[0002] This application claims priority and benefit to Korean Patent Application No. 10-2024-0063415, filed on May 14, 2024, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] One or more embodiments of this disclosure relate to compounds, light-emitting devices, and electronic devices including the same. Background Technology

[0004] Among light-emitting devices, self-emitting devices (e.g., organic light-emitting devices) possess relatively wide viewing angles, high contrast, short response times, and superior or suitable characteristics in terms of brightness, driving voltage, and response speed. In other words, self-emitting devices (such as organic light-emitting devices) stand out among light-emitting devices due to their wide viewing angles, high contrast, fast response times, and superior characteristics in terms of brightness, driving voltage, and response speed.

[0005] In a light-emitting device, a first electrode is disposed on a substrate, and a hole transport region, an emitter layer, an electron transport region, and a second electrode are sequentially disposed on the first electrode in the order described. Holes supplied from the first electrode move toward the emitter layer through the hole transport region, and electrons supplied from the second electrode move toward the emitter layer through the electron transport region. Charge carriers (such as holes and electrons) recombine in the emitter layer to generate excitons. These excitons can transition from excited states and decay to the ground state, thereby generating light (e.g., to display an image). Summary of the Invention

[0061] Q1to Q3, Q 11 to Q 13 , Q 21 to Q 23 and Q 31 to Q 33 may each independently be: hydrogen; deuterium; -F; -Cl; -Br; -I; hydroxyl; cyano; nitro; C1-C 60 alkyl; C2-C 60 alkenyl; C2-C 60 alkynyl; C1-C 60 alkoxy; or each unsubstituted or substituted with deuterium, -F, cyano, C1-C 60 alkyl, C1-C 60 alkoxy, phenyl, biphenyl, or any combination thereof; C3-C 60 carbocyclyl, C1-C 60 heterocyclyl, C7-C 60 aralkyl, or C2-C 60 heteroaralkyl.

[0062] A compound represented by Formula 1 can have electrical stability as well as excellent or appropriate charge transportability by including a triazine moiety directly substituted with an alkyl group or a cycloalkyl group. A light-emitting device including the compound represented by Formula 1 can have excellent or appropriate driving voltage, luminous efficiency, and lifespan.

[0063] According to one or more embodiments, the first electrode can be an anode, the second electrode can be a cathode, and the interlayer can further include a hole transport zone between the first electrode and the emission layer, and including a hole injection layer, a hole transport layer, an electron blocking layer, an emission auxiliary layer, or any combination thereof.

[0064] According to one or more embodiments, the first electrode can be an anode, the second electrode can be a cathode, and the interlayer can further include an electron transport zone between the second electrode and the emissive layer, and including a hole blocking layer, an electron transport layer, an electron injection layer, or any combination thereof.

[0065] According to one or more embodiments, the electron transport zone can include a compound represented by Formula 1. For example, in one or more embodiments, the hole blocking layer can include a compound represented by Formula 1. For example, in one or more embodiments, the electron transport layer can include a compound represented by Formula 1. For example, in one or more embodiments, the electron injection layer can include a compound represented by Formula 1.

[0066] According to one or more embodiments, the emissive layer can include a first host, a second host, a first dopant, and a second dopant, the first dopant being a compound including a metal and a ligand, the ligand including an imidazole moiety, and the second dopant can be a compound including boron.

[0067] According to one or more embodiments, the first host can be a hole transport host.

[0068] According to one or more embodiments, the second host can be an electron transport host.

[0069] The hole transport host can be a compound having strong hole properties. The expression "compound having strong hole properties" refers to a compound that is easy to accept a hole and transport the hole with an appropriate carrier mobility, and such properties can be obtained by including a hole accepting moiety (also referred to as a hole transport (HT) moiety).

[0070] Such a hole accepting moiety can include, for example, a π-electron rich heteroaromatic compound (e.g., a carbazole derivative or an indole derivative) or an aromatic amine compound.

[0071] The electron transport host can be a compound having strong electron properties. The expression "compound having strong electron properties" refers to a compound that is easy to accept an electron and transport the electron with an appropriate carrier mobility, and such properties can be obtained by including an electron accepting moiety (also referred to as an electron transport (ET) moiety).

[0072] Such an electron accepting moiety can include, for example, a π-electron deficient heteroaromatic compound. For example, the electron accepting moiety can include a nitrogen-containing heteroaromatic compound.

[0073] When a compound includes only an HT moiety or only an ET moiety, it is clear whether the properties of the compound are HT properties or ET properties.

[0074] In one or more embodiments, a compound can include (e.g., simultaneously) both an HT moiety and an ET moiety. In this case, a simple comparison between the total number of HT moieties and the total number of ET moieties in the compound can be a criterion, but can not be an absolute criterion, to predict whether the compound is an HT compound or an ET compound. One of the reasons why such a simple comparison can not be an absolute criterion is that one HT moiety and one ET moiety do not have exactly the same ability to attract holes and electrons, respectively.

[0075] Therefore, a relatively reliable method to determine whether a compound having a particular structure is an HT compound or an ET compound is to implement the compound directly in a device.

[0076] In one or more embodiments, the weight ratio of the first host to the second host can be in a range from about 9: 1 to about 1 :9. For example, in one or more embodiments, the weight ratio of the first host to the second host can be in a range from about 6:4 to about 4:6. When the weight ratio of the first host to the second host is in the above range, the balance of injected charges can be suitable or appropriate.

[0077] According to one or more embodiments, the metal of the first dopant can include a transition metal.

