Description

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0087895 filed in the Korean Intellectual Property Office on July 6, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0002] One or more embodiments of the present disclosure relate to a light emitting device including an amine-containing compound, an electronic device and electronic equipment including the light emitting device, and the amine-containing compound. Background Art

[0003] Among light emitting devices, self-emitting devices (eg, organic light emitting devices) have relatively wide viewing angles, high contrast, short response times, and excellent or suitable characteristics in terms of brightness, driving voltage, and response speed.

[0004] In the light-emitting device, a first electrode is disposed on a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode are sequentially disposed on the first electrode. Holes provided from the first electrode move toward the emission layer through the hole transport region, and electrons provided from the second electrode move toward the emission layer through the electron transport region. Carriers such as holes and electrons recombine in the emission layer to generate excitons. These excitons transition from an excited state and decay to a ground state, thereby generating light. Summary of the invention

[0121] The amine-containing compound represented by Formula 1 includes a p-terphenyl group substituted by two phenyl groups through a linker connecting multiple amines, and the two phenyl groups substituted on the p-terphenyl group do not include substituents such as aryl and / or heteroaryl groups. Therefore, the amine-containing compound represented by Formula 1 can exhibit excellent or suitable hole transport capabilities while maintaining a relatively small molecular weight. Therefore, compared with a comparative compound including a p-terphenyl group substituted by two phenyl groups including a substituent group (such as aryl and / or heteroaryl groups, etc.) with a large molecular weight, the amine-containing compound represented by Formula 1 can have a low sublimation temperature and excellent or suitable thermal stability. In one or more embodiments, compared with a comparative compound including a p-terphenyl group substituted by two phenyl groups including a substituent group (such as aryl and / or heteroaryl groups, etc.) with a large molecular weight, the amine-containing compound represented by Formula 1 causes relatively little stacking. Therefore, assuming the same molecular weight, the increase in sublimation temperature can be relatively small compared to the increase in molecular weight. Due to this low sublimation temperature and excellent or suitable thermal stability, the amine-containing compound represented by Formula 1 can exhibit enhanced luminous efficiency during the deposition process. For example, the thermal stability of amine-containing compounds can be determined by the first derivative peak temperature (Tp) in vacuum thermogravimetric analysis.

[0385] Delayed fluorescence material

[0386] In one or more embodiments, the emissive layer may include a delayed fluorescent material.

[0387] In the present disclosure, the delayed fluorescent material may be selected from compounds capable of emitting delayed fluorescence based on a delayed fluorescence emission mechanism.

[0388] The delayed fluorescent material included in the emission layer may act as a host or a dopant according to the types (kinds) of other materials included in the emission layer.

[0389] In one or more embodiments, the difference between the triplet energy level (eV) of the delayed fluorescent material and the singlet energy level (eV) of the delayed fluorescent material may be in the range of about 0 eV to about 0.5 eV. When the difference between the triplet energy level (eV) of the delayed fluorescent material and the singlet energy level (eV) of the delayed fluorescent material is in the above range, the up-conversion of the delayed fluorescent material from the triplet state to the singlet state may effectively occur, and thus, the light emitting device 10 may have improved luminous efficiency.

[0392]

[0393]

[0394] quantum dots

[0395] In one or more embodiments, the emissive layer may include quantum dots.

[0396] The term "quantum dot" as utilized herein refers to a crystal of a semiconductor compound, and may include any material capable of emitting light at one or more suitable emission wavelengths depending on the size of the crystal.

[0397] The diameter of the quantum dot can be, for example, in the range of about 1 nm to about 10 nm. In the present disclosure, when the particle is spherical, "diameter" means the particle size or the average particle size, and when the particle is non-spherical, "diameter" means the major axis length or the average major axis length. The diameter of the particle can be measured using a scanning electron microscope or a particle size analyzer. As a particle size analyzer, for example, HORIBA, LA-950 laser particle size analyzer can be used. When the size of the particle is measured using a particle size analyzer, the average particle size is referred to as D50. D50 refers to the average diameter of the particles whose cumulative volume corresponds to 50% by volume in a particle size distribution (e.g., cumulative distribution), and refers to the particle size value corresponding to 50% of the smallest particles accumulated in the distribution curve in the order of the smallest particle size to the largest particle size when the total number of particles is 100%.

[0398] Quantum dots can be synthesized by wet chemical processes, metal organic chemical vapor deposition processes, molecular beam epitaxy processes, or any similar process.

