[OLEDp1-5] Wide-bandgap bipolar material with high thermal stability
Organic Light Emitting Diode, Bipolar Host, Phosphorescent
A new organic compound was synthesized with bipolar carrier mobility, high singlet/triplet energies, and high thermal stability (193 oC) with suitable molecular design. As the host of blue phosphorescent OLED, it shows maximum current efficiency, power efficiency, and external quantum efficiency of 58.7 cd/A, 59.3 lm/W, and 28.6%, respectively.
