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.
提供了一种新的蒽衍生物,其具有特定结构,其中苯并呋喃或苯并噻吩通过芳基烷基与蒽相结合,以及含有该蒽衍生物的有机电致发光器件材料和发光材料。还提供了一种有机电致发光器件,包括由至少一个发光层组成的一个或多个层的有机薄膜层,在阴极和阳极之间插入有机薄膜层,其中有机薄膜层中的至少一层单独或作为混合物的组分含有该蒽衍生物。该有机电致发光器件具有高的发光效率和长寿命,可以通过该蒽衍生物实现。
