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.

[0035] 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.

[0036] 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.

[0037]

[0038] 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.

[0039] 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.

[0040]

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047]

[0048] Here, if a is an integer of 0, the substituent R 1means 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 1 It 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.

[0049]

[0050] 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.

[0051] 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.

[0052] 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.

[0053] ,

[0054] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] Figures 1 to 3 are exemplary diagrams of organic electric devices according to embodiments of the present invention.

[0062] 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).

[0063] 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.

[0064] 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.

[0065] 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).

[0066] 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.

[0067] 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).

[0068] 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.

[0069] 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.

[0070] 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).

[0071] 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.

[0072] 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.

[0073] 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).

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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).

[0078] 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.

[0079] 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).

[0080] 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.

[0081] 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.

[0082] An organic light emitting device 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 light emitting layer (140) and the electron transport layer (150), or may be formed in a stack structure as described above.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0299] In another aspect, the present invention provides an electronic device including a display device including an organic electric element and a control unit for driving the display device, wherein the organic electric element includes a compound represented by the above chemical formula 1 or contains compounds represented by the above chemical formula 1 and chemical formula I. Preferably, these compounds are included in a light-emitting layer, and more preferably, they are used as a host for the light-emitting layer.

[0300] The rearrangement energy of the compound used as a material of the light-emitting layer can affect the performance of the organic light-emitting device, and the rearrangement energy is explained below.

[0301] Reorganization energy (RE) refers to the energy lost due to changes in molecular structure during charge transfer (electrons and holes). It depends on molecular geometry and has the characteristic of decreasing as the difference between the neutral PES (Potential Energy Surface) and the charged PES decreases. The RE value can be calculated using the following formula.

[0302]

[0303] NONE: Neutral geometry of the molecule (= NO opt.)

[0304] NOAE: Anion geometry of neutral molecules

[0305] NOCE: Cation geometry of a neutral molecule

[0306] AONE: Neutral geometry of anion molecules

[0307] AOAE: Anion geometry of anion molecules (= AO opt.)

[0308] CONE: Neutral geometry of cation molecules

[0309] COCE: Cation geometry of the cation molecule (= CO opt.)

[0310] The rearrangement energy value and the mobility of charges are inversely proportional, and under the condition that they have the same r and T values, the RE value of each material directly affects the mobility.

[0311] The relationship between RE value and mobility is expressed as follows and is described by the charge transfer matrix element.

[0312]

[0313] (λ: Reorganization energy, μ: mobility, r: dimer displacement, t: intermolecular charge transfer matrix element)

[0314] According to the above equation, it can be seen that the smaller the RE value, the faster the mobility of charges.

[0315] To obtain rearrangement energy values, a simulation tool capable of calculating potential energy based on molecular structure is required. For example, Gaussian09 (G09) and Schrödinger Materials Science's Jaguar (JG) modules can be used. Both G09 and JG analyze molecular properties through quantum mechanical (QM) calculations and offer the ability to optimize molecular structures or calculate single-point energy for a given molecular structure.

[0316] Performing QM calculations on molecular structures requires significant computational resources. For example, two cluster servers could be used for these calculations. Each cluster server consists of four node workstations and one master workstation, with each node using CPUs with 36 or more cores, enabling molecular QM calculations through parallel computing via symmetric multiprocessing (SMP).

[0317] Using G09, we calculate the molecular structures optimized for neutral / charge states and their potential energies (NONE / COCE) required for rearrangement energy. By changing only the charges of the two optimized structures, we calculate the charge-state potential energy (NOCE) of the structure optimized for the neutral state and the neutral-state potential energy (CONE) of the structure optimized for the charge state. Then, we calculate the rearrangement energy according to the following equation.

[0318]

[0319] Since Schrödinger provides a function to automatically perform this calculation process, the JG module can sequentially calculate the potential energy for each state and calculate the RE value simply by providing the molecular structure (NO) of the basic state.

[0320] The RE value of chemical formula 1 calculated in this manner may preferably be 0.100 to 0.200, and more preferably 0.120 to 0.170.

[0321] In another aspect, the present invention provides a compound represented by the chemical formula 1 obtained by recovering and purifying the material of an organic layer from a deposition device after depositing the organic layer in a manufacturing process of an organic electric device. The purity of the compound obtained by recovery and purification is 99.9% or higher.

