Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2024-0019160 filed in the Korean Intellectual Property Office on February 7, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Embodiments relate to heterocyclic compounds, organic light-emitting devices including the heterocyclic compounds, and electronic devices and consumer products including the organic light-emitting devices. Background Art

[0004] Organic light-emitting devices are self-emissive devices that have wide viewing angles, high contrast, short response times, and superior characteristics in terms of brightness, driving voltage, and response speed compared to related art devices, and produce full-color images.

[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 may be 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. The excitons may transition from an excited state to a ground state, thereby generating light.

[0006] It is to 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 cognition that were not known or understood by those skilled in the relevant art before the corresponding effective filing date of the subject matter disclosed herein.

[0068] The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments are shown. However, the present disclosure can be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those skilled in the art.

[0069] In the drawings, the size, proportion, and dimensions (eg, thickness) of elements may be exaggerated for ease of description and for clarity. Like reference numerals and / or like reference characters refer to like elements throughout.

[0070] In the description, 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 can be directly on, directly connected to, or directly coupled to the other element (or region, layer, portion, etc.), or one or more intervening elements may be present therebetween. In a similar sense, when an element (or region, layer, portion, etc.) is described as “overlaying” another element (or region, layer, portion, etc.), it can directly cover the other element (or region, layer, portion, etc.), or one or more intervening elements may be present therebetween.

[0071] In the description, when an element is “directly on,” “directly connected to,” or “directly coupled to” another element, there are no intervening elements present. For example, “directly on” may mean that two layers or two elements are disposed without another element (such as an adhesive element) between them.

[0072] As used herein, 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.

[0073] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. For example, "A and / or B" may be understood to mean "A, B, or A and B." The terms "and" and "or" may be used in either a conjunctive or disjunctive sense and may be understood to be equivalent to "and / or."

[0074] In the specification and claims, the term "at least one of" is intended to include the meaning of "at least one selected from the group consisting of" for purposes of its meaning and interpretation. 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.

[0075] 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.

[0076] For ease of description, spatially relative terms such as "below," "beneath," "below," "above," or "upper" 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, if the device illustrated in the accompanying drawings is turned over, the device that is located "below" or "beneath" another device may be placed "above" the other device. Accordingly, the illustrative term "below" may include both a lower position and an upper position. The device may also be oriented in other directions, and thus the spatially relative terms may be interpreted differently depending on the orientation.

[0077] As used herein, the term "about" or "approximately" is inclusive of the stated value and means 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 (e.g., 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.

[0078] It should be understood that the terms “comprises,” “comprising,” “include,” “including,” “have,” “having,” “contains,” and “containing” are intended to indicate the presence of the recited features, integers, steps, operations, elements, components, or combinations 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 combinations thereof.

[0079] Unless otherwise defined or implied herein, all terms (including technical and scientific terms) used have the same meaning as 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.

[0285] In an embodiment, the heterocyclic compound represented by Formula 1 may be one of Compound 1 to Compound 182, but the embodiment is not limited thereto:

[0286]

[0287]

[0288]

[0289]

[0290]

[0291]

[0292]

[0293]

[0294]

[0295] The heterocyclic compound represented by Formula 1 may include a heterocyclic ring containing a boron atom and may have a condensed ring structure in which X1 is at a meta position relative to the carbon atom bonded to the boron atom. In Formula 1, when A1 is a group represented by Formula 2, Y 11 can be connected to an atom other than X2 in Formula 2, and when A2 is a group represented by Formula 2, Y 21 It may be connected to an atom other than X2 in Formula 2. Due to this structure, the heterocyclic compound represented by Formula 1 may have a narrow full width at half maximum, high color purity, and high luminous efficiency.

[0296] Although not limited to any particular theory, the heterocyclic compound represented by Formula 1 can exhibit a multiple resonance effect due to the sequential separation of the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO), improve the stability of the material by reducing intermolecular interactions due to steric effects, and inhibit Dexter energy transfer, thereby exhibiting high luminous efficiency characteristics when applied to a device.

[0297] Although not limited to any particular theory, the heterocyclic compound represented by Formula 1 may be partially restricted by the multiple resonance effect in a portion of Formula 1 (for example, a portion in which the electron-donating X1 atom is located at a meta position relative to the carbon atom bonded to the boron atom serving as the electron-accepting atom), and accordingly, the blue shift due to the multiple resonance may be prevented, thereby being useful in manufacturing an organic light-emitting device that emits light other than blue light.

[0298] In embodiments, multiple resonance can be viewed as essentially non-bonding (where the electron orbital distribution is confined to atoms), rather than the typical pi-conjugation in the related art. Pi-conjugation is essentially viewed as bonding, where the electron orbital distribution is confined by bonding so that the electron orbitals can connect to each other and electrons can move between them, resulting in an extension of the wavelength due to the delocalization property. From this perspective, the partial confinement of multiple resonance can be understood as an extension of the partial conjugation, and thus can cause delocalization and an extension of the wavelength, shifting the emission color toward the green wavelength.

[0299] Accordingly, when the heterocyclic compound represented by Formula 1 is applied to an organic light-emitting device, the driving voltage can be reduced, and the color purity, luminous efficiency, and lifespan characteristics can be improved. For example, when the emission layer of an organic light-emitting device includes the heterocyclic compound represented by Formula 1, a green organic light-emitting device with low driving voltage, high color purity, high luminous efficiency, and long lifespan can be realized.

