mCPPO1, 9-(3-(9H-Carbazol-9-yl)phenyl)-3-(diphenylphosphoryl)-9H-carbazole, has a bipolar character with an electron rich 1,3-di(9H-carbazol-9-yl)benzene core unit and an electron deficient diphenylphosphine oxide attachment.
mCPPO1 is an extended family member of mCP with a higher glass transition temperature (Tg = 114.7 °C), and can be used as a phosphorescent host material for blue, green and red organic light emitting diodes. The bipolar charge transport properties of mCPPO1 can effectively balance holes and electrons in the emitting layer, improving device performance.
