Abstract
Description
Heterocyclic compound, organic light-emitting device and composition for organic layer of organic light-emitting device
[0001] The present specification relates to a heterocyclic compound, an organic light-emitting device, and a composition for an organic layer of an organic light-emitting device.
[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0189779, filed with the Korean Intellectual Property Office on December 22, 2023, the entire contents of which are incorporated herein by reference.
[0003] Electroluminescent elements are a type of self-luminous display element that have the advantages of a wide viewing angle, excellent contrast, and a fast response speed.
[0004] Organic light-emitting devices have a structure in which an organic thin film is placed between two electrodes. When voltage is applied to an organic light-emitting device of this structure, electrons and holes injected from the two electrodes combine in the organic thin film, forming pairs and then disappearing, emitting light. The organic thin film may be composed of a single layer or multiple layers, as needed.
[0005] The material of the organic thin film may have a light-emitting function as needed. For example, the organic thin film material may be a compound that can form a light-emitting layer on its own, or a compound that can act as a host or dopant in a host-dopant light-emitting layer. In addition, the material of the organic thin film may be a compound that can perform roles such as hole injection, hole transport, electron blocking, hole blocking, electron transport, and electron injection.
[0006] To improve the performance, lifespan, or efficiency of organic light-emitting devices, the development of materials for organic thin films is continuously required.

[0008] (Patent Document 1) U.S. Patent No. 4,356,429
[0009] The present specification provides a heterocyclic compound and an organic light-emitting device including the same, and a composition for an organic layer of the organic light-emitting device, thereby providing an organic light-emitting device having a low driving voltage and high luminous efficiency and lifespan.
[0010] In one embodiment of the present specification, a heterocyclic compound of the following chemical formula 1 is provided.
[0011] [Chemical Formula 1]
[0012]
[0013] In the above chemical formula 1,
[0014] Y is O or S,
[0015] X1 to X3 are each independently N or CH, and at least one is N,
[0016] Ar1 and Ar2 are each independently a C6 to C60 aryl group; or a C2 to C60 heteroaryl group,
[0017] L is an arylene group of C10 to C30 substituted with deuterium, m is an integer of 1 to 3, and when it is 2 or more, L is the same or different,
[0018] R1 to R8 are each independently hydrogen; deuterium; a substituted or unsubstituted C1 to C60 alkyl group; a substituted or unsubstituted C3 to C60 cycloalkyl group; a substituted or unsubstituted C2 to C60 heterocycloalkyl group; a substituted or unsubstituted C6 to C60 aryl group; or a substituted or unsubstituted C2 to C60 heteroaryl group, or adjacent groups are bonded to each other to form a ring.
[0019] At least one of R1 to R8 is deuterium,
[0020] D is deuterium, and n is an integer from 0 to 6.
[0021] In another embodiment of the present specification, an organic light-emitting device is provided, comprising: a first electrode; a second electrode; and at least one organic layer provided between the first electrode and the second electrode, wherein at least one of the organic layers includes at least one type of the heterocyclic compound.
[0022] In another embodiment of the present specification, a composition for an organic layer of an organic light-emitting device comprising the heterocyclic compound is provided.
[0023] The heterocyclic compound described herein, when used in an organic light-emitting device, can lower the driving voltage of the device, improve the luminous efficiency, and improve the lifespan characteristics of the device. Specifically, the heterocyclic compound of the present invention is characterized in that it includes dibenzofuran or dibenzothiophene as a core structure as in Chemical Formula 1, an azine group is substituted without a linker as one substituent, and a carbazole group is included as another substituent, but a linker is necessarily included between the core structure and the carbazole group, and the carbazole group and the linker include at least one deuterium, whereas the azine group does not include deuterium.
