Abstract

The invention relates to the field of electroluminescence, and discloses a compound and an organic electroluminescent device. The structural formula of the compound is shown as a formula (I), so that the driving voltage and the current efficiency of the electroluminescent device are reduced, and meanwhile, the invention provides a compound capable of preparing a transmission layer of the electroluminescent device by using a solution method.

Description

Technical field [0001] The present application relates to the field of electroluminescent light, and more particularly to a compound and an organic electroluminescent device. Background technique [0002] Currently, an organic electroluminescence (OLED) has been applied in the fields of smartphones, tablets, and further expansion to large-sized applications such as television. In the past 30 years of development, people have developed a variety of performance-based OLED materials, and accelerate the commercialization of OLED's commercialization through the optimization of the device structure, and optimize the life, efficiency of the device. OLED has been widely used in the field of display and lighting. [0003] However, since there is a huge gap between the external quantum efficiency and the internal quantity efficiency, it is greatly constrained in the development of OLED, one of the most important factors is that the efficiency of the device has not reached the ideal level. ...
