Description

Compounds for organic electric devices, materials for organic electric devices including the same, organic electric devices applying the same, and electronic devices thereof

[0001] The present invention relates to a compound for an organic electric device, a material for an organic electric device comprising the same, an organic electric device to which the same is applied, and an electronic device thereof.

[0002] In general, organic light emission refers to the phenomenon of converting electrical energy into light energy using organic materials. Organic electrical devices utilizing organic light emission typically have a structure that includes an anode, a cathode, and an organic layer between them. Here, the organic layer is often composed of a multilayer structure made of different materials to increase the efficiency and stability of the organic electrical device, and may consist of, for example, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer.

[0003] Materials used as organic layers in organic electronic devices can be classified according to their function into light-emitting materials and charge transport materials, such as hole injection materials, hole transport materials, electron transport materials, and electron injection materials. Furthermore, the light-emitting materials can be classified into high-molecular and low-molecular types based on molecular weight, and into fluorescent materials derived from the singlet excited state of electrons and phosphorescent materials derived from the triplet excited state of electrons based on the light emission mechanism. Additionally, light-emitting materials can be classified according to their emission color into blue, green, and red light-emitting materials, as well as yellow and orange light-emitting materials necessary to achieve better natural colors.

[0004] Meanwhile, when only a single material is used as a light-emitting material, intermolecular interactions cause the maximum emission wavelength to shift to a longer wavelength, resulting in reduced color purity or decreased device efficiency due to light attenuation effects. Therefore, a host / dopant system can be used as a light-emitting material to increase color purity and luminous efficiency through energy transfer. The principle is that when a small amount of a dopant, which has a smaller energy band gap than the host forming the light-emitting layer, is mixed into the light-emitting layer, excitons generated in the light-emitting layer are transported to the dopant, emitting high-efficiency light. At this time, since the wavelength of the host shifts to the wavelength range of the dopant, light of the desired wavelength can be obtained depending on the type of dopant used.

[0005] Currently, the portable display market is trending toward larger displays, which requires higher power consumption than that of conventional portable displays. Consequently, for portable displays that rely on the limited power source of batteries, power consumption has become a critical factor, and issues regarding efficiency and lifespan must also be resolved.

[0006] Efficiency, lifespan, and driving voltage are interrelated; as efficiency increases, the driving voltage relatively decreases. Consequently, a lower driving voltage reduces the crystallization of organic materials caused by Joule heating during operation, which in turn tends to extend lifespan. However, simply improving the organic layers does not guarantee maximum efficiency. This is because both long lifespan and high efficiency can be achieved simultaneously when the energy levels and T1 values ​​between the organic layers, along with the intrinsic properties of the materials (such as mobility and interfacial characteristics), form an optimal combination.

[0007] Therefore, there is a need to develop light-emitting materials that possess high thermal stability and can efficiently achieve charge balance within the emissive layer. In other words, to fully realize the excellent characteristics of organic electronic devices, it is essential that the materials constituting the organic layer within the device—such as hole injection materials, hole transport materials, light-emitting materials, electron transport materials, and electron injection materials—be supported by stable and efficient materials; among these, the development of host materials for the emissive layer is particularly necessary.

[0008] The present invention aims to provide a compound for an organic electric device capable of lowering the driving voltage of the device and improving the luminous efficiency and lifespan of the device, a material for an organic electric device including the same, an organic electric device to which the same is applied, and an electronic device thereof.

[0047] In this specification, the 'group name' corresponding to the aryl group, arylene group, heterocyclic group, etc., which are exemplified as examples of each symbol and its substituent, may be written as the 'name of the group reflecting the valence,' or it may be written as the 'name of the parent compound.' For example, in the case of 'phenanthrene,' a type of aryl group, the group name may be written by distinguishing the valence, such as 'phenanthrile' for the monovalent group and 'phenanthrillene' for the divalent group, but it may also be written as the parent compound name 'phenanthrene' regardless of the valence. Similarly, in the case of pyrimidine, it may be written as 'pyrimidine' regardless of the valence, or it may be written as the 'name of the group' corresponding to the valence, such as pyrimidinyl group for monovalent and pyrimidinyllene for divalent.

