DPVBi, a blue host-emitting material in OLEDs

Enhances hole-injection, current and luminance efficiencies of OLEDs

DPVBi, 4,4 -bis(2,2 -diphenylvinyl)-1,1 -diphenyl, 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].
