Application

4,4'-Bis(2,2-diphenylvinyl)biphenyl is a light yellow powder that serves a critical role as a wide band gap small molecule semiconductor. This material is predominantly utilized as a blue host-emitting substance in organic light-emitting diodes (OLEDs). Its unique properties allow it to effectively adjust the Schottky energy barrier between the indium tin oxide (ITO) and the emitting layer. This adjustment substantially improves the hole-injection capabilities, current efficiency, and luminance efficiency of OLEDs while also significantly enhancing their stability.
