4,4'-Bis(2,2-diphenylvinyl)-1,1'-biphenyl Usage And Synthesis

Classification

Hole-injection materials, Hole-transporting materials, Blue light-emitting materials, Host materials, Organic light-emitting diodes (OLEDs), Organic electronics.

Applications

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.
