, (2011/04/18)
Devices containing a particular combination of organic compounds are provided. In particular, the devices contain twisted aryl compounds having extended conjugation (i.e., the twisted aryl is substituted with an additional aryl group) in combination with dibenzothiophene or dibenzofuran containing host materials. The organic light emitting devices may provide improved stability color, lifetime and manufacturing. Compounds containing a twisted aryl having extended conjugation are also provided.