[0300] In an embodiment, the heterocyclic compound represented by Formula 1 may emit green light. In an embodiment, the heterocyclic compound represented by Formula 1 may emit green light having a maximum emission wavelength in a range of about 500 nm to about 550 nm. For example, the heterocyclic compound represented by Formula 1 may emit green light having a maximum emission wavelength in a range of about 510 nm to about 540 nm. However, the embodiment is not limited thereto. Accordingly, the heterocyclic compound represented by Formula 1 may be used to manufacture an organic light-emitting device that emits green light.

[0301] In an embodiment, the heterocyclic compound represented by Formula 1 may emit deep green light having a maximum emission wavelength within a range of 520 nm to about 535 nm.

[0302] Those of ordinary skill in the art can recognize methods for synthesizing the heterocyclic compound represented by Formula 1 by referring to the examples provided below.

[0303] In an embodiment,

[0304] The first electrode of the organic light-emitting device may be an anode.

[0312] In an embodiment, the emission layer may include the heterocyclic compound represented by Formula 1. In an embodiment, the emission layer may emit green light having a maximum emission wavelength within a range of about 500 nm to about 550 nm.

[0313] In an embodiment, the emission layer of the organic light-emitting device may further include a dopant and a host, and the dopant may include a heterocyclic compound represented by Formula 1. For example, the heterocyclic compound represented by Formula 1 may be used as the dopant. The emission layer may emit, for example, green light. The green light may have a maximum emission wavelength in the range of, for example, about 500 nm to about 550 nm.

[0314] In an embodiment, the emission layer may emit deep green light having a maximum emission wavelength within a range of about 520 nm to about 535 nm.

[0315] In an embodiment, the emission layer may include a host and a dopant.

[0316] In an embodiment, in the emission layer, the amount of the host may be greater than the amount of the dopant based on weight.

[0317] In an embodiment, the host may include a silicon-containing compound, a phosphine oxide-containing compound, or any combination thereof.

[0318] In embodiments, the subject may be a subject described herein.

[0319] Therefore, a light-emitting device (eg, an organic light-emitting device) including the heterocyclic compound represented by Formula 1 may have high color purity, high luminous efficiency, low driving voltage, and long lifespan characteristics.

[0320] In an embodiment, the heterocyclic compound represented by Formula 1 may emit green light.

For example, the heterocyclic compound represented by Formula 1 may emit green light having a maximum emission wavelength in the range of about 515 nm to about 535 nm. For example, the heterocyclic compound represented by Formula 1 may emit green light having a maximum emission wavelength in the range of about 520 nm to about 530 nm.

[0321] In an embodiment, the heterocyclic compound represented by Formula 1 may have a color purity in which the bottom emission CIEx coordinate is in the range of about 0 to about 0.4. For example, the heterocyclic compound represented by Formula 1 may have a color purity in which the bottom emission CIEx coordinate is in the range of about 0.01 to about 0.35. In an embodiment, the heterocyclic compound represented by Formula 1 may have a color purity in which the bottom emission CIEy coordinate is in the range of about 0.35 to about 0.9. For example, the heterocyclic compound represented by Formula 1 may have a color purity in which the bottom emission CIEy coordinate is in the range of 0.4 to about 0.85. For example, the heterocyclic compound represented by Formula 1 may have a color purity in which the bottom emission CIEy coordinate is in the range of about 0.5 to about 0.83.

[0826] Examples 2 to 7 and Comparative Examples 1 to 4

[0827] An organic light-emitting device was manufactured in substantially the same manner as in Example 1, except that the compound shown in Table 1 was used as a dopant in forming the emission layer.

[0828]

[0829] Evaluation Example 1: Evaluation of Properties of Organic Light-Emitting Device

[0830] The organic light emitting devices of Examples 1 to 7 and Comparative Examples 1 to 4 were measured at 1,000 cd / m by using a Keithley SMU 236 meter and a luminance meter PR650. 2 The driving voltage, luminous efficiency, and maximum emission wavelength (λ max ) and lifespan (T 95 ), and the results are shown in Table 1. In Table 1, the driving voltage is expressed as a relative value relative to Comparative Example 1, and the lifespan (T 95 ) is a measure of the time (hr) taken for the brightness to reach 95% of the initial brightness, expressed as a relative value with respect to Comparative Example 1.

[0831] [Table 1]

[0832]

[0833] Referring to Table 1, it was confirmed that the organic light-emitting devices of Examples 1 to 7 had low driving voltage, high luminous efficiency, and remarkably excellent lifespan characteristics compared to the organic light-emitting devices of Comparative Examples 1 to 4.

[0834] Despite its large molecular size, Compound D used in Comparative Example 4 does not emit green light because the dibenzofuranyl groups adjacent to the boron atom are fused in a direction that complies with multiple resonance. For example, Compound D has a short wavelength, with a maximum solution-phase photoluminescence (PL) emission wavelength of only 497 nm. Therefore, due to its poor energy transfer capability, it is unsuitable for use as a final emitter (i.e., dopant). When used with a sensitizer, the light emitted by Compound D conflicts with the sensitizer, resulting in a broad emission spectrum and poor device characteristics.

[0835] According to embodiments, an organic light-emitting device including a heterocyclic compound may have low driving voltage, high luminous efficiency, high color purity, and long lifespan. In embodiments, high-quality electronic devices and consumer products may be manufactured using the organic light-emitting device.