[0024] As in the heterocyclic compound of the present invention, since deuterium is substituted only at specific positions, the vibrational energy of the HOMO region, which requires hole stability, is reduced, which reduces intermolecular interactions and exhibits excellent lifetime characteristics within the device. In addition, since the azine group does not include a linker and the carbazole group includes a linker, the HOMO region is expanded, thereby synthesizing a compound with a more stable HOMO. The expansion of the HOMO not only ensures molecular stability but also induces smooth charge transfer, which can exhibit excellent efficiency and lifetime characteristics within the device.

[0037] Hereinafter, the present specification will be described in more detail.
[0038] In this specification, when a part is said to "include" a component, this does not mean that it excludes other components, but rather that it may include other components, unless specifically stated otherwise.
[0039] In this specification, “N to N'” means N or more and N' or less.
[0040] In this specification, the chemical formula means the position where it is combined.
[0041] The term "substitution" above means that a hydrogen atom bonded to a carbon atom or nitrogen atom of a compound is replaced with another substituent, and the position of substitution is not limited as long as it is a position where a hydrogen atom is replaced, i.e. a position where a substituent can be replaced, and when two or more are replaced, the two or more substituents may be the same or different from each other.
[0042] In this specification, "substituted or unsubstituted" means substituted or unsubstituted with one or more substituents selected from the group consisting of deuterium; a halogen group; a cyano group; a C1 to C60 alkyl group; a C2 to C60 alkenyl group; a C2 to C60 alkynyl group; a C1 to C60 alkoxy group; a C6 to C60 aryloxy group; a C1 to C60 alkylthioxy group; a C6 to C60 arylthioxy group; a C1 to C60 alkylsulfoxy group; a C6 to C60 arylsulfoxy group; a C3 to C60 cycloalkyl group; a C2 to C60 heterocycloalkyl group; a C6 to C60 aryl group; a C2 to C60 heteroaryl group; a silyl group; a phosphine oxide group; and an amine group, or a substituent in which two or more substituents selected from the above substituents are linked, or unsubstituted.
[0043] In this specification, "when no substituent is indicated in the chemical formula or compound structure" means that a hydrogen atom is bonded to a carbon atom. However, deuterium ( 2 H, Deuterium) is an isotope of hydrogen, so some hydrogen atoms may be deuterium.
[0044] In one embodiment of the present application, "when no substituent is indicated in the chemical formula or compound structure" may mean that all positions that can be substituted are hydrogen or deuterium. That is, in the case of deuterium, it is an isotope of hydrogen, and some hydrogen atoms may be the isotope deuterium, in which case the deuterium content may be 0% to 100%, and the deuterium content may also be expressed as a deuterium substitution ratio.
[0045] In one embodiment of the present application, deuterium is an element having a deuteron, which is one of the isotopes of hydrogen and is composed of one proton and one neutron, as its nucleus, and can be expressed as hydrogen-2, and its element symbol is D or 2 It can also be written as H.
[0046] In one embodiment of the present application, an isotope means an atom having the same atomic number (Z) but a different mass number (A). An isotope can also be interpreted as an element having the same number of protons but a different number of neutrons.
[0047] In one embodiment of the present application, the meaning of the substitution rate T% of a specific substituent can be defined as T2 / T1Х100 = T%, where the total number of substituents that the basic compound can have is defined as T1, and the number of specific substituents among them is defined as T2.
[0048] That is, in one example, In the phenyl group represented by , a deuterium substitution rate of 20% means that the total number of substituents that the phenyl group can have is 5 (T1 in the formula), and if the number of deuteriums among them is 1 (T2 in the formula), it can be expressed as 20%. In other words, a deuterium substitution rate of 20% in the phenyl group can be expressed by the structural formula below.
[0049]
[0050] Additionally, in one embodiment of the present application, the term "phenyl group having a deuterium substitution rate of 0%" may mean a phenyl group that does not contain a deuterium atom as a substituent, i.e., has 5 hydrogen atoms.

[0182] In one embodiment of the present specification, the D4 may be a group represented by the chemical formula B, and the D2 may be a group represented by the chemical formula C.
[0183] In one embodiment of the present specification, the D4 may be a group represented by the chemical formula B, and the D3 may be a group represented by the chemical formula C.
