Late-News Poster: New Blue Phosphorescent Host for High-efficiency White OLED

摘要

A new blue phosphorescent host with an electron transporting dibenzothiophene molecular skeleton connected to hole transporting carbazolyl moiety has been developed. Using this material, an all-phosphorescent white OLED with a high power efficiency of 60 lm/W, a low driving voltage of 3.6V and a color-rendering index of 75 at practical brightness of 1000 cd/m~2 can be achieved.
