It is an object of the present invention to provide a novel triazole derivative. Further, it is another object of the present invention to provide a light-emitting element having high luminous efficiency with the use of the novel triazole derivative. Moreover, it is still another object of the present invention to provide a light-emitting device and electronic devices which have low power consumption. A light-emitting element having high luminous efficiency can be manufactured with the use of a triazole derivative which is a 1,2,4-triazole derivative, in which an aryl group or a heteroaryl group is bonded to each of 3-position, 4-position, and 5-position, and in which any one of the aryl group or heteroaryl group has a 9H-carbazol-9-yl group.
本发明的一个目的是提供一种新颖的三唑衍生物。此外,本发明的另一个目的是利用这种新颖的三唑衍生物提供具有高发光效率的发光元件。此外,本发明的另一个目的是提供具有低功耗的发光装置和电子设备。利用一种1,2,4-三唑衍生物可以制造具有高发光效率的发光元件,其中芳基或杂环芳基分别连接到3位、4位和5位,并且芳基或杂环芳基中的任何一个具有9H-咔唑-9-基团。