[0048] In addition, when describing compound names or substituent names in this specification, numbers or alphabets indicating positions may be omitted. For example, pyrido[4,3-d]pyrimidine may be described as pyridopyrimidine, benzofuro[2,3-d]pyrimidine as benzofuropyrimidine, 9,9-dimethyl-9H-fluorene as dimethylfluorene, etc. Accordingly, both benzo[g]quinoxaline and benzo[f]quinoxaline may be described as benzoquinoxaline.

[0051] Here, if a is an integer of 0, the substituent R 1 ≡ indicates absence; that is, when a is 0, it means that hydrogen is bonded to all carbons forming the benzene ring, in which case the chemical formula or compound can be written without indicating the hydrogen bonded to the carbons. Additionally, when a is an integer of 1, one substituent R 1 It bonds to any one of the carbons forming the benzene ring, and when a is an integer of 2 or 3, it can bond, for example, as follows; when a is an integer of 4 to 6, it bonds to the carbons of the benzene ring in a similar manner; and when a is an integer greater than or equal to 2, R 1 They may be the same or different from each other.

Furthermore, in describing the present invention, if it is determined that a detailed description of related known components or functions could obscure the essence of the invention, such detailed description is omitted.

[0072] In describing the components of the present invention, terms such as first, second, A, B, (a), (b), etc., may be used. These terms are intended merely to distinguish the components from other components, and the nature, order, or sequence of the components is not limited by these terms. Where it is stated that a component is "connected," "combined," or "joined" to another component, it should be understood that the component may be directly connected or joined to the other component, but that another component may also be "connected," "combined," or "joined" between each component.

[0073] Furthermore, when it is stated that a component, such as a layer, membrane, region, or plate, is "on" or "on" another component, it should be understood that this includes not only the case where it is "directly on" another component, but also the case where there is another component in between. Conversely, when it is stated that a component is "directly on" another part, it should be understood that this means there is no other part in between.

[0074] FIGS. 1 to 3 are exemplary diagrams of an organic electric device according to an embodiment of the present invention.

[0075] Referring to FIG. 1, an organic electric device (100) according to one embodiment of the present invention comprises a first electrode (110) formed on a substrate (not shown), a second electrode (170), and an organic layer formed between the first electrode (110) and the second electrode (170), and may also include an inorganic layer between the first electrode (110) and the second electrode (120).

[0076] For example, the first electrode (110) may be an anode (positive electrode) and the second electrode (170) may be a cathode (negative electrode), and in the case of an invert type, the first electrode may be a cathode and the second electrode may be an anode.

[0077] The above organic layer refers to a layer containing at least one organic material. For example, the organic layer may include a hole injection layer (120), a hole transport layer (130), a light-emitting layer (140), an electron transport layer (150), and an electron injection layer (160). However, the electron injection layer (160) may be an inorganic layer that does not contain organic material.

[0078] Specifically, a hole injection layer (120), a hole transport layer (130), a light-emitting layer (140), an electron transport layer (150), and an electron injection layer (160) can be sequentially formed on the first electrode (110).

[0079] Preferably, a light efficiency improvement layer (180) may be formed on one side of the first electrode (110) or the second electrode (170) that does not come into contact with an organic layer or an inorganic layer, and when the light efficiency improvement layer (180) is formed, the light efficiency of the organic electric device may be improved.

[0080] For example, a light efficiency improvement layer (180) may be formed on the second electrode (170). In the case of a top-emission organic light-emitting device, the formation of the light efficiency improvement layer (180) can reduce optical energy loss caused by SPPs (surface plasmon polaritons) at the second electrode (170), and in the case of a bottom-emission organic light-emitting device, the light efficiency improvement layer (180) can perform a buffering role for the second electrode (170).

