Description

Compounds for organic electric devices, organic electric devices using the same, and electronic devices thereof

[0001] The present invention relates to a compound for an organic electric device, an organic electric device using the same, 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, an organic electric device using the same, and an electronic device thereof.

[0009] In one aspect, the present invention provides a compound represented by the following chemical formula.

[0015] In another aspect, the present invention provides an organic electric device and an electronic device thereof, comprising a material for an organic electric device that includes a compound of Formula 1 or contains a compound of Formula 1 and Formula I.

[0016] In another aspect, the present invention provides a method for recovering a compound represented by the above chemical formula 1.

[0034]

[0035] The term "spyro compound" as used in this specification refers to a compound having a "spyro linkage," where a spyro linkage is a connection formed by two rings sharing only one atom. In this case, the atom shared between the two rings is called a "spyro atom," and depending on the number of spyro atoms contained in a compound, they are respectively called "monospyro-," "diespyro-," and "trispyro-" compounds.

[0036] The term “heterocyclic group” as used in this specification includes not only aromatic heterocyclic groups such as “heteroaryl groups” or “heteroarylene groups” but also non-aromatic heterocyclic groups, and unless otherwise noted, means a ring having 2 to 60 carbon atoms containing one or more heteroatoms, but is not limited thereto. The term “heteroatom” as used in this specification refers to an element other than carbon, such as N, O, S, P, or Si, unless otherwise noted, and may include a heteroatom group such as SO2, P=O, etc., as in the following compounds, instead of carbon forming the ring.

[0037]

[0038] In addition, heterocyclic rings include monocyclic, polycyclic, or condensed rings containing heteroatoms, and in the case of condensed rings, if at least one of the condensed rings is a ring containing a heteroatom, it is defined as a heterocyclic ring. For example, heterocyclic rings such as furan, dihydrofuran, thiophene, pyrrole, pyridine, etc., and aromatic rings such as benzene, naphthalene, phenanthrene, etc., or aliphatic rings such as cyclopentane, cyclohexane, etc., are condensed to form a condensed ring, and in the case of a spiro compound, at least one ring contains a heteroatom, it is also a heterocyclic ring.

[0039] As used in this specification, the term "aliphatic ring" refers to a cyclic hydrocarbon excluding aromatic hydrocarbons, and includes single rings, polycyclic rings, condensed rings, spiro compounds, etc. Unless otherwise stated, it refers to a ring having 3 to 60 carbon atoms, but is not limited thereto. In particular, in this specification, an aliphatic ring (group) is defined as a hydrocarbon ring that does not contain any aromatic rings. Therefore, not only saturated hydrocarbon rings such as cycloalkyl groups, but also cases where there is one or more double bonds within the ring are considered to correspond to an aliphatic ring if they are not aromatic hydrocarbons.

[0040] Unless otherwise specified, the terms “fusion ring(group)” or “condensation ring(group)” as used in this specification refer to a ring in which an aliphatic ring and an aromatic hydrocarbon (aromatic ring or aryl ring) are condensed together, and unless otherwise specified, refer to a ring in which an aliphatic ring having 3 to 60 carbon atoms and an aromatic hydrocarbon having 6 to 60 carbon atoms are condensed together.

[0041] 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.

[0042] 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.

[0043] In addition, unless explicitly stated otherwise, the chemical formulas used in the present invention are applied identically to the definitions of substituents by the definitions of the indices of the following chemical formulas.

[0044]

[0045] 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.

[0046]

[0047] In addition, unless otherwise stated in this specification, the term "ring" means an aryl ring, a heteroaryl ring, a fluorene ring, an aliphatic ring, a fused ring, etc., and terms such as "number-ring," "number-condensed ring," or "number-fused ring" mean a form in which rings corresponding to the number are fused together, and "number-ring" may mean a ring shape. For example, naphthalene corresponds to a 2-ring, a 2-condensed ring, or a 2-fused ring, anthracene corresponds to a 3-ring, a 3-condensed ring, or a 3-fused ring, thiophene or furan corresponds to a 5-membered heteroring, and benzene or pyridine corresponds to a 6-membered aromatic ring.

