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.
提供了一种新型材料,包含一个苯基或苯基链,其中单个苯基或苯基链的每个末端均有一个氮原子。该氮原子可能进一步被特定的噻吩、苯并噻吩和三苯基烯基团取代。还提供了有机发光器件,其中新型材料用作器件中的空穴传输材料。还提供了空穴传输材料与特定主体材料的组合。