[0399] The wet chemical process is a method in which the precursor material of the quantum dot is mixed with an organic solvent and then the quantum dot particle crystal is grown. When the quantum dot particle crystal grows, the organic solvent can naturally act as a dispersant coordinated on the surface of the quantum dot particle crystal and can control the growth of the quantum dot particle crystal. Therefore, the wet chemical process can be performed more easily than a vapor deposition process (such as metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE)), and the growth of the quantum dot particle crystal can be controlled or selected by a low-cost process.

[0400] Quantum dots may include: Group II-VI semiconductor compounds; Group III-V semiconductor compounds; Group III-VI semiconductor compounds; Group I-III-VI semiconductor compounds; Group IV-VI semiconductor compounds; Group IV elements or compounds; or any combination thereof.

[0404] Non-limiting examples of Group I-III-VI semiconductor compounds may include: ternary compounds such as AgInS, AgInS 2 、CuInS、CuInS 2 、CuGaO 2 、AgGaO 2 and / or AgAlO 2 etc.; or any combination thereof.

[0406] The Group IV elements or compounds may include: single element materials, such as Si and / or Ge, etc.; binary compounds, such as SiC and / or SiGe, etc.; or any combination thereof.

[0407] Each element included in the multi-element compound such as the binary compound, the ternary compound, and the quaternary compound may be present in the particle at a substantially uniform concentration or a substantially non-uniform concentration.

[0408] In one or more embodiments, the quantum dot may have a single structure in which the concentration of each element in the quantum dot is substantially uniform, or may have a core-shell dual structure. For example, the material included in the core and the material included in the shell may be different from each other.

[0409] The shell of a quantum dot (e.g., a shell around the core of a quantum dot) can act as a protective layer to prevent chemical denaturation of the core to maintain semiconductor properties, and / or act as a charged layer to impart electrophoretic properties to the quantum dot. The shell can be a single layer or multiple layers. The interface between the core and the shell can have a concentration gradient in which the concentration of the element present in the shell decreases toward the core.

[0410] Non-limiting examples of the shell of the quantum dot may include oxides of metals, metalloids or non-metals, semiconductor compounds, or combinations thereof. Non-limiting examples of oxides of metals, metalloids or non-metals may include binary compounds such as SiO 2 、Al 2 O 3 、TiO2 、ZnO、MnO、Mn 2 O 3 , Mn 3 O 4 , CuO, FeO, Fe 2 O 3 , Fe 3 O 4 , CoO, Co 3 O 4 or NiO; ternary compounds such as MgAl 2 O 4 、CoFe 2 O 4 、NiFe 2 O 4 or CoMn 2 O 4 ; or any combination thereof. As described herein, examples of semiconductor compounds may include: II-VI semiconductor compounds; III-V semiconductor compounds; III-VI semiconductor compounds; I-III-VI semiconductor compounds; IV-VI semiconductor compounds; or any combination thereof. For example, semiconductor compounds suitable as shells may include CdS, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnSeS, ZnTeS, GaAs, GaP, GaSb, HgS, HgSe, HgTe, InAs, InP, InGaP, InSb, AlAs, AlP, AlSb, or any combination thereof.

[0411] The quantum dot may have a full width at half maximum (FWHM) of an emission spectrum of about 45 nm or less (e.g., about 40 nm or less, e.g., about 30 nm or less). When the FWHM of the emission spectrum of the quantum dot is within the above range, the color purity or color reproducibility of the quantum dot may be improved. In some embodiments, because the light emitted by the quantum dot is emitted in all directions, the wide viewing angle may be improved.

[0412] In some embodiments, quantum dots can be, for example, spherical nanoparticles, pyramidal nanoparticles, multi-armed nanoparticles, or cubic nanoparticles, nanotubes, nanowires, nanofibers, or nanoplates.

[0413] By adjusting the size of the quantum dots, the energy band gap of the quantum dots can be adjusted, and therefore, one or more suitable wavelengths of light can be obtained in the quantum dot emission layer. Therefore, by using quantum dots with different sizes, a light-emitting device that emits light of one or more suitable wavelengths can be realized. In one or more embodiments, the size of the quantum dots can be selected so that red light, green light and / or blue light can be emitted. In some embodiments, quantum dots with suitable sizes can be configured to emit white light by combining one or more suitable colors of light.
