The development of high efficient and color pure blue emitting materials is most important issue.
In this presentation, I will report various design stratergies for the development of high efficient and color pure blue emitting materials by using phosphorescence, TADF, and fluoresence with TTA.
Especially, the new blue phosphorescent materials showed over 30 %, blue TADF materials showed over 27 % , and blue fluorescence materials showed over 14%.