[0081] A buffer layer (210) or a light-emitting auxiliary layer (220) may be further formed between the hole transport layer (130) and the light-emitting layer (140), and this will be explained with reference to FIG. 2.

[0082] Referring to FIG. 2, an organic electric device (200) according to another embodiment of the present invention may include a hole injection layer (120), a hole transport layer (130), a buffer layer (210), a light-emitting auxiliary layer (220), a light-emitting layer (140), an electron transport layer (150), an electron injection layer (160), and a second electrode (170) formed sequentially on a first electrode (110), and a light efficiency improvement layer (180) may be formed on the second electrode.

[0083] Although not shown in FIG. 2, an electron transport assist layer may be further formed between the light-emitting layer (140) and the electron transport layer (150).

[0084] In addition, according to another embodiment of the present invention, the organic layer may be in the form of a plurality of stacks including a hole transport layer, a light-emitting layer, and an electron transport layer. This will be explained with reference to FIG. 3.

[0085] Referring to FIG. 3, in another embodiment of the present invention, an organic electric device (300) may have two or more sets of stacks (ST1, ST2) of organic layers formed in multiple layers between a first electrode (110) and a second electrode (170), and a charge generating layer (CGL) may be formed between the stacks of organic layers.

[0086] Specifically, an organic electric device according to one embodiment of the present invention may include a first electrode (110), a first stack (ST1), a charge generation layer (CGL), a second stack (ST2), a second electrode (170), and a light efficiency improvement layer (180).

[0087] The first stack (ST1) is an organic layer formed on the first electrode (110), which may include a first hole injection layer (320), a first hole transport layer (330), a first light-emitting layer (340), and a first electron transport layer (350), and the second stack (ST2) may include a second hole injection layer (420), a second hole transport layer (430), a second light-emitting layer (440), and a second electron transport layer (450). Thus, the first stack and the second stack may be organic layers having the same stacking structure, but they may also be organic layers having different stacking structures.

[0088] A charge generation layer (CGL) may be formed between the first stack (ST1) and the second stack (ST2). The charge generation layer (CGL) may include a first charge generation layer (360) and a second charge generation layer (361). This charge generation layer (CGL) is formed between the first light-emitting layer (340) and the second light-emitting layer (440) to increase the current efficiency generated in each light-emitting layer and to facilitate the smooth distribution of charge.

[0089] The first light-emitting layer (340) may include a light-emitting material comprising a blue fluorescent dopant in a blue host, and the second light-emitting layer (440) may include a material doped with a greenish yellow dopant and a red dopant in a green host, but the materials of the first light-emitting layer (340) and the second light-emitting layer (440) according to the embodiment of the present invention are not limited thereto.

[0090] In FIG. 3, n can be an integer from 1 to 5, and when n is 2, a charge generation layer (CGL) and a third stack can be additionally stacked on the second stack (ST2).

[0091] When multiple light-emitting layers are formed by a multilayer stack structure method as shown in Fig. 3, it is possible to manufacture an organic electroluminescent device that emits white light through the mixing effect of light emitted from each light-emitting layer, as well as an organic electroluminescent device that emits light of various colors.

[0092] A compound represented by Formula 1-1 or Formula 1-2 of the present invention, or a material for an organic electric device containing Formula 1 and Formula I, may be included in an organic layer. For example, a compound represented by Formula 1-1 or Formula 1-2 of the present invention, or a material for an organic electric device containing Formula 1 and Formula I, may be used as a material for a hole injection layer (120, 320, 420), a hole transport layer (130, 330, 430), a buffer layer (210), a light-emitting auxiliary layer (220), an electron transport layer (150, 350, 450), a light-emitting layer (140, 340, 440), or a light efficiency improvement layer (180), but preferably may be used as a material for a light-emitting layer (140, 340, 440).

