Abstract:
An anthrylarylene derivative having a specific structure and an organic electroluminescence device comprising an organic thin film layer which comprises at least one layer comprising at least a light emitting layer and is disposed between a cathode and an anode, wherein at least one layer in the organic thin film layer comprises the anthrylarylene derivative singly or as a component of a mixture. The device exhibits a great efficiency of light emission and has a long life. The anthrylarylene derivative has a sufficient glass transition temperature and is greatly advantageous as the light emitting material used in the above organic electroluminescence device.
