Abstract
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] Generally, organic light emitting diodes (OLEDs) are devices that convert electrical energy into light energy using organic materials. Organic electronic devices utilizing the organic light emitting diode (OLED) phenomenon typically have a structure comprising an anode, a cathode, and an organic layer between them. These organic layers are often multilayered, composed of different materials, to enhance the efficiency and stability of the device. For example, these layers may include 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 into light-emitting materials and charge-transporting materials, such as hole injection materials, hole transport materials, electron transport materials, and electron injection materials, depending on their functions. In addition, the light-emitting materials can be classified into high-molecular and low-molecular types depending on their molecular weight, and can be classified into fluorescent materials derived from the singlet excited state of electrons and phosphorescent materials derived from the triplet excited state of electrons depending on their luminescence mechanism. In addition, light-emitting materials can be classified into blue, green, and red light-emitting materials depending on their luminescence color, and yellow and orange light-emitting materials required to realize better natural colors.
[0004] Meanwhile, when only one substance is used as a light-emitting material, the maximum light-emitting wavelength shifts to a longer wavelength due to intermolecular interactions, resulting in a decrease in color purity or a decrease in device efficiency due to light-emitting attenuation. Therefore, a host / dopant system can be used as a light-emitting material to increase color purity and light-emitting efficiency through energy transfer. The principle is that when a small amount of a dopant having 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, resulting in high-efficiency light emission. At this time, the wavelength of the host shifts to the wavelength of the dopant, so light of a desired wavelength can be obtained depending on the type of dopant used.
[0005] The current portable display market is trending toward larger displays, increasing in size. This demand for greater power consumption exceeds that of existing portable displays. Therefore, power consumption has become a crucial factor for portable displays, which rely on batteries as a limited power source. Efficiency and longevity also need to be addressed.
[0006] Efficiency, lifespan, and operating voltage are all interrelated. As efficiency increases, the operating voltage relatively decreases. As the operating voltage decreases, the crystallization of organic materials due to Joule heating generated during operation decreases, which tends to result in a longer lifespan. However, efficiency cannot be maximized simply by improving the organic layer. This is because long lifespan and high efficiency can be achieved simultaneously when the energy level and T1 value between each organic layer, and the intrinsic properties of the material (mobility, interfacial properties, etc.) are optimally combined.
[0007] Therefore, there is a need for the development of light-emitting materials that have high thermal stability and can efficiently achieve charge balance within the light-emitting layer. In other words, in order to fully demonstrate the excellent characteristics of organic electronic devices, the materials that make up the organic layers within the device, such as hole injection materials, hole transport materials, light-emitting materials, electron transport materials, and electron injection materials, must first be supported by stable and efficient materials, and among these, development of host materials for the light-emitting layer is particularly necessary.
[0008] The purpose of the present invention is to provide a compound for an organic electric device that can lower the driving voltage of the device and improve the luminous efficiency and lifespan of the device, an organic electric device using the same, and an electronic device thereof.

[0032] The terms "aryl group," "arylene group," and "aromatic ring" used herein mean a hydrocarbon aromatic ring group, each having 6 to 60 carbon atoms unless otherwise specified, but is not limited thereto. In the present invention, the aryl group or arylene group includes a monocyclic ring, a polycyclic ring, a condensed ring, and the like.
[0033] As used herein, the term "fluorenyl group" means a substituted or unsubstituted fluorenyl group, and "fluorenylene group" means a substituted or unsubstituted fluorenylene group. The fluorenyl group or fluorenylene group used in the present invention includes a spiro compound formed by R and R' bonding to each other in the structure below, and also includes a compound in which adjacent R" bonds to each other to form a ring. The "substituted fluorenyl group" and the "substituted fluorenylene group" mean that at least one of R, R', and R" in the structure below is a substituent other than hydrogen, and the number of R" in the chemical formula below may be 1 to 8. In the present specification, regardless of the valence, a fluorenyl group, a fluorenylene group, etc. may be described as a fluorene group or fluorene.
[0034]
[0035] The term "spiro compound" as used herein has a "spiro linkage," which means a linkage formed by two rings sharing only one atom. The atom shared between the two rings is called a "spiro atom," and depending on the number of spiro atoms contained in a compound, these are called "monospiro-," "dicepiro-," and "trispiro-" compounds, respectively.
