 3, 7-bis (1-(biphenyl-4-yl) benzimidazol-2-yl) 10-methylphenothiazine (PhBBMP) containing the electron-donating phenothiazine core and the electron-accepting biphenyl benzimidazole substituent. An optimized OLED device with the structure of [ITO/NPB (40 nm)/PhBBMP (30 nm)/BCP (10 nm)/TPBI (30 nm)/LiF (1 nm)/Al (100 nm)] exhibited a ...