[0184] In one embodiment of the present specification, the D4 may be a group represented by the chemical formula B, and the D5 may be a group represented by the chemical formula C.

[0187] In one embodiment of the present specification, the D4 may be a group represented by the chemical formula B, and the D8 may be a group represented by the chemical formula C.
[0188] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula A is 0% to 100%, the deuterium substitution rate of the chemical formula B is 0%, and the deuterium substitution rate of the chemical formula C may be greater than 0% and less than or equal to 100%.
[0189] In this specification, the deuterium substitution rate of the chemical formulas A to C refers to the substitution rate of deuterium with respect to the total number of hydrogens and deuteriums contained in the chemical formulas A to C, respectively.
[0190] That is, the chemical formula B does not contain deuterium at all, and the chemical formula C necessarily contains deuterium.
[0191] With the core structure, chemical formula A, as the center, one substituent contains deuterium and the other does not, thereby maximizing the effects of deuterium substitution and efficiently obtaining a compound through a synthetic method. The azine group, which exhibits electronic properties, not only has a minimal long-life effect due to deuterium substitution, but also reduces the stacking effect, resulting in a decrease in carrier mobility, which can result in an increase in operating voltage.
[0192] In general, compounds substituted with only hydrogen and compounds substituted with deuterium show differences in thermodynamic behavior due to differences in atomic mass, van der Waals radius, etc. Deuterium has lower vibrational energy than hydrogen, and the bond between carbon and deuterium is shorter and has stronger dissociation energy compared to the bond between carbon and hydrogen. Accordingly, compounds substituted with deuterium have the characteristic of having a lower ground state energy than compounds substituted with only hydrogen, and the molecular hardcore volume is reduced, which can reduce electrical polarizability. In addition, it has the effect of increasing the volume of the device thin film by weakening the intermolecular interaction, and lowering the crystallinity by creating an amorphous state of the thin film. Therefore, when the heterocyclic compound of the present invention is used as a material for an OLED device, the device efficiency and lifespan characteristics can be improved.
[0193] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula A is 0%, the deuterium substitution rate of the chemical formula B is 0%, and the deuterium substitution rate of the chemical formula C may be greater than 0% and less than or equal to 100%.
[0194] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula A may be greater than 0% and less than or equal to 100%, the deuterium substitution rate of the chemical formula B may be greater than 0% and less than or equal to 100%, and the deuterium substitution rate of the chemical formula C may be greater than 0% and less than or equal to 100%.
[0195] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula C may be 10% to 100%.
[0196] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula C may be 30% to 100%.
[0197] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula C may be 50% to 100%.
[0198] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; a substituted or unsubstituted C1 to C30 alkyl group; a substituted or unsubstituted C3 to C30 cycloalkyl group; a substituted or unsubstituted C2 to C30 heterocycloalkyl group; a substituted or unsubstituted C6 to C30 aryl group; or a substituted or unsubstituted C2 to C30 heteroaryl group, or adjacent groups may be bonded to each other to form a ring, and at least one of R1 to R8 is deuterium.
[0199] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; a substituted or unsubstituted C1 to C10 alkyl group; a substituted or unsubstituted C3 to C20 cycloalkyl group; a substituted or unsubstituted C2 to C20 heterocycloalkyl group; a substituted or unsubstituted C6 to C20 aryl group; or a substituted or unsubstituted C2 to C20 heteroaryl group, or adjacent groups may be bonded to each other to form a ring, and at least one of R1 to R8 is deuterium.
[0200] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; a substituted or unsubstituted C1 to C30 alkyl group; a substituted or unsubstituted C3 to C30 cycloalkyl group; a substituted or unsubstituted C2 to C30 heterocycloalkyl group; a substituted or unsubstituted C6 to C30 aryl group; or a substituted or unsubstituted C2 to C30 heteroaryl group, and at least one of R1 to R8 is deuterium.