[0036] The term "heterocyclic group" used herein includes not only aromatic heterocycles such as "heteroaryl group" or "heteroarylene group" but also non-aromatic heterocycles, and unless otherwise stated means, but is not limited to, a ring having 2 to 60 carbon atoms each containing one or more heteroatoms. The term "heteroatom" used herein, unless otherwise stated, represents an element other than carbon, such as N, O, S, P, or Si, and may include a heteroatom group such as SO2, P=O, etc. instead of carbon forming the ring, as in the following compounds.
[0037]
[0038] In addition, a heterocyclic group includes a monocyclic ring, polycyclic ring, or condensed ring containing a heteroatom, and in the case of a condensed ring, if at least one of the condensed rings is a ring containing a heteroatom, it is defined as a heterocyclic ring. For example, a condensed ring in which a heterocyclic ring such as furan, dihydrofuran, thiophene, pyrrole, pyridine, etc. and an aromatic ring such as benzene, naphthalene, phenanthrene, etc. are condensed, or an aliphatic ring such as cyclopentane, cyclohexane, etc. are condensed is also considered a heterocyclic ring, and a spiro compound in which at least one ring contains a heteroatom is also considered a heterocyclic ring.
[0039] The term "aliphatic ring" used in this specification refers to a cyclic hydrocarbon other than an aromatic hydrocarbon, including a monocyclic ring, a polycyclic ring, a condensed ring, a spiro compound, etc., and unless otherwise stated, refers to a ring having 3 to 60 carbon atoms, but is not limited thereto. In particular, an aliphatic ring (group) in this specification is defined as a hydrocarbon ring that does not contain any aromatic rings. Therefore, not only a saturated hydrocarbon ring such as a cycloalkyl group, but also a ring having one or more double bonds in the ring is considered to be an aliphatic ring as long as it is not an aromatic hydrocarbon.
[0040] The term "fused ring(group)" or "condensed ring(group)" used herein, unless otherwise stated, means a ring in which an aliphatic ring and an aromatic hydrocarbon (aromatic ring group or aryl ring) are condensed with each other, and unless otherwise stated, means 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 with each other.
[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 described as the 'group name reflecting the valence', or may be described as the 'parent compound name'. For example, in the case of 'phenanthrene', which is a type of aryl group, the name of the group may be described by distinguishing the valence, such as 'phenanthryl' for the monovalent 'group' and 'phenantrylene' for the divalent group, or it may be described as the parent compound name 'phenanthrene' regardless of the valence. Similarly, in the case of pyrimidine, it may be described as 'pyrimidine' regardless of the valence, or it may be described as the 'group name' of the corresponding valence, such as pyrimidinyl group for monovalent and pyrimidinylene for divalent.
[0042] In addition, in this specification, numbers or alphabets indicating positions may be omitted when describing compound names or substituent names. 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] Additionally, unless explicitly stated otherwise, the chemical formulas used in the present invention are applied in the same manner as the substituent definitions by the index definitions of the chemical formulas below.
[0044]
[0045] Here, if a is an integer of 0, the substituent R 1 means that it is absent, that is, when a is 0, it means that all the carbons forming the benzene ring are bonded with hydrogen, and in this case, the indication of hydrogen bonded to carbon can be omitted and the chemical formula or compound can be described. In addition, when a is an integer of 1, one substituent R 1It binds to one of the carbons forming the benzene ring, and when a is an integer of 2 or 3, it can bind as follows, for example, and when a is an integer of 4 to 6, it binds to the carbon of the benzene ring in a similar manner, and when a is an integer of 2 or more, R 1 may be the same or different.
[0046]
[0047] In addition, unless otherwise stated herein, a ring refers to an aryl ring, a heteroaryl ring, a fluorene ring, an aliphatic ring, a fused ring, etc., and a number-ring refers to a condensed ring, and a number-atom ring refers to a ring shape. For example, naphthalene corresponds to a two-ring condensed ring, anthracene corresponds to a three-ring condensed ring, thiophene and furan correspond to a five-membered heterocycle, and benzene and pyridine correspond to a six-membered aromatic ring.
[0048] In addition, unless otherwise stated in this specification, the rings formed by bonding adjacent groups to each other are C6~C 60 Aromatic ring group; Fluorenyl group; C2~C containing at least one heteroatom among O, N, S, Si and P 60 Heterocyclic group of; C3~C 60 Aliphatic ring group; and C3~C 60 Aliphatic ring and C6~C 60 The aromatic ring may be selected from the group consisting of a fused ring group. Here, the aromatic ring group may be an aryl ring, and the heterocyclic group may include a heteroaryl ring.
