Definitions
- the present application relates to the field of display, and in particular to an organic compound, a mixture, a composition, an organic light-emitting device and a display panel.
- organic electroluminescent elements such as OLED (Organic Light-Emitting Diode) usually have an anode, a cathode and an organic layer between the two, and use the organic matter in the organic layer to convert electrical energy into light energy, thereby realizing organic electroluminescence.
- OLED Organic Light-Emitting Diode
- the organic layer is often multi-layered, and the organic matter in each layer is different.
- the organic layer mainly includes a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, etc.
- a voltage is applied between the anode and the cathode of the organic electroluminescent element, the anode injects holes into the organic layer, and the cathode injects electrons into the organic layer.
- the injected holes meet with the electrons to form excitons, and the excitons emit light when they transition back to the ground state, thereby realizing the luminescence of the organic electroluminescent element.
- Organic electroluminescent elements have the characteristics of autonomous luminescence, high brightness, high efficiency, low voltage drive, wide viewing angle, high contrast and high response. Therefore, organic electroluminescent devices have broad application prospects.
- organic electroluminescent elements using fluorescent materials have the characteristics of high reliability, but under electrical excitation, due to the branching ratio of the singlet excited state and the triplet excited state of the exciton is 1:3, the internal electroluminescent quantum efficiency will be limited to less than 25%, while organic electroluminescent elements using phosphorescent materials can achieve almost 100% internal electroluminescent quantum efficiency.
- phosphorescent materials usually use metal complexes containing iridium and platinum, the raw materials are expensive and the synthesis is complicated, and phosphorescent organic electroluminescent elements will also produce a Roll-off effect, that is, the luminous efficiency decreases rapidly with the increase of current or brightness, which limits its application under high brightness.
- the existing technology is usually based on various material combinations of organic compounds, such as composite excited state materials, thermally activated delayed fluorescence (TADF) materials, etc., trying to use reverse internal conversion to achieve high efficiency comparable to phosphorescent organic electroluminescent elements.
- organic compounds with TADF have low efficiency and lifespan. In general, the performance improvement is limited, which makes it difficult to improve the luminous efficiency and service life of organic electroluminescent elements using organic compounds containing TADF.
