咔唑衍生物和使用该咔唑衍生物的发光元件以及发光器件
摘要：
本发明的目的是提供一种具有极佳的空穴注入性质和空穴传输性质的材料，以及提供使用具有极佳的空穴注入性质和空穴传输性质的材料的发光元件和发光器件。本发明提供了通式(1)所示的咔唑衍生物。本发明的咔唑衍生物具有极佳的空穴注入性质。通过使用本发明的咔唑衍生物作为发光元件的空穴注入层的空穴注入材料，可以减小驱动电压。另外，通过将所述材料应用于发光元件或发光器件，可以获得较低的驱动电压、提高发光效率、延长寿命和提高可靠性。
摘要（英）：

It is an object of the present invention to provide a material which is excellent in a hole injecting property and a hole transporting property, and to provide a light emitting element and a light emitting device using a material which is excellent in a hole injecting property and a hole transporting property. The present invention provides a carbazol derivative represented by a general formula (1). The carbazol derivative according to the present invention is excellent in the hole injecting property. By using the carbazol derivative according to the present invention as a hole injecting material for a hole injecting layer of a light emitting element, a driving voltage can be reduced. In addition, a lower driving voltage, improvement of the luminous efficiency, a longer life time, and higher reliability can be realized by applying the material to a light emitting element or a light emitting device.
