Abstract

The application provides an organic compound having a structure shown in formula I-1 and formula I-2 and its application as well as an organic electroluminescence device and an electronic device using the same, which belong to the technical field of organic materials. Applying the organic compound to the light-emitting layer of the organic light-emitting device can reduce the driving voltage of the device, improve the current efficiency and luminous efficiency, and greatly increase the service life of the device.

Description

technical field [0001] The application belongs to the technical field of organic materials, and specifically provides an organic compound and its application, as well as an organic electroluminescence device and an electronic device using the same. Background technique [0002] With the development of electronic technology and the progress of material science, the application range of electronic components for realizing electroluminescence or photoelectric conversion is becoming wider and wider. Such electronic components generally include a cathode and an anode oppositely arranged, and a functional layer arranged between the cathode and the anode. The functional layer is composed of multiple organic or inorganic film layers, and generally includes an energy conversion layer, a hole transport layer located between the energy conversion layer and the anode, and an electron transport layer located between the energy conversion layer and the cathode. [0003] Taking an organic...