[0093] Even with identical or similar cores, the band gap, electrical properties, and interfacial properties can vary depending on which substituent is attached at which location; therefore, research on the selection of cores and the combination of sub-substituents attached thereto is necessary. In particular, long lifespan and high efficiency can be achieved simultaneously when the energy levels and T1 values ​​between each organic layer, along with the intrinsic properties of the material (mobility, interfacial properties, etc.), form an optimal combination.

[0094] Accordingly, in the present invention, by using a compound represented by Formula 1-1 or Formula 1-2, or a material for an organic electric device containing Formula 1 and Formula I as a material for the light-emitting layer (140, 340, 440), the energy level and T1 value between each organic layer, and the intrinsic properties of the material (mobility, interfacial properties, etc.) can be optimized to simultaneously improve the lifespan and efficiency of the organic electric device.

[0095] An organic electroluminescent device according to one embodiment of the present invention may be manufactured using various deposition methods. It may be manufactured using deposition methods such as PVD or CVD. For example, it may be manufactured by forming an anode (110) by depositing a metal or a conductive metal oxide or an alloy thereof on a substrate, forming an organic layer including a hole injection layer (120), a hole transport layer (130), a light-emitting layer (140), an electron transport layer (150), and an electron injection layer (160) on the anode, and then depositing a material that can be used as a cathode (170) on the anode. Additionally, a light-emitting auxiliary layer (220) may be further formed between the hole transport layer (130) and the light-emitting layer (140), and an electron transport auxiliary layer (not shown) may be further formed between the light-emitting layer (140) and the electron transport layer (150), or it may be formed in a stack structure as described above.

[0096] In addition, the organic layer can be manufactured with fewer layers by using various polymer materials and by a solution process or solvent process other than a deposition method, such as a spin coating process, nozzle printing process, inkjet printing process, slot coating process, dip coating process, roll-to-roll process, doctor blading process, screen printing process, or thermal transfer method. Since the organic layer according to the present invention can be formed in various ways, the scope of the rights of the present invention is not limited by the method of formation.

[0097] An organic electric device according to one embodiment of the present invention may be a front-emitting type, a back-emitting type, or a double-sided emitting type depending on the material used.

[0098] In addition, an organic electric device according to one embodiment of the present invention may be selected from the group consisting of an organic electroluminescent device, an organic solar cell, an organic photosensitive material, an organic transistor, a device for monochromatic lighting, and a device for a quantum dot display.

[0099] Another embodiment of the present invention may include a display device comprising the organic electric element of the present invention described above, and an electronic device comprising a control unit that controls the display device. In this case, the electronic device may be a current or future wired or wireless communication terminal and includes all electronic devices such as mobile communication terminals such as mobile phones, navigation systems, game consoles, various TVs, and various computers.

[0518] Although synthetic examples of compounds represented by Chemical Formula 1 and Chemical Formula I have been described above, these are all based on the Buchwald-Hartwig cross-coupling reaction, Miyaura boration reaction, Suzuki cross-coupling reaction, Intramolecular acid-induced cyclization reaction (J. Mater. Chem. 1999, 9, 2095), Pd(II)-catalyzed oxidative cyclization reaction (Org. Lett. 2011, 13, 5504), and PPh3-mediated reductive cyclization reaction (J. Org. Chem. 2005, 70, 5014), and it will be easily understood by those skilled in the art that the above reaction proceeds even if other substituents defined in Chemical Formula 1 or Chemical Formula I are attached in addition to the substituents specified in the specific synthetic examples.