[0078] For example, in one or more embodiments, the first dopant can include a compound represented by Formula 401:

[0079] Formula 401

[0080] M(L 401 ) xc1 (L 402 ) xc2

[0081] Formula 402

[0082]

[0083] wherein, in Formula 401 and Formula 402,

[0084] M can be titanium (Ti), cobalt (Co), copper (Cu), zinc (Zn), zirconium (Zr), ruthenium (Ru), rhodium (Rh), palladium (Pd), rhenium (Re), platinum (Pt), gold (Au), osmium (Os), iridium (Ir), or rhenium (Re),

[0085] L 401 may be a ligand represented by Formula 402, and xc1may be 1, 2, or 3, wherein if (e.g., when) xc1is 2 or more, two or more L 401 may be the same as or different from each other,

[0086] L 402It can be an organic ligand, and xc2 can be 0, 1, 2, 3, or 4, and if (for example, when) xc2 is 2 or greater, two or more L 402 They can be the same or different from each other.

[0087] X 401 and X 402 They can be nitrogen or carbon independently.

[0092] In one or more embodiments, selected from R 401 and R 402 Adjacent groups in the group can be linked to form a ring (i.e., optionally, in one or more embodiments, selected from R...). 401 and R 402 Adjacent groups in the group can connect to form a ring.

[0311] According to one or more embodiments, the amount of the second dopant can be in the range of about 1.0 wt% to about 7.0 wt% (based on 100 parts by weight of the total host). When the amount of the second dopant is in the above range, the light emitting device can have excellent or proper luminous efficiency and lifespan.

[0317] Quantum dot

[0318] According to one or more embodiments of the disclosure, an electronic device can include a quantum dot. For example, in one or more embodiments, the electronic device can include a color filter, and the color filter can include a quantum dot.

[0319] The term "quantum dot" as used herein refers to a crystal of a semiconductor compound, and can include any material capable of emitting light of one or more appropriate emission wavelengths according to the size of the crystal. The quantum dot can also emit light of one or more appropriate emission wavelengths by adjusting the element ratio in the quantum dot compound.

[0320] The diameter of the quantum dot can be in the range of, for example, about 1 nanometer (nm) to about 10 nm. In the disclosure, when the quantum dot, the plurality of quantum dots, or the quantum dot particle is spherical, the "diameter" indicates the particle diameter or the average particle diameter, and when the particle is non-spherical, the "diameter" indicates the length of the long axis or the average length of the long axis. The diameter of the particle can be measured using a scanning electron microscope or a particle size analyzer. As the particle size analyzer, for example, a HORIBA, LA-950 laser particle size analyzer can be used. When the size of the particle is measured using the particle size analyzer, the average particle diameter is referred to as D 50 . D 50 indicates the average diameter of the cumulative volume corresponding to 50% of the particles in the particle size distribution (e.g., cumulative distribution), and indicates the particle size value corresponding to 50% of the particles from the smallest particle when the total number of particles is 100% in the distribution curve accumulated in order from the smallest particle size to the largest particle size.

[0322] A wet-chemical process is a method including mixing a precursor material of a quantum dot with an organic solvent and then growing a quantum dot particle crystal. When the quantum dot particle crystal grows, the organic solvent naturally serves as a dispersant coordinated on the surface of the quantum dot particle crystal, and controls the growth of the quantum dot particle crystal, so that the growth of the quantum dot particle crystal can be controlled or selected by a process that is less costly and easier than a gas phase deposition method such as metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE).

[0323] The quantum dot can include: a Group II-VI semiconductor compound; a Group III-V semiconductor compound; a Group III-VI semiconductor compound; a Group I-III-VI semiconductor compound; a Group IV-VI semiconductor compound; a Group IV element or compound; or any combination thereof.

[0330] Each element included in the multi-element compound, such as binary compounds, ternary compounds, and quaternary compounds, can exist in the particle in a substantially uniform concentration or a non-uniform concentration.

[0331] In one or more embodiments, the quantum dot can have a single structure in which the concentration of each element in the quantum dot is substantially uniform, or a core-shell double structure. For example, the material included in the core and the material included in the shell can be different from each other.

[0332] The shell of the quantum dot can act as a protective layer that prevents chemical denaturation of the core to maintain the semiconductor property, and / or as a charging layer that imparts 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 center of the core.

[0333] Examples of the shell of the quantum dot can include an oxide of a metal, a metalloid, or a non-metal, a semiconductor compound, or any combination thereof. Non-limiting examples of the oxide of a metal, a metalloid, or a non-metal can include: a binary compound, such as SiO2, Al2O3, TiO2, ZnO, MnO, Mn2O3, Mn3O4, CuO, FeO, Fe2O3, Fe3O4, CoO, Co3O4, and / or NiO, etc.; a ternary compound, such as MgAl2O4, CoFe2O4, NiFe2O4, and / or CoMn2O4, etc.; or any combination thereof.

[0334] The full width at half maximum (FWHM) of the emission spectrum of the quantum dot can be about 45 nm or less, for example, about 40 nm or less, for example, about 30 nm or less, and within these ranges, the color purity or color reproducibility of the quantum dot can be increased.

[0335] In addition, the quantum dots can be in the form of spherical nanoparticles, pyramidal nanoparticles, multi-armed nanoparticles, cubic nanoparticles, nanotubes, nanowires, nanofibers, or nanoplates.

[0336] Because the energy band gap of the quantum dots can be adjusted by controlling the size of the quantum dots, light having one or more appropriate wavelength bands can be obtained from the quantum dot emissive layer. Accordingly, by using quantum dots of different sizes, a light emitting device that emits light of one or more appropriate wavelength bands can be implemented. In one or more embodiments, the size of the quantum dots can be selected to ensure that the quantum dots emit red light, green light, and / or blue light.