[0048] Additionally, unless otherwise described in this specification, the rings formed by combining adjacent groups are C6~C 60 Aromatic ring; fluorene group; C2~C comprising at least one heteroatom among O, N, S, Si and P 60 The heterocyclic ring of; C3~C 60 aliphatic ring of; and C3~C 60 The aliphatic ring and C6~C 60The aromatic ring can be selected from a group of fused rings. Here, the aromatic ring can be an aryl ring, and the heteroring can include a heteroaryl ring.

[0049] Unless otherwise stated in this specification, the term "neighboring groups" includes, for example with the following chemical formula, R1 and R2, R2 and R3, R3 and R4, and R5 and R6, as well as R7 and R8 sharing one carbon, and may also include substituents bonded to ring constituent elements (such as carbon or nitrogen) that are not immediately adjacent, such as R1 and R7, R1 and R8, or R4 and R5. That is, if there are substituents on ring constituent elements such as immediately adjacent carbons or nitrogen, these may be neighboring groups; however, if no substituents are bonded to ring constituent elements at immediately adjacent positions, the substituents bonded to the next ring constituent element may be neighboring groups, and substituents bonded to the same ring constituent carbon may also be considered neighboring groups. In the following chemical formula, when substituents bonded to the same carbon, such as R7 and R8, bond to each other to form a ring, a compound containing a spiro moiety may be formed.

[0050]

[0051] Additionally, in this specification, the expression "neighboring units may combine to form a ring" is used with the same meaning as "neighboring units selectively combine to form a ring," and refers to the case where at least one pair of neighboring units combine to form a ring.

[0052] In addition, in this specification, the phrase "neighboring groups can combine with each other to form a ring" means that neighboring groups can consequently form a ring, and R 1 and R 2It is not assumed that the substituent contains an unsaturated bond, such as an alkenyl group or an alkyneyl group.

[0055] Hereinafter, a stacked structure of an organic electric device containing a compound of the present invention will be described with reference to FIGS. 1 to 3.

[0056] It should be noted that when assigning reference numerals to the components of each drawing, the same components are assigned the same reference numeral whenever possible, even if they are shown in different drawings. 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.

[0057] 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.

[0058] 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.

[0059] FIGS. 1 to 3 are exemplary diagrams of an organic electric device according to an embodiment of the present invention.

[0060] Referring to FIG. 1, an organic electric device (100) according to one embodiment of the present invention includes 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).

[0061] 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.

[0062] 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.

[0063] 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).

[0064] 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.

[0065] 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).

[0066] 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.

[0067] 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.

[0068] 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).

[0069] 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.

[0070] 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.

[0071] 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).

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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).

[0076] As shown in Fig. 3, when multiple light-emitting layers are formed by a multilayer stack structure, 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 to manufacture an organic electroluminescent device that emits light of various colors.

[0077] A compound represented by Formula 1 of the present invention or a mixture of a compound of Formula 1 and a compound of Formula I may be included in an organic layer. For example, a compound represented by Formula 1 of the present invention or a mixture of a compound of Formula 1 and a compound of 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 host for a light-emitting layer (140, 340, 440).

[0078] 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.

[0079] Accordingly, in the present invention, by using a compound represented by Formula 1 or a mixture of the compound of Formula 1 and the compound of Formula I as a host 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0406] 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.

[0409] 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.

[0410] Subsequently, compound A is vacuum-deposited on the hole injection layer to form a hole transport layer with a thickness of 110 nm.

[0411] 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.

[0412] Subsequently, a mixture host of the compound P-1 (first host) and the compound N-211 (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.

[0413] 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.

[0414] 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.

[0415] 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.

[0417] An organic electroluminescent device was fabricated in the same manner as in Example 1, except that the compound of the present invention listed in Table 5 was used as the host material of the light-emitting layer.

[0422] A forward-bias DC voltage was applied to the organic electroluminescent devices prepared according to Examples 1 to 34 and Comparative Examples 1 to 4 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 5 below.

[0423] 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.

