Abstract

In this paper, we developed a series of novel arylamino-containing spiro triplet state host materials for green and blue phosphorescent emitters. With high enough energy gap and compatible HOMO, LUMO levels, we demonstrated the green PHOLED with a low driving voltage of 2.5 V and a high power efficiency of 38.5 lm/W. We also demonstrated blue PHOLED with a very low driving voltage of 3.0 V and a current efficiency of 9.2 cd/A.