[0322] In another aspect, the present invention provides a method for recovering a compound, comprising the steps of depositing an organic layer material including a compound represented by Chemical Formula 1, recovering the organic layer material attached to a deposition device, and purifying the recovered organic layer material to obtain a compound represented by Chemical Formula 1 having a purity of 99.9% or higher.

[0323] The above purification step may include a step of recrystallizing the recovered organic layer material using a recrystallization solvent, a step of adsorption separation using an adsorbent, and a step of sublimation purification.

[0324] The above recrystallization step may include a preliminary purification process for obtaining a compound represented by the above chemical formula 1 with a purity of 98% using a recrystallization solvent.

[0325] A polar solvent having a polarity index (PI) of 5.5 to 7.2 is preferably used as the recrystallization solvent, or a mixture of a polar solvent having a polarity index of 5.5 to 7.2 and a non-polar solvent having a polarity index of 2.0 to 4.7 may be used.

[0326] When using a mixture of a polar solvent and a non-polar solvent as a recrystallization solvent, the non-polar solvent may be used in a ratio of 15% (v / v) or less compared to the polar solvent.

[0327] In addition, as a recrystallization solvent, a single solvent of methylpyrrolidone (N-methylpyrrolidone: NMP) is preferably used; or a mixed polar solvent in which any one selected from the group consisting of methylpyrrolidone, dimethyl imidazolidinone (1,3-dimethyl-2-imidazolidinone), 2-pyrrolidone, dimethylformamide (N,N-dimethyl formamide), dimethyl acetamide, and dimethyl sulfoxide is mixed; or a single or mixed nonpolar solvent selected from the group consisting of toluene, dichloromethane (DCM), dichloroethane (DCE), tetrahydrofuran (THF), chloroform, ethyl acetate, and butanone, or a mixture of polar solvents and nonpolar solvents can be used.

[0328] The above preliminary purification process may include a step of dissolving the unrefined organic light-emitting material recovered from the deposition equipment in a polar solvent at 90°C to 120°C and then cooling it to 0°C to 5°C to precipitate crystals.

[0329] The above preliminary purification process may include a step of dissolving an unrefined organic light-emitting material recovered from a deposition device in a polar solvent at 90°C to 120°C, cooling to 35°C to 40°C, adding a non-polar solvent, and then cooling to 0°C to 5°C to precipitate a crystal.

[0330] The above preliminary purification process may include a step of dissolving the crude organic light-emitting material recovered from the deposition equipment in a non-polar solvent, concentrating the solvent, and precipitating crystals while removing the non-polar solvent.

[0331] The above preliminary purification process may include a step of first recrystallizing with a polar solvent and then recrystallizing again with a non-polar solvent.

[0332] In the adsorption separation step using the above adsorbent, activated carbon, silica gel, alumina or a known material for adsorption purposes can be used as the adsorbent.

[0451] 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.

[0452] Manufacturing and evaluation of organic electronic devices

[0453] [Example 1] Red organic light-emitting device (phosphorescent host)

[0454] 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.

[0455] Afterwards, compound A is vacuum-deposited on the hole injection layer to form a hole transport layer with a thickness of 110 nm.

[0456] 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.

[0457] Thereafter, a mixture host of the compound P-1 (first host) and the compound N-8 (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.

[0458] 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.

[0459] 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.

[0460] 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.

[0461] [Example 2] to [Example 32]

[0462] 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.

[0463] [Comparative Example 1] and [Comparative Example 2]

[0464] An organic light-emitting device was manufactured in the same manner as in Example 1, except that Comparative Compound A or Comparative Compound B was used as the first host of the light-emitting layer.

[0465] Comparative Compound A <Comparative Compound B>

[0466]

[0467] The organic electroluminescence devices manufactured by Examples 1 to 32 of the present invention and Comparative Examples 1 and 2 were subjected to a forward bias DC voltage, and the electroluminescence (EL) characteristics were measured using 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.

[0468] 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.

