In this article, we review recent developments of modern host materials for green phosphorescent OLEDs. We show that optical emitter orientation can be enhanced significantly by tailored hosts, resulting in an increased device efficiency. Beyond efficiency, matching the system to applied is shown key optimum performance. addition maximized classical performance parameters, hosts need fulfill further requirements. Prominent examples are tuning OLED stack capacitance or development stable premixed systems, enabling evaporation multiple from one crucible.
