Abstract
A bisanthracene derivative having a specific structure and an organic electroluminescence device having an organic thin film layer which has one layer or a plurality of layers including at least a light emitting layer, and is disposed between a cathode and an anode and contains the bisanthracene derivatives singly or as a component of a mixture. The organic electroluminescence device exhibits a great efficiency of light emission in a region including a high luminance region and has a long life, and the bisanthracene derivative realizes the device.
