A bipolar host designed using indolocarbazole as a bipolar moiety was developed by coupling two indolocarbazole moieties via a phenyl linker. The indolocarbazole derived hosts could carry holes and electrons in the emitting layer, functioning as bipolar hosts in the green phosphorescent organic lightemitting diodes. The linker based molecular design was superior to the directly coupled molecular design to match carrier balance for high quantum efficiency in the green phosphorescent devices.