[0201] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; a substituted or unsubstituted C1 to C10 alkyl group; a substituted or unsubstituted C3 to C20 cycloalkyl group; a substituted or unsubstituted C2 to C20 heterocycloalkyl group; a substituted or unsubstituted C6 to C20 aryl group; or a substituted or unsubstituted C2 to C20 heteroaryl group, and at least one of R1 to R8 is deuterium.
[0202] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; or a substituted or unsubstituted C6 to C30 aryl group, and at least one of R1 to R8 is deuterium.
[0203] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; or a substituted or unsubstituted C6 to C20 aryl group, and at least one of R1 to R8 is deuterium.
[0204] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; or a C6 to C30 aryl group substituted or unsubstituted with deuterium, and at least one of R1 to R8 is deuterium.
[0205] In one embodiment of the present specification, R1 to R8 are each independently hydrogen; deuterium; or a C6 to C20 aryl group substituted or unsubstituted with deuterium, and at least one of R1 to R8 is deuterium.
[0206] In one embodiment of the present specification, D is deuterium, and n is an integer from 0 to 6.
[0207] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula 1 may be from more than 0% to 90%.
[0208] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula 1 may be 10% to 90%.
[0209] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula 1 may be 20% to 90%.
[0210] In one embodiment of the present specification, the deuterium substitution rate of the chemical formula 1 may be 30% to 80%.
[0211] In this specification, the deuterium substitution rate of the chemical formula 1 refers to the substitution rate of deuterium with respect to the total number of hydrogens and deuteriums contained in the chemical formula 1. For example, if there are 20 hydrogens and 20 deuteriums contained in the chemical formula 1, the substitution rate of 20 deuteriums with respect to the total of 40 hydrogens and deuteriums is 50%.
[0212] In one embodiment of the present specification, when the deuterium substitution rate of the heterocyclic compound of the chemical formula 1 satisfies the above range, the photochemical characteristics of the compound not containing deuterium and the compound containing deuterium are almost similar, but when deposited on a thin film, the material containing deuterium tends to be packed with a narrower intermolecular distance.
[0213] Accordingly, by fabricating an EOD (Electron Only Device) and a HOD (Hole Only Device) and checking the current density according to the voltage, it can be confirmed that the heterocyclic compound of chemical formula 1 of the present invention exhibits much more balanced charge transport characteristics than a compound that does not contain deuterium.
[0214] Additionally, when looking at the surface of the thin film with an atomic force microscope (AFM), it can be confirmed that the thin film made of a compound containing deuterium is deposited with a more uniform surface without any aggregated areas.
[0215] Additionally, since the single bond dissociation energy of carbon and deuterium is higher than the single bond dissociation energy of carbon and hydrogen, in the case of the heterocyclic compound of chemical formula 1 of the present invention, the stability of the entire molecule increases, thereby improving the device lifespan.
[0216] In one embodiment of the present specification, the chemical formula 1 may be represented by any one of the following compounds.

[0244] The deuterium substitution rate can be determined from the number of deuterium atoms indicated in the above compound, and the substitution positions may be slightly different.
[0245] That is, when only a portion of the linker or carbazole structure is substituted with deuterium, deuterium is marked at an arbitrary position to indicate the deuterium substitution ratio, and the deuterium substitution position may vary depending on the synthesis.
[0246] In addition, by introducing various substituents into the structure of the above chemical formula 1, compounds having the unique characteristics of the introduced substituents can be synthesized. For example, by introducing substituents mainly used in hole injection layer materials, hole transport layer materials, light-emitting layer materials, electron transport layer materials, and charge generation layer materials used in the manufacture of organic light-emitting devices into the core structure, a material satisfying the conditions required for each organic layer can be synthesized.

However, the scope of the present application is not intended to be limited by these drawings, and the structure of an organic light-emitting device known in the art may also be applied to the present application.
[0331] According to FIG. 1, an organic light-emitting device is illustrated in which an anode (200), an organic layer (300), and a cathode (400) are sequentially laminated on a substrate (100). However, the present invention is not limited to this structure, and an organic light-emitting device in which a cathode, an organic layer, and an anode are sequentially laminated on a substrate, as shown in FIG. 2, may also be implemented.

