Application

4,4'-Bis(2,2-diphenylvinyl)biphenyl, purified by sublimation, serves as a key component in organic light-emitting diodes (OLEDs) due to its nature as a wide band gap small molecule semiconducting material. This light yellow powder is particularly effective as a blue host-emitting material, significantly enhancing the performance of OLEDs. It achieves this by effectively lowering the Schottky energy barrier between the indium tin oxide (ITO) and the emitting layer. As a result, it improves hole-injection, current efficiency, and luminance efficiency, while also contributing to the overall stability of the devices.
