[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application with application number CN2023112871093 filed on October 7, 2023. The full text of the above-mentioned Chinese patent application is hereby cited as part of this application. Technical Field

[0003] The present application relates to the field of organic electroluminescence, and in particular to an organic compound, an electronic component and an electronic device. Background Art

[0004] Organic electroluminescence refers to the phenomenon of converting electrical energy into light energy using organic substances. Organic electroluminescent display devices are a type of self-luminous display device that generates excitons through the transfer and recombination of carriers between various functional layers, and relies on high-quantum-efficiency organic compounds or metal complexes to emit light. Organic electroluminescent devices (OLEDs, i.e. organic light-emitting diodes) are a type of self-luminous electronic components with the characteristics of high contrast, wide viewing angle, fast response speed, and excellent color expression. They can also be prepared on flexible substrates into rollable or bendable flexible display products. Therefore, in recent years, OLED displays have been widely used in consumer electronics such as mobile phones, tablets, and wall-mounted TVs, as well as in the field of vehicle-mounted displays.

[0005] The structure of an organic electroluminescent element typically includes an anode, a cathode, and an organic functional layer between them. To improve the efficiency and lifespan of an organic electroluminescent element, the organic layer has a multilayer structure, with each layer containing different organic substances. Specifically, it may include a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer, and an electron injection layer. In such an organic electroluminescent element, when a voltage is applied between the two electrodes, holes are injected from the anode into the organic layer, and electrons are injected from the cathode into the organic layer. When the injected holes and electrons meet, excitons are formed, which emit light when they transition back to the ground state.

[0006] Therefore, to achieve efficient organic electroluminescent devices, in addition to developing high-performance materials for the light-emitting layer, it is also crucial to develop corresponding hole-transporting materials, such as those for the luminescence-modulating layer. Therefore, designing new, higher-performing materials to enhance device performance has long been a pressing challenge for those skilled in the art.

[0007] Summary of the Invention

[0008] The purpose of the present application is to provide an organic compound, an electronic component and an electronic device. Using the organic compound in an organic electroluminescent device can improve the performance of the device.

[0009] The first aspect of the present application provides an organic compound having a structure shown in Formula 1:

[0010] wherein one of R1 and R2 is selected from the other is selected from H or D;

[0011] n is selected from 1, 2, 3 or 4;

[0012] L is selected from a single bond, a substituted or unsubstituted phenylene group, a substituted or unsubstituted naphthylene group, or a substituted or unsubstituted biphenylene group;

[0013] Ar is selected from substituted or unsubstituted phenyl, substituted or unsubstituted naphthyl, substituted or unsubstituted phenanthrenyl, substituted or unsubstituted biphenyl, substituted or unsubstituted terphenyl, substituted or unsubstituted dibenzofuranyl, substituted or unsubstituted dibenzothiophenyl, substituted or unsubstituted carbazolyl;

[0014] The substituents in L and Ar are the same or different and are independently selected from deuterium, fluorine, cyano, an alkyl group having 1 to 5 carbon atoms, a trideuterated methyl group or a phenyl group;

[0015] L1, L2 and L3 are the same or different and are each independently selected from a single bond, a substituted or unsubstituted arylene group having 6 to 30 carbon atoms, or a substituted or unsubstituted heteroarylene group having 3 to 30 carbon atoms;

[0016] Ar1 and Ar2 are the same or different and are each independently selected from a substituted or unsubstituted aryl group having 6 to 40 carbon atoms, or a substituted or unsubstituted heteroaryl group having 3 to 40 carbon atoms;

[0017] The substituents in L1, L2, L3, Ar1 and Ar2 are the same or different and are each independently selected from deuterium, a halogen group, a cyano group, an alkyl group having 1 to 10 carbon atoms, a haloalkyl group having 1 to 10 carbon atoms, a deuterated alkyl group having 1 to 10 carbon atoms, a trialkylsilyl group having 3 to 12 carbon atoms, an aryl group having 6 to 20 carbon atoms or a heteroaryl group having 3 to 20 carbon atoms.

[0018] The second aspect of the present application provides an electronic component, comprising an anode and a cathode arranged opposite to each other, and a functional layer arranged between the anode and the cathode; the functional layer comprises the organic compound described in the first aspect.

[0019] A third aspect of the present application provides an electronic device comprising the electronic component described in the second aspect.

[0020] The organic compound of the present application has a 3-position or 4-position of the cycloalkane spirofluorene structure. Introducing a specific set of aryl / heteroaryl groups At the same time, an aromatic amine group is connected to the benzene ring of the fluorene group, and the entire compound presents a non-linear structural connection mode. This "cycloalkyl spirofluorene + aromatic amine" type compound also has a higher conjugated area and a higher degree of spatial distortion. The organic compound of the present application, on the one hand, has a reasonable glass transition temperature (Tg) range. When it is applied to the preparation of OLED devices for evaporation, it has a better evaporation morphology, which prolongs the service life of the device; on the other hand, the aromatic / heteroaromatic and aromatic amine groups at the 3rd or 4th positions of the spirofluorene plane form a complete π-π conjugated plane with the fluorene ring of the spirofluorene structure. This structural feature effectively increases the conjugated area of ​​the molecule, thereby increasing the molecular mobility and avoiding the formation of hole transport traps. Applying it to the luminescence adjustment layer of OLED devices can effectively improve the luminous efficiency of the device. Compared with existing hole transport materials, the organic compound of the present application can avoid the problems of high evaporation temperature and easy crystallization in traditional materials due to the overly stretched molecular structure. When the organic compound of the present application is applied as a luminescence adjustment layer to an OLED device, it can not only improve the molecular mobility of the material, but also exhibit excellent thermal stability, effectively improving the problems of traditional materials such as easy crystallization, poor film uniformity, and short service life during repeated charge and discharge use of the device.