[0340] For example, LiF is a representative material used in the art, but the present application is not limited thereto.
[0341] Red, green, or blue light-emitting materials may be used as the light-emitting material, and if necessary, two or more light-emitting materials may be mixed and used. At this time, two or more light-emitting materials may be deposited and used as individual sources, or may be premixed and deposited and used as a single source. In addition, a fluorescent material may be used as the light-emitting material, but it may also be used as a phosphorescent material. A material that emits light by combining holes and electrons injected from the anode and cathode, respectively, may be used as the light-emitting material, but materials in which both the host material and the dopant material participate in light emission may also be used.
[0342] When using a mixture of hosts for light-emitting materials, hosts of the same series may be mixed and used, or hosts of different series may be mixed and used. For example, two or more types of materials, either N-type host materials or P-type host materials, may be selected and used as the host materials for the light-emitting layer.
[0343] An organic light-emitting device according to one embodiment of the present specification may be a front-emitting, back-emitting, or double-sided emitting device depending on the material used.
[0344] The heterocyclic compound according to one embodiment of the present specification can function in organic electronic devices, including organic solar cells, organic photoconductors, organic transistors, etc., by a similar principle to that applied to organic light-emitting devices.
[0345] In addition, by introducing various substituents into the structure of the above chemical formula 1, it is possible to finely control the energy band gap, while improving the properties at the interface between organic substances and diversifying the uses of the material.
[0346] Another embodiment of the present specification provides a composition for an organic layer comprising the heterocyclic compound.
[0347] In one embodiment of the present specification, the composition for the organic layer may further include a compound of the chemical formula 2.
[0348] In one embodiment of the present specification, the composition for the organic layer may include the heterocyclic compound and the compound of the chemical formula 2 in a weight ratio of 1:10 to 10:1.
[0349] In one embodiment of the present specification, the composition for the organic layer may include the heterocyclic compound and the compound of the chemical formula 2 in a weight ratio of 1:8 to 8:1, 1:5 to 5:1, or 1:3 to 3:1.
[0350] In one embodiment of the present specification, the composition for the organic layer may include the heterocyclic compound and the compound of the chemical formula 2 in a weight ratio of 1:1 to 5:1, or 1:1 to 3:1.
[0351] Another embodiment of the present specification provides a method for manufacturing an organic light-emitting device, comprising the steps of: preparing a substrate; forming a first electrode on the substrate; forming one or more organic layers on the first electrode; and forming a second electrode on the organic layer, wherein the step of forming the organic layer includes the step of forming one or more organic layers using the organic layer composition described above.
[0352] In one embodiment of the present specification, the step of forming the organic layer may include a step of premixing a composition for the organic layer of the organic light-emitting device and depositing it using one supply source.
[0353] The above pre-mixing means that the heterocyclic compound of the above chemical formula 1 and the compound of the above chemical formula 2 are mixed in one container before being deposited on the organic layer. In the case of pre-mixing, there is an advantage in that the process is simpler because one deposition source is used instead of two or more deposition sources.
[0354] When premixing the composition for the above organic layer, the inherent thermal properties of each material can significantly affect deposition conditions, such as the deposition rate, when depositing the premixed material. Therefore, the inherent thermal properties of each material to be premixed must be confirmed. If the thermal properties of the materials are not similar, repeatability and reproducibility in the deposition process cannot be maintained, and uniform OLED devices cannot be manufactured.
[0355] To overcome this, the electrical properties of each material can be tuned by appropriately combining the basic structure and substituents of each material, while thermal properties can also be controlled based on the morphology of the molecular structure. By manipulating the thermal properties of each material, a variety of host-to-host premixed deposition processes can be secured. This allows for the creation of diverse premixed deposition processes utilizing not only two compounds as hosts, but also three or more host materials.
