[0003] One or more aspects of embodiments of the present disclosure relate to an amine-containing compound, a light-emitting device including the same, an electronic device including the light-emitting device, and electronic equipment including the light-emitting device. Background Art

[0004] Compared with inorganic light-emitting devices, organic light-emitting devices may have a wider viewing angle, a higher contrast ratio, and a shorter response time. The organic light-emitting device may include a first electrode, a hole transport region, an emission layer, an electron transport region, and a second electrode arranged in the order described below. Holes injected from the first electrode may move toward the emission layer through the hole transport region. Electrons injected from the second electrode may move toward the emission layer through the electron transport region. Carriers (such as holes and electrons) may recombine in the emission layer, for example, to generate excitons. These excitons may transition (for example, relax) from an excited state to a ground state to generate light. Summary of the invention

[0040] The embodiment in the accompanying drawings will now be explained in more detail with reference to its examples, wherein the same reference numerals throughout the specification refer to the same elements, and their repeated description may not be provided. In this regard, the present embodiment may have different forms and should not be interpreted as being limited to the description stated herein. Accordingly, the embodiment is described only by reference to the accompanying drawings to explain the aspects of this description. As used herein, the term "and / or" includes any and all combinations of one or more related enumerated items. When expressions such as "at least one of ...", "one of ..." and "selected from ..." are before / after the list of elements, the entire list of modified elements is modified without modifying the single element of the list. For example, throughout this disclosure, the expression "at least one of a, b and c" indicates only a, only b, only c, both a and b (e.g., a and b at the same time), both a and c (e.g., a and c at the same time), both b and c (e.g., b and c at the same time), all a, b and c, or variations thereof.

[0041] Unless otherwise limited, all chemical names, technical terms and scientific terms and terms defined in general dictionaries should be interpreted as having a meaning consistent with the context of the relevant field, and should not be interpreted in an ideal or overly formal sense. It will be understood that although the terms first and / or second, etc. can be used to describe various elements in this article, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, without departing from the teaching of the present disclosure, the first element can be referred to as the second element. Similarly, the second element can be referred to as the first element.

[0042] As used herein, singular forms such as “a”, “an” and “the” are intended to include plural forms as well, unless the context clearly indicates otherwise.

[0043] It will be further understood that when used in this specification, the terms “comprise,” “comprises,” “comprising,” “has,” “have,” “having,” “include,” “includes,” and / or “including” indicate the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0044] As used herein, the terms "use," "using," and "used" may be considered synonymous with the terms "utilize," "utilizing," and "utilized," respectively.

[0045] The term "may" will be understood to refer to "one or more embodiments of the present disclosure," some of which include the described elements, and some of which exclude the elements and / or include optional elements. Similarly, optional language (such as "or") refers to "one or more embodiments of the present disclosure" that each include the corresponding listed items.

[0046] It will be understood that when an element is referred to as being "on," "connected to," or "coupled to" another element, it may be directly on, directly connected to, or directly coupled to the other element, or one or more intervening elements may also be present. When an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements.

[0047] For ease of description, spatially relative terms such as "below," "below," "below," "above," "on," "bottom," and "top," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the accompanying drawings. It will be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, elements described as being "below" or "beneath" other elements or features will be oriented as being "above" or "on" the other elements or features. Thus, the term "below" may encompass both orientations above and below. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.

[0048] In the present context, "consisting essentially of" means that any additional components will not substantially affect the chemical, physical, optical or electrical properties of the target moiety.

[0049] In the present disclosure, "does not include (or does not contain) one or any 'component'", "excludes (or removes) one or any 'component'" and / or "no 'component'" etc. means that the "component" is not added, selected or used as a component in the element / composition, but due to other impurities and / or external factors, the "component" may still be included in an appropriate amount.

[0050] Furthermore, in this specification, the phrase “on a plane” or “plan view” means observing a target portion from the top, and the phrase “in a cross section” means observing a cross section formed by vertically cutting the target portion from the side.

Because the amine-containing compound represented by Formula 1 includes such a tricyclic group, a polaron (as used herein, the term "polaron" is a quasi-particle that may be included in the interaction between electrons and atoms in a solid material) may be stabilized, which leads to a long life of the light-emitting device, and the charge jump rate increases, thereby improving the charge mobility. Moreover, by introducing a substituent (e.g., substantially) into a naphthyl group, the color coordinates may be improved to emit dark blue light, and the structural stability of the amine-containing compound represented by Formula 1 may be ensured. Accordingly, the amine-containing compound represented by Formula 1 may have relatively high electrical stability, high charge transport capability, and high glass transition temperature.

[0156] And, by changing Ar 2 ,Ar 31 and Ar 32 The value of the highest occupied molecular orbital (HOMO) energy level can also be appropriately adjusted or changed, such as the substitution position of the anode, etc. Accordingly, the hole injection barrier from the anode to the hole transport layer can be appropriately adjusted or changed, and a suitable or appropriate energy level value can be maintained between the hole transport layer and the emission layer to increase the exciton generation efficiency inside the emission layer.

[0157] Therefore, the amine-containing compound represented by Formula 1 may have excellent or appropriate hole transport characteristics, and a light-emitting device including the amine-containing compound represented by Formula 1 may have a relatively low driving voltage, high luminous efficiency, and a long lifespan.

[0342] 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 at a non-substantially uniform concentration.

[0343] 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 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.

[0344] The shell of the quantum dot may act as a protective layer to prevent chemical denaturation of the core to maintain semiconductor properties and / or as a charging layer to impart electrophoretic properties to the quantum dot. The shell may be a single layer or multiple layers. The interface between the core and the shell may have a concentration gradient in which the concentration of the element present in the shell decreases toward the center of the core.

[0346] The full width at half maximum (FWHM) of the emission wavelength spectrum of the quantum dots can be about 45 nm or less, for example, about 40 nm or less, or for example, about 30 nm or less, and within these ranges, color purity or color reproducibility can be increased. In one or more embodiments, because the light emitted by the quantum dots is emitted in all directions, the wide viewing angle can be improved.

[0347] In one or more embodiments, the quantum dots may be in the form of (or provided as) spherical nanoparticles, pyramidal nanoparticles, multi-armed nanoparticles, cubic nanoparticles, nanotubes, nanowires, nanofibers, or nanoplates.

[0348] Because the band gap 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 emission layer. Accordingly, by utilizing 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 emit red light, green light, and / or blue light. In one or more embodiments, the size of the quantum dots can be configured to emit white light through a combination of one or more appropriate colors of light.
