We study the role of green phosphorescent hosts in determining OLED performance. Key aspects are mixture optimization, premixed hosts with high performance stability over the entire crucible filling range, deuteration of different host components, adaptation of hosts to dopants, host impact on optical emitter orientation and tuning the device capacitance.