[0356] In one embodiment of the present specification, the composition for the organic layer may include a host other than the compound of the chemical formula 2.
[0357] In one embodiment of the present specification, the composition for the organic layer includes the compound of the chemical formula 2 and may further include another host.
[0358] Hereinafter, the present specification will be described in more detail through examples, but these are only intended to illustrate the present application and are not intended to limit the scope of the present application.

[0418] Experimental Example 1
[0419] (1) Fabrication of organic light-emitting devices
[0420] A glass substrate coated with a 1,500 Å thick ITO film was ultrasonically cleaned in distilled water. After the distilled water cleaning, it was ultrasonically cleaned with solvents such as acetone, methanol, and isopropyl alcohol, dried, and then treated with UVO for 5 minutes in a UV cleaner. The substrate was then transferred to a plasma cleaner (PT), where it was plasma-treated in a vacuum to remove the ITO work function and residual film, and then transferred to a thermal evaporation equipment for organic deposition.
[0421] A common layer, a hole injection layer 2-TNATA (4,4′,4′′-Tris[2-naphthyl (phenyl)amino]triphenylamine) and a hole transport layer NPB (N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine), were formed on the ITO transparent electrode (anode).
[0422] On top of that, a light-emitting layer was thermally vacuum deposited as follows. The light-emitting layer used the compounds listed in Table 9 as a host, and Ir(mppy)3Tris[2-(p-tolyl)pyridine]iridium(III) as a green phosphorescent dopant. The host was doped with 7% Ir(mppy)3 and deposited to a thickness of 360Å. Then, BCP was deposited to a thickness of 60Å as a hole-blocking layer, and Alq3 was deposited to a thickness of 200Å as an electron-transporting layer thereon. Finally, lithium fluoride (LiF) was deposited to a thickness of 10Å on the electron-transporting layer to form an electron injection layer, and then an aluminum (Al) cathode was deposited to a thickness of 1200Å on the electron injection layer to form a cathode, thereby manufacturing an organic electroluminescent device.
[0423] Meanwhile, all organic compounds required for OLED device production are 10 for each material. -8 ~10 -6 It was purified by vacuum sublimation under 10 torr and used in OLED production.
[0424] The structures of the compounds used in Comparative Examples 1 to 7 are as follows.

[0426] 2) Driving voltage and luminous efficiency of organic field effect devices
[0427] The electroluminescence (EL) characteristics of the organic electroluminescent device manufactured as described above were measured using M7000 from Max Science, and the standard luminance was determined to be 6,000 cd / m using the life measurement equipment (M6000) manufactured by Max Science based on the measurement results. 2 At that time, T90 was measured.
[0428] The results of measuring the driving voltage, luminous efficiency, color coordinates (CIE), and lifespan of the organic light-emitting device manufactured according to the present invention are as shown in Table 9 below.

[0430] Looking at the results in Table 9 above, it can be seen that the driving voltage of the examples using the heterocyclic compound according to the present invention is lower, the luminous efficiency is higher, and the lifespan is significantly improved compared to Comparative Examples 1 to 7.
[0431] This is because deuterium is heavier than light hydrogen and has lower vibrational energy, so compounds substituted with deuterium show higher lifetime characteristics in devices than compounds that are not substituted. This effect is maximized in the case of the hole transfer unit, and the effect is minimal in the electron transfer unit. This is expected to be because holes have lower stability than electrons due to the vibrational energy of molecules and intermolecular interactions. Therefore, it can be seen that the compound of Comparative Example 2 (Ref. 2), in which the deuterium substitution range is less than that of the compound of the present invention and deuterium is substituted in the trizaine region, which is the electron transfer unit, shows lower characteristics in devices than the compound of the present invention.
[0432] In addition, the expansion of the linker between dibenzofuran / dibenzothiophene and carbazole delocalizes the HOMO electron cloud, thereby stabilizing the HOMO region and facilitating charge transfer. Therefore, the compounds of the present invention exhibited superior device performance compared to compounds without a linker between dibenzofuran / dibenzothiophene and carbazole. Specifically, Ref. 7 used in Comparative Example 7 did not contain a linker compared to Compound 10 used in Example 1, and it was confirmed that the driving voltage increased, the luminous efficiency decreased, and the lifespan was reduced by about 50% compared to Example 1.
