Abstract
Provided are a novel anthracene derivative of a specific structure in which benzofuran or benzothiophene is bonded to anthracene through an arylene group, a material for an organic electroluminescence device and a light emitting material for an organic electroluminescence device each containing the anthracene derivative, and an organic electroluminescence device including an organic thin film layer formed of one or plural layers including at least a light emitting layer, the organic thin film layer being interposed between a cathode and an anode, in which at least one layer of the organic thin film layer contains the anthracene derivative alone or as a component of a mixture. The organic electroluminescence device has high luminous efficiency and is capable of emitting light with a long lifetime, and the device can be realized by the anthracene derivative.
