Abstract
Hole injection layer and charge generation layer containing a truxene based compound are disclosed for organic electronic devices. By applying the truxene based compound for the hole injection layer, low driving voltage, high efficiency and long lifetime of the device can be achieved. In addition, a P-type charge generation layer comprising the truxene based compound can be used in tandem OLEDs structure and can further improve the voltage, efficiency and lifetime of the device.