[0519] Manufacturing evaluation of organic electrical devices

[0520] [Example 1] Red organic electroluminescent device (phosphor host)

[0521] A hole injection layer with a thickness of 10 nm is formed by vacuum depositing N-([1,1'-biphenyl]-4-yl)-9,9-dimethyl-N-(4-(9-phenyl-9H-carbazol-3-yl)phenyl)-9H-fluoren-2-amine (hereinafter referred to as Compound A) and 4,4',4"-((1E,1'E,1"E)-cyclopropane-1,2,3-triylidenetris(cyanomethaneylylidene))tris(2,3,5,6-tetrafluorobenzonitrile) (hereinafter referred to as Compound B) on an ITO layer (anode) formed on a glass substrate. At this time, Compound B is doped such that the weight ratio of Compound A to Compound B is 98:2.

[0522] Subsequently, compound A is vacuum-deposited on the hole injection layer to form a hole transport layer with a thickness of 110 nm.

[0523] Subsequently, N on the aforementioned hole transport layer 7 -(dibenzo[b,d]thiophen-2-yl)-N 2 ,N 2 ,N 7 -triphenyldibenzo[b,d]thiophene-2,7-diamine is vacuum-deposited to form a 10 nm thick light-emitting auxiliary layer.

[0524] Subsequently, a mixture host of the compound P-1 (first host) and the compound N-81 (second host) of the present invention mixed in a weight ratio of 5:5 and a dopant bis-(1-phenylisoquinolyl)iridium(Ⅲ)acetylacetonate (hereinafter abbreviated as '(piq)2Ir(acac)') are vacuum deposited on the light-emitting auxiliary layer to form a light-emitting layer with a thickness of 30 nm. At this time, the dopant is doped so that the weight ratio of the host to the dopant is 95:5.

[0525] Subsequently, 2-(4'-(9,9-dimethyl-9H-fluoren-2-yl)-[1,1'-biphenyl]-3-yl)-4,6-diphenyl-1,3,5-triazine is vacuum-deposited on the light-emitting layer to form a hole-blocking layer with a thickness of 10 nm.

[0526] Subsequently, a mixture of 2,7-bis(4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)naphthalene and (8-quinolinolato)lithium in a weight ratio of 5:5 is vacuum-deposited on the hole-blocking layer to form an electron transport layer with a thickness of 30 nm.

[0527] Subsequently, a compound (8-quinolinolato)lithium is vacuum-deposited on the electron transport layer to form an electron injection layer with a thickness of 0.2 nm, and then Al is deposited to form a cathode with a thickness of 150 nm.

[0528] [Examples 2] to [Examples 59]

[0529] An organic electroluminescent device was fabricated in the same manner as Example 1, except that compounds listed in Table 5 below were used as the first and second hosts of the light-emitting layer.

[0530] [Comparative Example 1] to [Comparative Example 3]

[0531] An organic electroluminescent device was fabricated in the same manner as Example 1, except that one of the following comparative compounds A to C was used as the first host of the light-emitting layer.

[0532] <Comparison Compound A> <Comparison Compound B> <Comparison Compound C>

[0533]

[0534] Electroluminescence (EL) characteristics were measured using a PR-650 from Photoresearch by applying a forward-bias DC voltage to each organic electroluminescent device prepared according to Examples 1 to 59 and Comparative Examples 1 to 3 of the present invention, and 2500 cd / m² 2 T95 was measured at reference brightness using a lifetime measuring device manufactured by MaxScience. The measurement results are shown in Table 5 below.

[0535] This measuring device is not affected by the possibility of daily fluctuations in deposition rate, vacuum quality, or other parameters, and can evaluate new performance by comparing it with a control compound under the same conditions. During the evaluation, since one batch contains four identically prepared OLEDs including a control compound, and the performance of a total of 12 OLEDs across three batches is evaluated individually, the experimental results obtained in this way have statistical significance.

[0537] As can be seen from Table 5 above, when a mixed host of the compound of Formula 1 of the present invention and the compound of Formula 1 is used, the driving voltage, luminous efficiency, and lifespan of the organic electroluminescent device are significantly improved compared to when one of Comparative Compounds A to C, which have a basic framework similar to the compound of Formula 1 of the present invention, is used as a component of the mixed host. In the case of Comparative Compound A, it is an amine compound structurally similar to the compound of Formula 1 of the present invention, but the condensation position of the 5-condensed ring, which is one of the amine substituents, is different. Due to this difference in condensation position, as can be confirmed below, there is a significant difference in the distance between the heteroatom of the 5-condensed ring and the aromatic ring (benzene) on the side where the amine is substituted.