[0049] Unless otherwise stated herein, 'neighboring groups' includes, for example, R1 and R2, R2 and R3, R3 and R4, R5 and R6, as well as R7 and R8 sharing a carbon, and may also include substituents bonded to non-adjacent ring elements (carbon, nitrogen, etc.), such as R1 and R7, R1 and R8, or R4 and R5. That is, when there is a substituent on a ring element such as a carbon or nitrogen that is immediately adjacent, they can be neighboring groups, but when no substituent is bonded to the ring element at the immediately adjacent position, the substituent bonded to the next ring element can be a neighboring group, and substituents bonded to the same ring carbon can also be 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 including a spiro moiety can be formed.
[0050] In addition, in this specification, ‘adjacent groups can form a ring by bonding with each other’ means that adjacent groups can form a ring as a result, and it does not presuppose that R1 and R2 are substituents containing an unsaturated bond, such as an alkenyl group or an alkynyl group.
[0051] ,
[0052] Additionally, in this specification, the expression 'adjacent groups can combine with each other to form a ring' is used with the same meaning as 'adjacent groups combine with each other to selectively form a ring', and means a case where at least one pair of adjacent groups combine with each other to form a ring.
[0053] In addition, unless otherwise stated herein, substituents such as aryl group, arylene group, fluorenyl group, fluorenylene group, heterocyclic group, aliphatic ring group, fused ring group, alkyl group, alkenyl group, alkynyl group, alkoxy group, aryloxy group, alkylthio group, arylthio group, etc., rings formed by bonding adjacent groups to each other, etc., are each deuterium; halogen; cyano group; nitro group; siloxane group; C6-C 30 Aryl group of; Fluorenyl group; C2-C containing at least one heteroatom selected from the group consisting of O, N, S, Si and P 30 Heterocyclic group of; C3-C 30 Aliphatic ring group; C3~C 60 Aliphatic ring and C6~C 60 Fused ring group of aromatic ring; C1-C 20 alkyl group of; C2-C 20 alkenyl group of; C2-C 20 Alkynyl group of; C1-C 20 Alkoxy group of; C6-C 20 Aryloxy group of; C1-C 20 Alkylthio group of; C6-C 20 Arylthio group of; C1-C 20 Alkyl group or C6-C 20 A silane group substituted or unsubstituted with an aryl group; and C1-C 20 Alkyl group or C6-C 20 It may be substituted with one or more substituents selected from the group consisting of phosphine oxide groups substituted or unsubstituted with an aryl group.

[0055] Hereinafter, the laminated structure of an organic electric device including the compound of the present invention will be described with reference to FIGS. 1 to 3.
[0056] When assigning reference numerals to components in each drawing, it should be noted that identical components are assigned the same numerals whenever possible, even if they appear on different drawings. Furthermore, when describing the present invention, if a detailed description of a related known configuration or function is deemed likely to obscure the gist of the present invention, such detailed description will be omitted.
[0057] When describing components of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only intended to distinguish the components from other components, and the nature, order, or sequence of the components are not limited by the terms. When it is described that a component is "connected," "coupled," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but another component may also be "connected," "coupled," or "connected" between each component.
[0058] Furthermore, when a component such as a layer, membrane, region, or plate is said to be "on" or "over" another component, it should be understood that this includes not only the case where it is "directly on" the other component, but also the case where there are other components in between. Conversely, when a component is said to be "directly on" another part, it should be understood that there are no other components in between.
[0059] Figures 1 to 3 are exemplary diagrams of organic electric devices according to embodiments of the present invention.
[0060] Referring to FIG. 1, an organic electric element (100) according to one embodiment of the present invention includes a first electrode (110), a second electrode (170), and an organic layer formed between the first electrode (110) and the second electrode (170) formed on a substrate (not shown), and an inorganic layer may be included between the first electrode (110) and the second electrode (120).
[0061] For example, the first electrode (110) may be an anode, the second electrode (170) may be a cathode, and in the case of an inverted 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 an 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 a 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 is not in contact with the organic layer or the inorganic layer, and when the light efficiency improvement layer (180) is formed, the light efficiency of the organic electric element may be improved.
[0065] For example, a light efficiency improvement layer (180) can 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 due to SPPs (surface plasmon polaritons) in the second electrode (170), and in the case of a bottom emission organic light emitting device, the light efficiency improvement layer (180) can serve as a buffer 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), which will be described with reference to FIG. 2.
