CAS Number 142289-08-5
DPVBi is a wide band gap small molecule semiconducting material, commonly used as a blue host-emitting material in OLEDs.
It has been reported that DPVBi can effectively manipulate the Schottky energy barrier between the ITO and the emitting layer, and thus significantly enhance hole-injection, current and luminance efficiencies of OLEDs, as well as their stability [1].