[0538]

[0539] Therefore, in the case of the compound of Formula 1 of the present invention, the π orbital overlap through the non-covalent electron pairs of the heteroatoms of the 5-condensed ring is formed more strongly compared to comparative compound A. As a result, the distance between compounds becomes closer during device fabrication, allowing for smooth Dexter Energy transfer and improving the charge balance of the emissive layer, which appears to significantly improve the performance of the device.

[0540] Comparative compounds B and C contain a 5-condensed ring identical to Formula 1 of the present invention, but Comparative compound B has a heterocyclic ring substituted on an amine that differs from the compound of the present invention, and Comparative compound C has an additional amine group substituted on the 5-condensed ring, so the total number of amine groups differs from the compound of the present invention. As a result, the energy level and Tg, etc., differ significantly from the compound represented by Formula 1 of the present invention and Comparative compounds B and C, respectively, and it appears that this difference also affected the performance of the device.

[0541] In particular, among the compounds represented by Chemical Formula 1 of the present invention, Ar 2 It can be confirmed that the performance of the device is significantly improved when a compound is used as a host that includes a dibenzofuran or substituted dibenzothiophene substituted with a deuterium or aryl substituent, such as the compound of chemical formula B, i.e., the compound represented by chemical formula 1-1, or a naphthobenzofuran or naphthobenzothiophene moiety in which benzene is condensed to a dibenzofuran or dibenzothiophene moiety.

[0542] These results suggest that the stability of the structure itself and the charge transfer capability are enhanced due to the effect of the aforementioned π orbital overlap, and as a result, the performance of the device is also significantly improved.

[0543] [Example 60]

[0544] A hole injection layer with a thickness of 60 nm is formed by vacuum depositing N1-(naphthalen-2-yl)-N4, N4-bis(4-(naphthalen-2yl(phenyl)amino)phenyl)-N1-phenylbenzene-1,4-diamine (hereinafter referred to as 2-TNATA) on an ITO layer (anode) formed on a glass substrate.

[0545] Subsequently, 4,4-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (hereinafter referred to as NPD) is vacuum-deposited on the hole injection layer to form a hole transport layer with a thickness of 60 nm.

[0546] Subsequently, tris(4-(9H-carbazol-9-yl)phenyl)amine (hereinafter referred to as TCTA) is vacuum-deposited on the hole transport layer to form a 20 nm thick light-emitting auxiliary layer.

[0547] Subsequently, a mixture host of the compound P-42 (first host) and the compound N-33 (second host) of the present invention mixed in a weight ratio of 5:5 and a dopant (piq)2Ir(acac) are vacuum-deposited on the light-emitting auxiliary layer to form a light-emitting layer with a thickness of 30 nm. At this time, the dopant is doped so that the weight ratio of the host to the dopant is 95:5.

[0548] Subsequently, (1,1'-bisphenyl)-4-oleato)bis(2-methyl-8-quinolineoleato)aluminum (hereinafter referred to as BAlq) is vacuum deposited on the above-mentioned light-emitting layer to form a hole-blocking layer with a thickness of 10 nm.

[0549] Subsequently, Tris(8-hydroxyquinolinato)aluminium (hereinafter referred to as Alq3) is vacuum-deposited on the hole-blocking layer to form an electron transport layer with a thickness of 40 nm.

[0550] Subsequently, a compound LiF is vacuum-deposited on the electron transport layer to form an electron injection layer with a thickness of 0.2 nm, and then Al is deposited to form a cathode with a thickness of 150 nm.

