    • An electroluminescent element which comprises host materials and guest materials in a part of an electroluminescent layer, and which is superior in device characteristics such as luminous efficiency and luminous characteristics to those of the conventional electroluminescent element is provided. According to the present invention, device characteristics (luminous efficiency, luminous characteristics, or the like) of an electroluminescent element is improved by using host materials and guest materials which have a common skeleton (represented by the following general formula 1) for an electroluminescent layer interposed between a pair of electrodes in the electroluminescent element. wherein R1 is a hydrogen atom, or the like, R2 to R5, each of which may be the same or different, are individually a hydrogen atom, or the like, and Ar1 is an aryl group which may have a substituent, or the like.
    • 提供了一种电致发光元件,其包含在电致发光层的一部分中的主体材料和客体材料,并且其设备特性如发光效率和发光特性优于常规电致发光元件。 根据本发明,通过使用具有共同骨架(由以下通式1表示)的主体材料和客体材料用于电致发光层来提高电致发光元件的器件特性(发光效率,发光特性等) 插入在电致发光元件中的一对电极之间。 其中R1是氢原子等,R2〜R5各自可以相同或不同,分别为氢原子等,Ar1为可具有取代基的芳基等 。
