Abstract

Two deep blue emitting materials PPI-PPITPA and PPI-PPIPCz with dual carrier transport properties and small singlet-triplet splitting features are designed and synthesized. PPI-PPITPA and PPI-PPIPCz were used not only as non-doped emitting layers to fabricate highly efficient deep blue OLEDs, but also as hosts to construct high performance green, yellow and red phosphorescent OLEDs.