[0067] Referring to FIG. 2, an organic electric element (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) sequentially formed 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 auxiliary layer may be further formed between the light-emitting layer (140) and the electron transport layer (150).
[0069] Additionally, according to another embodiment of the present invention, the organic layer may be formed in a form in which a plurality of stacks including a hole transport layer, a light-emitting layer, and an electron transport layer are formed. This will be described with reference to FIG. 3.
[0070] Referring to FIG. 3, an organic electric element (300) according to another embodiment of the present invention may have two or more sets of stacks (ST1, ST2) of organic layers formed of multiple layers formed between a first electrode (110) and a second electrode (170), and a charge generation 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: Charge Generation Layer), 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). In this way, the first stack and the second stack may be organic layers having the same stacked structure, but may also be organic layers having different stacked 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 smoothly distribute charges.
[0074] The first light-emitting layer (340) may include a light-emitting material including 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] When a plurality of light-emitting layers are formed by a multi-layer stack structure as shown in Fig. 3, not only can an organic light-emitting device that emits white light be manufactured by the mixing effect of the light emitted from each light-emitting layer, but an organic light-emitting device that emits light of various colors can also be manufactured.
[0077] The compound represented by the chemical formula 1 of the present invention or a mixture of the compound of the chemical formula 1 and the compound of the chemical formula I may be included in an organic layer. For example, the compound represented by the chemical formula 1 of the present invention or a mixture of the compound of the chemical formula 1 and the compound of the chemical 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 may preferably be used as a host for the light-emitting layer (140, 340, 440).
[0078] Even if the core is identical or similar, the band gap, electrical properties, and interface properties can vary depending on which substituent is bonded at which position. Therefore, research on the selection of the core and the combination of sub-substituents bonded to it is necessary. In particular, when the energy level and T1 value between each organic layer and the intrinsic properties of the material (mobility, interface properties, etc.) are optimally combined, long life and high efficiency can be achieved simultaneously.
[0079] Therefore, in the present invention, by using a compound represented by chemical formula 1 or a mixture of a compound of chemical formula 1 and a compound of chemical formula I as a host of a light-emitting layer (140, 340, 440), the energy level and T1 value between each organic layer, and the inherent properties of the material (mobility, interface properties, etc.) can be optimized, thereby simultaneously improving the lifespan and efficiency of the organic electric device.
[0080] An organic light emitting diode according to an embodiment of the present invention may be manufactured using various deposition methods. It may be manufactured using a deposition method 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) thereon, and then depositing a material that can be used as a cathode (170) thereon. In addition, an emission 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 emission layer (140) and the electron transport layer (150), or may be formed in a stack structure as described above.
[0081] In addition, the organic layer can be manufactured with a smaller number of layers by using various polymer materials and a solution process or solvent process other than a deposition method, such as a spin coating process, a nozzle printing process, an inkjet printing process, a slot coating process, a dip coating process, a roll-to-roll process, a doctor blading process, a screen printing process, or a thermal transfer method. Since the organic layer according to the present invention can be formed by various methods, the scope of the present invention is not limited by the formation method.
[0082] An organic electric device according to one embodiment of the present invention may be a front-emitting, back-emitting, or double-sided emitting type depending on the material used.
[0083] In addition, the organic electric device according to one embodiment of the present invention may be selected from the group consisting of an organic light-emitting device, an organic solar cell, an organic photoconductor, an organic transistor, a device for monochrome lighting, and a device for quantum dot display.
[0084] Another embodiment of the present invention may include a display device including the organic electric element of the present invention described above, and an electronic device including a control unit for controlling 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 cell phones, navigation systems, game consoles, various TVs, and various computers.

[0445] Although the above has been described with respect to synthetic examples of compounds represented by Chemical Formula 1 and Chemical Formula I, these are all based on 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 those skilled in the art will easily understand that the above reaction proceeds even if a substituent other than the substituent specified in the specific synthetic example is combined in Chemical Formula 1 or Chemical Formula I.
[0446] Manufacturing and evaluation of organic electronic devices
[0447] [Example 1] Red organic electroluminescent device (phosphorescent host)
[0448] 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) are vacuum-deposited on an ITO layer (anode) formed on a glass substrate to form a hole injection layer having a thickness of 10 nm. At this time, compound B is doped so that the weight ratio of compound A and compound B is 98:2.
