Organic Material Containing Oligophenylene Skeleton and Light-Emitting Device Using the Same

摘要

[Object] To provide a wide band-gap material capable of forming a stable amorphous thin film and an organic electroluminescent device using such a compound and having a high light emission efficiency. [Solution] It has been found that a novel oligophenylene derivative, which is applicable as an organic electroluminescent material, can be produced efficiently using a cross-coupling reaction. It has also been found that a highly-efficient blue phosphorescent light-emitting device can be produced using this compound. The present invention is based on these findings.
