Description

Technical Field

[0001] This application belongs to the field of organic materials technology, and in particular relates to an organic compound and electronic components and devices containing the same. Background Technology

[0002] With the development of electronic technology and the advancement of materials science, the application range of electronic components used to achieve electroluminescence or photoelectric conversion is becoming increasingly wide. These electronic components typically include a cathode and an anode positioned opposite each other, and a functional layer disposed between the cathode and anode. This functional layer consists 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. Taking an organic electroluminescent device as an example, it generally includes an anode, a hole transport layer, an organic light-emitting layer serving as the energy conversion layer, an electron transport layer, and a cathode stacked sequentially. When a voltage is applied to the anode and cathode, an electric field is generated between the two electrodes. Under the influence of the electric field, electrons on the cathode side move towards the organic light-emitting layer, and holes on the anode side also move towards the organic light-emitting layer. Electrons and holes combine in the organic light-emitting layer to form excitons. The excitons are in an excited state and release energy outward, thereby causing the organic light-emitting layer to emit light.

[0003] The most significant issues with existing organic light-emitting diodes (OLEDs) are lifespan and efficiency. As displays become larger, driving voltages increase, necessitating improvements in both luminous and current efficiency. Therefore, it is essential to continue developing novel organic light-emitting layer materials to further enhance the performance of OLEDs. Summary of the Invention
