摘要:
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.

摘要:
Novel materials are provided, having a single phenyl or a chain of phenyls where there is a nitrogen atom on each end of the single phenyl or chain of phenyls. The nitrogen atom may be further substituted with particular thiophene, benzothiophene, and triphenylene groups. Organic light-emitting devices are also provided, where the novel materials are used as a hole transport material in the device. Combinations of the hole transport material with specific host materials are also provided.
