Description

Technical Field

[0001] This invention relates to the field of organic electroluminescent materials technology, specifically to a compound containing condensed furan and its organic electroluminescent device. Background Technology

[0002] Since achieving a key breakthrough in the 1980s, OLED technology has moved from the laboratory to large-scale commercial applications, becoming a core technology for next-generation display devices. Compared to traditional liquid crystal display technology, OLED devices are structurally stable, ultra-thin, and lightweight, and inherently possess flexible, foldable, and bendable characteristics, bringing revolutionary innovation to the form factor of end products. In addition, OLED also has advantages such as wide viewing angle, high color gamut, and the ability to be fabricated using low-temperature solution processes, establishing its leading position in the high-end display market and future flexible electronics.

[0003] Organic light-emitting diodes (OLEDs) are solid-state electroluminescent devices based on organic semiconductor materials. The essence of their light emission is the direct conversion of electrical energy into light energy. The light-emitting process is as follows: When a voltage is applied between the cathode and anode of the device, free electrons are generated on the cathode side, and holes are generated on the anode side. Electrons and holes are injected from the cathode and anode respectively, and migrate towards each other under the influence of an applied electric field. Electrons pass through the electron injection layer and transport layer, and holes pass through the hole injection layer and transport layer, eventually meeting and recombinating in the light-emitting layer to form excitons. The excited excitons return to the ground state through radiative relaxation, releasing their excess energy as photons, thus producing visible light. OLED devices are typically constructed using a finely stacked multilayer functional structure. A common device structure includes: a substrate, anode, hole injection layer, hole transport layer, light-emitting layer (usually composed of a host material and dopants), electron transport layer, electron injection layer, cathode, and an outermost capping layer. The material properties of each layer and the energy level matching between layers play a crucial role in the final performance of the device.

[0004] Among these, the capping layer (CPL) and the emissive layer (EML) are two crucial core materials, whose performance directly determines the device's efficiency and lifetime. The capping layer utilizes optical interference effects to modulate light output; the emissive layer's host material carries energy and efficiently transfers it to the doped luminescent guest. Its triplet energy level must be significantly higher than that of the dopant to effectively limit exciton energy backflow and prevent energy quenching. Its highest occupied molecular orbital (HOMO) / lowest unoccupied molecular orbital (LUMO) energy levels must match those of the adjacent transport layer to reduce the injection barrier. However, currently, traditional capping layer materials have light extraction efficiencies of only around 20%, insufficient refractive index, or poor stability under high-energy light illumination; and commonly used host materials suffer from insufficient energy levels. Therefore, developing novel capping layer and host materials has become a key focus of research in the industry. Summary of the Invention
