Benzimidazole/Amine‐Based Compounds Capable of Ambipolar Transport for Application in Single‐Layer Blue‐Emitting OLEDs and as Hosts for Phosphorescent Emitters

A bolt from the blue? Compounds like that shown containing benzimidazole and arylamine units exhibit intriguing ambipolar carrier-transport properties and can be used to fabricate single-layer blue-emitting electroluminescent devices with very promising performances (see picture, ITO=indium tin oxide).