[0470] From the above Table 5, it can be seen that when the compound of the present invention is used as a host for the light-emitting layer, the operating voltage of the organic light-emitting device is significantly lowered and the efficiency and lifespan are significantly improved compared to when Comparative Compound A or Comparative Compound B is used. Comparative Compound A and Comparative Compound B are similar to the compound of the present invention in that an amine is substituted at the 2nd position of dibenzothiophene and a 4-condensed ring is substituted at the 9th position. However, Comparative Compound A differs from the compound of the present invention in that the 4-condensed ring is benzocarbazole, and Comparative Compound B differs from the compound of the present invention in the substitution position of the 4-condensed ring.

[0471] In order to examine the influence of these structural differences on the rearrangement energy of compounds, the rearrangement energies of comparative compounds A and B and the compound P-161 of the present invention having a similar structure to them were measured using the DFT method (B3LYP / 6-31g(D)) of the Gaussian program. The measurement results are as shown in Table 6 below, and the RE value is RE hole Indicates a value.

[0472] Compound Reorganization Energy (RE) P-1610.135 Comparative Compound A0.161 Comparative Compound B0.138

[0473] From the above Table 6, it can be seen that the RE value of the compound P-161 of the present invention, which has a structure similar to that of the comparative compound, is measured to be the lowest. Therefore, the compound of the present invention with a low RE value has higher mobility and faster HOD (Hole on Device) than the comparative compounds A and B, and thus has significantly superior hole transport and hole injection, and as a result, the driving voltage is reduced and the hole injection of the dopant increases as the hole is enriched in the emitting layer, which improves the roll-off and significantly improves the efficiency and lifespan. Next, in order to confirm the degree of π-π stacking according to the substituent substituted at the 9th position of dibenzofuran or dibenzothiophene, the molecular structures of the comparative compounds A and B and the compound P-161 of the present invention were confirmed using molecular simulation (Schrodinger Materials Science Suite 4.9.128).

[0474] Figures 4 to 6 show optimized structural formulas of compound P-161 of the present invention, comparative compound A, and comparative compound B, respectively, using a molecular simulation program. In Figures 4 to 6, dotted lines represent π-π stacking.

[0475] Looking at Figures 4 to 6, it can be seen that the configuration of the molecule changes depending on the type of substituent substituted at position 9 of dibenzofuran or dibenzothiophene.

[0476] The π-π stacking of compound P-161 of the present invention is a 4-condensed ring substituted at position 9 of dibenzofuran and Ar 1 or Ar 2 π-π stacking occurs through the faces of the moieties, and each π-π stacking is also parallel, allowing for smooth charge transfer within the molecule.

[0477] On the other hand, in the case of comparative compound A, although π-π stacking exists, the structure is distorted due to the substituent at the 7th position of benzocarbazole, so the π-π stacking is very weak and the two π-π stackings in the molecule are staggered, so the effect due to π-π stacking is practically minimal. In addition, in the case of comparative compound B, it can be confirmed that π-π stacking does not occur at all in the molecule because the substitution position of the 4-condensed ring is different from that of the compound of the present invention.

[0478] Therefore, when the compound of the present invention is used as a light-emitting layer material, the transfer of intramolecular charges is smooth, so that charge balance within the light-emitting layer is well achieved, and it appears that the operation, efficiency, and lifespan of the device are improved.

[0479] From the above Tables 5 and 6, it can be confirmed that the compound of the present invention, which satisfies all complex factors such as the type of substituent and the substitution position of the substituent, exhibits a remarkable effect in an organic electric device compared to other comparative compounds, even though the compound has a similar structure. Through this, it can be seen that the compound of the present invention exhibits a remarkable effect in an organic electric device compared to other compounds having a similar structure not described in the present specification.

[0480] Through this, it can be seen that even when compounds with similar structures are used as hosts, the properties of the compound, such as hole characteristics, light efficiency characteristics, energy level, hole injection and mobility characteristics, charge balance of holes and electrons, volume density, and intermolecular distance, can differ depending on the type of substituent, the substitution position of the substituent, etc., and the performance of the device can differ significantly due to these differences.

[0481] The above description is merely illustrative of the present invention. Those skilled in the art will appreciate that various modifications may be made without departing from the essential characteristics of the present invention. The scope of protection of the present invention should be construed in accordance with the claims below, and all techniques within the scope equivalent thereto should be construed as being included within the scope of the present invention.