[0449] Afterwards, compound A is vacuum-deposited on the hole injection layer to form a hole transport layer with a thickness of 110 nm.
[0450] Afterwards, N is added to the 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.
[0451] Thereafter, a mixture host of the compound P-1 (first host) and the compound N-210 (second host) of the present invention 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 having a thickness of 30 nm. At this time, the dopant is doped so that the weight ratio of the host and the dopant becomes 95:5.
[0452] Afterwards, 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.
[0453] Afterwards, 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.
[0454] Afterwards, 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.
[0455] [Example 2] to [Example 28]
[0456] An organic light-emitting device was manufactured in the same manner as Example 1, except that the compounds described in Table 5 below were used as the first host and second host of the light-emitting layer.
[0457] [Comparative Example 1] to [Comparative Example 4]
[0458] An organic light-emitting device was manufactured in the same manner as in Example 1, except that one of Comparative Compounds A to D was used as the first host of the light-emitting layer.
[0459] Comparative Compound A <Comparative Compound B>

[0461] Comparative Compound C Comparative Compound D
[0462]
[0463] The organic electroluminescence devices manufactured by the examples and comparative examples of the present invention were subjected to a forward bias DC voltage and the electroluminescence (EL) characteristics were measured using a PR-650 from Photoresearch, and 2500 cd / m 2 T95 was measured using a life-span measuring device manufactured by Maxscience at a reference luminance. The measurement results are shown in Table 5 below.
[0464] These measuring devices are unaffected by daily variations in deposition rate, vacuum quality, or other parameters, and can evaluate new performance compared to reference compounds under identical conditions. Since each batch contains four identically prepared OLEDs containing the reference compound, and the performance of a total of 12 OLEDs is evaluated in three batches, the experimental results obtained in this manner are statistically significant.

[0466] From the above Table 5, it can be confirmed that when the material for an organic electroluminescent device of the present invention is used as a phosphorescent host material, the driving voltage, efficiency, and lifespan are significantly improved compared to when comparative compounds A to D are used. This shows that in the case of a mixed host, the characteristics of the device significantly vary depending on the type of compound combined.
[0467] Comparative compound A contains benzothiazole, whereas the compound of the present invention contains naphthoxazole or naphthothiazole, so there is a difference in the structure of the compounds.
[0468] Comparative Compound B differs in that the linker between the nitrogen of the naphthoxazole and the amino group is phenylene (arylene group), whereas the compound of the present invention is carbazole.
[0469] Comparative compounds C and D differ in that naphthoxazole is bonded to the nitrogen of the amine group via phenylene and a phenyl group (aryl group) is bonded to the nitrogen (N) of the carbazole, whereas the present invention is bonded to the nitrogen (N) of the carbazole via naphthoxazole or naphthothiazole.
[0470] These structural differences appear to affect the properties of the compounds, which in turn affect the performance of organic light-emitting devices when used as hosts.
[0471] To determine the influence of these structural differences on the device characteristics, the energy levels of comparative compounds A and B and compound P-9 of the present invention were measured using the DFT method (B3LYP / 6-31g(D)) of the Gaussian program. The measurement results are shown in Table 6 below.
[0472] Comparative Compound A Comparative Compound BP-9 HOMO (eV) -5.11-5.03-4.97
[0473] As can be seen in Table 6 above, the HOMO of the compound P-9 of the present invention is lower than that of the comparative compound A and the comparative compound B. Therefore, when the compound of the present invention is used as a host, not only can holes be transferred more smoothly from the light-emitting auxiliary layer to the host, but the hole transfer performance from the host to the dopant is also excellent, so that the efficiency of the device appears to be improved. Table 7 below shows the calculated weakest BDE (Bond Dissociation Energy) values of the comparative compounds A to D and the compound P-9 of the present invention. The weakest BDE is Schr The Bond and Ligand Dissociation panel using the Jaguar module of Dinger Materials Science (ver. 5.0.122, 2023-2) was utilized. In the present invention, optimization and BDE calculations were performed using the B3LYP method, which is a Becke, 3-parameter, Lee-Yang-Parr Method, and the 6-31G(d) basis set, one of the pople basis sets.

[0475] The BDE values presented in Table 7 above are the results measured in the oxidation state where intramolecular electrons are removed. A higher BDE value indicates greater structural stability. Therefore, the structural stability of the compound of the present invention is confirmed to be higher than that of comparative compounds, and as a result, the overall performance of the device, particularly efficiency and lifespan, appears to have been significantly improved.
