Abstract
The invention provides an organic boron fused ring compound, a preparation method and application thereof. The organic condensed-cyclic compound can be used in an organic electroluminescent device, on one hand, the relaxation degree of an excited state structure can be reduced by utilizing the rigid framework structure of the condensed-cyclic compound, so that the narrower half-peak width is realized; on the other hand, carbazole units are bonded to the rigid framework of the fused ring compound through two modes of carbon-nitrogen bond and carbon-carbon bond to form a symmetrical structure or an asymmetrical structure, and hole traps are formed between the main body material and the fluorescent material by reducing HOMO energy level, so that the luminous efficiency and stability of the device are improved. Meanwhile, the steric hindrance of carbazole moieties increases the dihedral angle with the planar molecular skeleton to inhibit self aggregation and promote solubility. The maximum external quantum efficiency of the device is 23.9-31.4% through test, and the device has a narrow electroluminescent spectrum, and the half-peak width is smaller than 20nm.
Description
Technical Field
The invention belongs to the technical field of organic light-emitting devices, and particularly relates to an organic boron fused ring compound, a preparation method and application thereof.
Background
Organic Light Emitting Devices (OLEDs) have the characteristics of rich color, thin thickness, wide viewing angle, rapid response, and the like, and can be manufactured into flexible devices, which are considered to be the next generation flat panel display and solid lighting technologies that have the most promising development. In general, an OLED is composed of an ITO anode, a hole injection layer (TIL), a Hole Transport Layer (HTL), an Emission Layer (EL), a Hole Blocking Layer (HBL), an Electron Transport Layer (ETL), an Electron Injection Layer (EIL), and a cathode, and 1 to 2 organic layers may be omitted as needed, and excitons are formed by combining holes injected from the anode and the cathode on an organic thin film with electrons, and when the excitons return to a stable ground state from an excited state, energy is released in a light-emitting form to emit light. Thermally activated delayed fluorescence (thermally activated delayed fluorescence, TADF) materials are new generation organic luminescent materials following traditional fluorescent and phosphorescent materials, which generally have a small singlet-triplet energy level difference (Δe) ST ) The triplet state excitons are transferred to the singlet state excitons to emit fluorescence by utilizing a thermally activated reverse intersystem crossing (RISC) process, so that the full utilization of the singlet state excitons and the triplet state excitons is realized, and the internal quantum efficiency of 100% is realized. In 2019, the international telecommunications union radio communications sector (ITU-R) promulgates bt.2020 standards for new generation ultra-high definition video production and display systems, employing a wider color gamut space to meet richer color displays. To meet this requirement, researchers have found that improving the color purity of luminescent materials is one of the effective ways to achieve a wider color gamut display.
The multi-resonance heat-activated delayed fluorescence (MR-TADF) material has the characteristics of high efficiency and high color purity, and is suitable for the ultra-high definition display of a new generation of wide color gamut.