[0425] As can be seen from Table 5 above, when the compound of the present invention is used as a host for the light-emitting layer, the driving voltage, luminous efficiency, and lifespan of the organic electroluminescent device can be significantly improved compared to when comparative compounds A to D, which have a basic framework similar to the compound of the present invention, are used. Comparative compound A is an amine compound structurally similar to the compound of the present invention, but the condensation position of the condensation ring introduced into the amine core is different. The compound of the present invention has benzophenanthrene introduced into the core, whereas comparative compound A has chrysene introduced into the core, so there is a structural difference. As the core structure differs, the hole characteristics of the compound acting as a hole-transporting host change, and as a result, it appears that the performance of the device is significantly improved when the compound of the present invention with benzophenanthrene introduced is used.

[0426] Comparative compounds B to D have structures similar to the compound of the present invention, but differ in whether an aryl group is substituted on dibenzothiophene. That is, the compound of the present invention has a substituent Ar on an X-containing heterocycle. 2 While the (aryl group) is substituted, Comparative Compounds B to D are not substituted with a separate substituent.

[0427] In addition, comparative compounds B and D are structurally different in that, unlike the compound of the present invention in which benzophenanthrene is directly bonded to an amine, a linker exists between benzophenanthrene and the amine.

[0428] To confirm the difference in energy levels of the compounds due to these differences, LUMO values ​​were measured using the DFT method (B3LYP / 6-31g(D)) of the Gaussian program. The measurement results are shown in Table 6 below.

[0429] Comparative compound BP-75 Comparative compound CP-85 Comparative compound DP-90 LUMO(eV)-1.414-1.319-1.420-1.366-1.398-1.319

[0430] Referring to Table 6 above, it can be seen that the compounds of the present invention have higher LUMO energy levels compared to the comparative compounds. The compounds of the present invention act as hole-transporting hosts involved in hole transport within the emissive layer as first host compounds. A low LUMO energy level of the hole-transporting host implies high electronic characteristics and can be interpreted as implying relatively low hole characteristics. In other words, the compounds of the present invention have higher hole characteristics compared to the comparative compounds, facilitating hole movement within the emissive layer, and consequently, it appears that the driving voltage and efficiency have been improved.

[0431] In addition, when the LUMO energy level of the first host is low, electrons entering from the electron transport layer to the light-emitting layer may move to the hole-transporting host instead of the electron-transporting host, which can affect the lifespan of the device. That is, the compound of the present invention, which has a higher LUMO energy level compared to comparative compounds, appears to effectively block electron movement to the hole-transporting host, resulting in a longer device lifespan.

[0432] Unlike comparative compounds B to D, the compounds of the present invention have an aryl group (Ar) in a heterocyclic ring containing X. 2It is characterized by the substitution of ) . As the aryl group is substituted in this way, intramolecular π-π stacking is created between the amine and another substituent, -L1-Ar1, and as a result, the overall hole movement within the emissive layer is accelerated, exhibiting a faster HOD (Hole On Device). In other words, it appears that efficiency and lifespan are improved because the charge balance between electrons and holes is well achieved within the emissive layer.

[0433] As examined above, when the light-emitting layer is composed of multiple host compounds, the characteristics differ depending on the types of the first and second hosts, and it can be seen that the driving voltage, efficiency, and lifespan vary depending on the ease of hole and electron injection and transport characteristics.

[0434] When the compound of the present invention is used in the emissive layer, the electron mobility of the electron-transporting host improves, causing the emissive region to shift toward the interface between the hole transport layer and the emissive layer. Consequently, it is expected that the degree of accumulation of holes flowing from the hole transport layer into the emissive layer will be reduced. In other words, it appears that efficiency and lifespan are improved as the charge balance between electrons and holes is well maintained within the emissive layer.

[0435] From Tables 5 and 6 above, it can be confirmed that even among compounds with similar compositions, the compounds of the present invention that satisfy all complex factors such as the type of substituent and the substitution position of the substituent exhibit a significant effect in organic electrical devices compared to other comparative compounds, and through this, it can be seen that the compounds of the present invention exhibit a significant effect in organic electrical devices compared to simple structural isomers or other compounds with similar compositions not described in this specification.

[0436] 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.

[0437] 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.