[0552] An organic electroluminescent device was fabricated in the same manner as in Example 60, except that the compounds listed in Table 6 below were used as the first and second hosts of the light-emitting layer.

[0553] A forward-bias DC voltage was applied to each organic electroluminescent device prepared according to Examples 60 to 70 and Comparative Examples 4 and 5 of the present invention, and the electroluminescent (EL) characteristics were measured using a PR-650 from Photoresearch, and 2500 cd / m² 2 T95 was measured at reference brightness using a lifetime measuring device manufactured by MaxScience. The measurement results are shown in Table 6 below.

[0554] This measuring device is not affected by the possibility of daily fluctuations in deposition rate, vacuum quality, or other parameters, and can evaluate new performance by comparing it with a control compound under the same conditions. During the evaluation, since one batch contains four identically prepared OLEDs including a control compound, and the performance of a total of 12 OLEDs across three batches is evaluated individually, the experimental results obtained in this way have statistical significance.

[0556] Looking at Table 6 above, it can be seen that the performance of the device is significantly improved when the compound of the present invention is used compared to when comparative compound A or comparative compound B is used as the first host. In addition, in the case of a compound in which an amine group is bonded to a specific position of Chemical Formula A in Chemical Formula 1 of the present invention, such as a compound represented by Chemical Formula 1-2 of the present invention, the distance between molecules becomes closer, and it can be confirmed that the performance of the device is significantly improved.

[0557] [Examples 71] to [Examples 75]

[0558] An organic electroluminescent device was fabricated in the same manner as in Example 60, except that as the host material of the light-emitting layer, a mixture of a first compound represented by Chemical Formula 1 (first host), a second compound represented by Chemical Formula I (second host), and a third compound represented by Chemical Formula H-1 or Chemical Formula H-2 (third host) mixed in a weight ratio of 5:3:2 was used.

[0559] A forward-bias DC voltage was applied to each organic electroluminescent device prepared according to Examples 71 to 75 of the present invention, and the electroluminescent (EL) characteristics were measured using a PR-650 from Photoresearch, and 2500 cd / m² 2 T95 was measured at reference brightness using a lifetime measuring device manufactured by MaxScience. The measurement results are shown in Table 7 below.

[0560] This measuring device is not affected by the possibility of daily fluctuations in deposition rate, vacuum quality, or other parameters, and can evaluate new performance by comparing it with a control compound under the same conditions. During the evaluation, since one batch contains four identically prepared OLEDs including a control compound, and the performance of a total of 12 OLEDs across three batches is evaluated individually, the experimental results obtained in this way have statistical significance.

[0562] Looking at Table 7 above, it can be seen that the performance of the organic electroluminescent device is significantly improved even when using a mixed host that includes a third compound with a structure different from the compounds represented by Chemical Formula 1 and Chemical Formula I of the present invention. As can be seen from the results of Tables 5 to 7 above, even among compounds with similar compositions, the compound of the present invention, which satisfies all complex factors such as the type of specific substituent and the substitution position of the substituent, exhibits a significant effect in the organic electroluminescent device compared to other comparative compounds. Through this, it can be seen that the compound of the present invention exhibits a significant effect in the organic electroluminescent device compared to simple structural isomers or compounds with similar compositions that are not described in this specification.

[0563] These results suggest that even for compounds with similar molecular components, properties such as hole characteristics, photoelectric efficiency, energy levels, hole injection and mobility characteristics, hole-electron charge balance, volume density, and intermolecular distance can vary significantly and unpredictably depending on the type and position of the substituents. Furthermore, they indicate that device performance may vary due to complex factors rather than being influenced by a single configuration alone.

[0564] The foregoing description is merely illustrative of the present invention, and those skilled in the art to which the present invention pertains will be able to make various modifications without departing from the essential characteristics of the present invention. The scope of protection of the present invention shall be interpreted by the claims below, and all technology within an equivalent scope shall be interpreted as being included within the scope of rights of the present invention.