[0433] In addition, Ref. 1 used in Comparative Example 1 does not include deuterium in the linker and carbazole structure, and Ref. 2 used in Comparative Example 2 not only does not include deuterium in the carbazole structure, but also includes deuterium in the azine group. In addition, Ref. 3 of Comparative Example 3 does not include deuterium in the linker, and Ref. 4 and Ref. 5 used in Comparative Examples 4 and 5 do not satisfy the deuterium feature of the present invention as well as the linker configuration between the core structure and the carbazole group. Finally, Ref. 6 of Comparative Example 6 differs from the present invention in that it includes a linker between the azine group and the core structure as well as the deuterium feature of the present invention.
[0434] That is, when an organic light-emitting device is manufactured using a compound that does not satisfy all the configurations of the present invention, it cannot provide excellent performance in terms of driving voltage, luminous efficiency, and lifespan, whereas it was confirmed that an organic light-emitting device manufactured using the heterocyclic compound of the present invention obtains significantly improved performance.

Afterwards, the substrate was transferred to a plasma cleaner (PT), where it was plasma-treated in a vacuum to remove the ITO work function and residual film, and then transferred to a thermal evaporation equipment for organic deposition.
[0439] A common layer, a hole injection layer 2-TNATA (4,4′,4′′-Tris[2-naphthyl (phenyl)amino]triphenylamine) and a hole transport layer NPB (N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine), were formed on the ITO transparent electrode (anode).
[0440] On top of that, a light-emitting layer was thermally vacuum deposited as follows. The light-emitting layer was pre-mixed with one heterocyclic compound of Chemical Formula 1 and one compound of Chemical Formula 2, as shown in Table 10 below, as a host, and then deposited at 360Å in one hole, and the green phosphorescent dopant was doped with Ir(mppy)3 at 7% of the thickness of the light-emitting layer deposition and deposited. After that, 60Å of BCP was deposited as a hole-blocking layer, and 200Å of Alq3 was deposited as an electron-transporting layer thereon. Finally, lithium fluoride (LiF) was deposited with a thickness of 10Å on the electron-transporting layer to form an electron injection layer, and then an aluminum (Al) cathode was deposited with a thickness of 1,200Å on the electron injection layer to form a cathode, thereby manufacturing an organic electroluminescent device.

[0446] Comparing the results of Tables 9 and 10 above, it was confirmed that when the heterocyclic compound of the present invention was used alone, the driving voltage, luminous efficiency, and lifespan were all significantly improved when the compound of Chemical Formula 2 was used in combination.
[0447] From the above results, it can be expected that an exciplex phenomenon will occur when the heterocyclic compound of chemical formula 1 and the compound of chemical formula 2 are simultaneously included.
[0448] The exciplex phenomenon is a phenomenon in which energy is released in the size of the HOMO energy level of the donor (p-host) and the LUMO energy level of the acceptor (n-host) due to the exchange of electrons between two molecules. When the exciplex phenomenon occurs between two molecules, reverse intersystem crossing (RISC) occurs, and this can increase the internal quantum efficiency of fluorescence emission to 100%.
[0449] When a donor (p-host) with good hole transport capability and an acceptor (n-host) with good electron transport capability are used as hosts for the light-emitting layer, holes are injected into the p-host and electrons are injected into the n-host. At this time, excitons are not quenched due to intermolecular electron exchange, and the lifetime of excitons that can have energy increases. As a result, the overall current efficiency is improved and the lifespan of the device can be improved. In the present invention, it was confirmed that when the compound of the above chemical formula 1 acts as an acceptor and the compound of the above chemical formula 2 acts as a donor and they are used together as a host for the light-emitting layer, excellent device characteristics are exhibited.
