Zusammenfassung: | An object of the present invention is to provide a material for organic EL elements, the material being excellent in hole injecting/transporting performance, electron-blocking capability, stability in the form of a thin film, and durability. Another object of the present invention is to provide an organic EL element having high efficiency, a low driving voltage, and a long lifespan, by combining the aforementioned material with various materials for organic EL elements, the materials being excellent in hole/electron injecting/transporting performance, electron-blocking capability, stability in the form of a thin film, and durability, such that the properties of the individual materials can be effectively exhibited. Focusing on the finding that a triarylamine compound having a specific structure is excellent in hole injecting/transporting capability, stability in the form of a thin film, and durability, a specific arylamine compound was selected and used as a material for a hole-transporting layer to produce an organic EL element, and thus, the present invention has been accomplished. |
