Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0145425 filed in the Korean Intellectual Property Office on October 27, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Embodiments relate to an organometallic compound, an organic light-emitting device including the same, and electronic equipment and electronic devices including the organic light-emitting device. Background Art

[0004] Among light-emitting devices, an organic light-emitting device is a self-emitting device having wide viewing angles, high contrast, short response time, and excellent characteristics in terms of brightness, driving voltage, and response speed compared to devices in the related art.

[0005] In an example, an organic light-emitting device may have a structure in which a first electrode is arranged on a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode are sequentially formed 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. Excitons may transition from an excited state to a ground state, thereby generating light.

[0006] It should be understood that this background section is intended, in part, to provide a useful background for understanding the technology. However, this background section may also include ideas, concepts, or cognitions that were not part of the knowledge or understanding of a person skilled in the relevant art before the corresponding effective filing date of the subject matter disclosed herein. Summary of the invention

[0007] Embodiments provide a novel organometallic compound and an organic light-emitting device having low driving voltage and high light-emitting efficiency by including the novel organometallic compound. Embodiments include electronic devices and electronic equipment including the organic light-emitting device.

[0077] The present disclosure will now be described more fully below with reference to the attached drawings in which embodiments are shown. However, the present disclosure may be embodied in different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete and will fully convey the scope of the present disclosure to those skilled in the art.

[0078] In the drawings, the size (eg, thickness), ratio, and dimensions of elements may be exaggerated for ease of description and for clarity. The same reference numerals and the same reference characters refer to the same elements throughout.

[0079] In the specification, it will be understood that when an element (or region, layer, portion, etc.) is referred to as being “on”, “connected to” or “coupled to” another element (or region, layer, portion, etc.), it may be directly on, connected to or coupled to the other element (or region, layer, portion, etc.), or one or more intervening elements (or regions, layers, portions, etc.) may be present therebetween. In a similar sense, when an element (or region, layer, portion, etc.) is described as “covering” another element (or region, layer, portion, etc.), it may directly cover the other element (or region, layer, portion, etc.), or one or more intervening elements (or regions, layers, portions, etc.) may be present therebetween.

[0080] In the specification, when an element is "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements. For example, "directly on" may mean that two layers or two elements are disposed without another element (such as an adhesive element) between them.

[0081] In the specification, expressions used in the singular such as "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0082] In the specification, the term "and / or" includes any and all combinations of one or more related listed items. For example, "A and / or B" can be understood to mean "A, B, or A and B". The terms "and" and "or" can be used in a connecting sense or a separating sense and can be understood to be equivalent to "and / or".

[0083] In the specification and claims, for the purposes of its meaning and interpretation, the term "at least one of" is intended to include the meaning of "at least one selected from the group consisting of." For example, "at least one of A, B, and C" may be understood to mean only A, only B, only C, or any combination of two or more of A, B, and C, such as ABC, ACC, BC, or CC. When following a list of elements, the term "at least one of" modifies the entire list of elements and does not modify the individual elements of the list.

[0084] It will be understood that although the terms first, second, etc. may 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 teachings of the present disclosure, the first element may be referred to as the second element. Similarly, without departing from the scope of the present disclosure, the second element may be referred to as the first element.

[0085] For ease of description, spatially relative terms such as "below," "under," "below," "above," or "over" may be used herein to describe the relationship between one element or component and another element or component as illustrated in the accompanying drawings. It will be understood that the 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, in the case where the device illustrated in the accompanying drawings is turned over, a device that is "below" or "below" another device may be placed "over" the other device. Accordingly, the illustrative term "below" may include both a below position and an above position. The device may also be oriented in other directions, and thus the spatially relative terms may be interpreted differently depending on the orientation.

[0086] As used herein, the terms "about" or "approximately" include the stated value and mean within an acceptable range of deviation from the stated value as determined by one of ordinary skill in the art taking into account the measurement in question and errors associated with the measurement of the stated quantity (i.e., limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated value, or within ±20%, ±10%, or ±5% of the stated value.

[0087] It should be understood that the terms “comprise,” “comprising,” “include,” “including,” “have,” “having,” “contains,” and “containing” and the like are intended to indicate the presence of specified features, integers, steps, operations, elements, components, or any combination thereof in the present disclosure, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or any combination thereof.

[0088] Unless otherwise defined or implied herein, all terms (including technical terms and scientific terms) used have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and should not be interpreted in an ideal or overly formal sense unless clearly defined in the specification.

[0192] In an embodiment, the organometallic compound represented by Formula 1 may be electrically neutral.

[0196]

[0197]

[0198]

[0199]

[0200]

[0201] The organometallic compound represented by Formula 1 has a structure in which a long alkyl chain is introduced into a carbazole group, and thus may have a reduced sublimation temperature and improved heat resistance stability. The intensity of the secondary emission may be reduced by the long alkyl chain, so that the color purity may be improved, which may contribute to increasing the luminous efficiency and improving the lifespan. In the emission spectrum of the organometallic compound, it is ideal that only the first peak exists, but in the case of some compounds, the second peak exists. When the second peak exists, the FWHM increases, and the color purity decreases. The intensity of the secondary emission means the emission of the second peak.

[0202] Therefore, the organic light-emitting device including the organometallic compound represented by Formula 1 can have low driving voltage and high luminous efficiency. For example, in the case of including the organometallic compound represented by Formula 1 as a dopant in the emission layer, the organic light-emitting device including the organometallic compound represented by Formula 1 can exhibit low driving voltage, high luminous efficiency, high color conversion efficiency and long life.
