An efficient energy transfer from an exciplex between a sulfone and an arylamine derivatives to a blue phosphorescent emitter enables OLED performances among the best, of over 50 lm W(-1) at 100 cd m(-2) . The formation of the exciplex realizes a barrier-free hole-electron recombination pathway, thereby leading to high OLED performances with an extremely low driving voltage of 2.9 V at 100 cd m(-2) .
一种高效的能量转移，即从砜和芳胺衍生物之间的激基复合物到蓝色磷光发射器，使得 OLED 的性能达到最佳水平，在 100 cd/m²时超过 50 lm/W。激基复合物的形成实现了无势垒的空穴-电子复合途径，从而导致了极低的驱动电压（在 100 cd/m²时为 2.9 V）和极高的 OLED 性能。
