摘要:
The triarylamine compound having a specific structure in the present invention is excellent in hole injection/transport ability, stability and durability of thin film. By selecting the triarylamine compound having a specific structure as the material for the hole transport layer, holes injected from the anode side can be efficiently transported. Furthermore, various organic EL devices combining luminescent materials having a specific structure or the like exhibit good device characteristics.
