Title:
ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/073594
Kind Code:
A1
Abstract:
[Problem] To provide, as an organic-EL-device material with high efficiency and high durability, an organic-EL-device material that is superior in terms of positive-hole injection/transport performance, electron-blocking capability, and stability and durability in a thin film state and also to provide an organic electroluminescent device having high efficiency, low drive voltage, and long-term service life by combining the aforementioned material with various types of organic-electroluminescent-device materials that are superior in terms of positive-hole and electron injection/transport performance, electron-blocking capability, and stability and durability in a thin film state, so that the properties of each of the materials can be exhibited effectively. [Solution] An organic electroluminescent device according to the present invention has at least a positive electrode, a positive-hole transport layer, a light-emitting layer, an electron transport layer, and a negative electrode in that order and is characterized in that the positive-hole transport layer contains an arylamine compound represented by general formula (1).
