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.
提供了含有特定有机化合物组合的设备。特别是,这些设备包含扭曲芳基化合物,其具有扩展的共轭(即,扭曲芳基被替代为另一个芳基基团),与含有二苯并噻吩或二苯并呋喃的主体材料相结合。有机发光器件可能提供改善的稳定性、颜色、寿命和制造工艺。还提供了含有扩展共轭的扭曲芳基的化合物。
