Title: Heterocyclic compound and organic light-emitting device comprising same

Description:
TECHNICAL FIELD 
     The present specification relates to a heterocyclic compound, and an organic light emitting device including the same. 
     This application claims priority to and the benefits of Korean Patent Application No. 10-2019-0119670, filed with the Korean Intellectual Property Office on Sep. 27, 2019, the entire contents of which are incorporated herein by reference. 
     BACKGROUND ART 
     An electroluminescent device is one type of self-emissive display devices, and has an advantage of having a wide viewing angle, and a high response speed as well as having an excellent contrast. 
     An organic light emitting device has a structure disposing an organic thin film between two electrodes. When a voltage is applied to an organic light emitting device having such a structure, electrons and holes injected from the two electrodes bind and pair in the organic thin film, and light emits as these annihilate. The organic thin film may be formed in a single layer or a multilayer as necessary. 
     A material of the organic thin film may have a light emitting function as necessary. For example, as a material of the organic thin film, compounds capable of forming a light emitting layer themselves alone may be used, or compounds capable of performing a role of a host or a dopant of a host-dopant-based light emitting layer may also be used. In addition thereto, compounds capable of performing roles of hole injection, hole transfer, electron blocking, hole blocking, electron transfer, electron injection and the like may also be used as a material of the organic thin film. 
     Development of an organic thin film material has been continuously required for enhancing performance, lifetime or efficiency of an organic light emitting device. 
     DISCLOSURE 
     Technical Problem 
     The present specification is directed to providing a heterocyclic compound, and an organic light emitting device including the same. 
     Technical Solution 
     One embodiment of the present specification provides a heterocyclic compound represented by the following Chemical Formula 1. 
     
       
         
         
             
             
         
       
     
     In Chemical Formula 1, 
     L1 and L2 are each independently a direct bond; a substituted or unsubstituted C6 to C60 arylene group; or a substituted or unsubstituted divalent C2 to C60 heterocyclic group, 
     Ar1 is a substituted or unsubstituted C2 to C60 heterocyclic group including N, 
     Ar2 is —N(R106)(R107); or a substituted or unsubstituted C2 to C60 heterocyclic group, 
     R1 and R2 are each independently hydrogen; deuterium; a halogen group; a substituted or unsubstituted C1 to C60 alkyl group; a substituted or unsubstituted C3 to C60 cycloalkyl group; a substituted or unsubstituted C6 to C60 aryl group; or a substituted or unsubstituted C2 to C60 heterocyclic group, 
     R106 and R107 are each independently hydrogen; deuterium; a halogen group; an alkyl group; an alkenyl group; an alkoxy group; a cycloalkyl group; an aryl group; or a heterocyclic group, 
     r1 and r2 are each an integer of 1 to 4, and 
     when r1 and r2 are each 2 or greater, substituents in the parentheses are the same as or different from each other. 
     Another embodiment of the present application provides an organic light emitting device including a first electrode; a second electrode provided opposite to the first electrode; and an organic material layer provided between the first electrode and the second electrode, wherein the organic material layer includes one or more types of the heterocyclic compound represented by Chemical Formula 1. 
     Advantageous Effects 
     A compound described in the present specification can be used as a material of an organic material layer of an organic light emitting device. The compound is capable of performing a role of a hole injection material, a hole transfer material, a light emitting material, an electron transfer material, an electron injection material or the like in the organic light emitting device. Particularly, the compound can be used as a light emitting layer material of an organic light emitting device. For example, the compound can be used alone as a light emitting material, or can be used as a host material of a light emitting layer. 
     By Chemical Formula 1 having a structure in which naphthobenzofuran is disubstituted with an amine group or a heterocyclic group including nitrogen, the HOMO level is delocalized helping with electron and hole transfers. Accordingly, Chemical Formula 1 is readily used as a host, and effects of increasing efficiency and lifetime are obtained depending on the substituted position of the naphthobenzofuran. 
     By introducing various substituents to the naphthobenzofuran of Chemical Formula 1, a hole transfer ability of the central structure increases, and the expanded conjugation structure can stabilize homo energy. This forms proper energy level and band gap as a host material resulting in an increase in the excitons in the light emitting area, and effects of increasing driving voltage and efficiency of the device are obtained. 
     Specifically, when using the compound represented by Chemical Formula 1 in an organic material layer, a driving voltage of the device can be lowered, light efficiency can be enhanced, and lifetime properties of the device can be enhanced.

     MODE FOR DISCLOSURE 
     Hereinafter, the present specification will be described in more detail. 
     In the present specification, a certain part “including” certain constituents means capable of further including other constituents, and does not exclude other constituents unless particularly stated on the contrary. 
     The term “substitution” means a hydrogen atom bonding to a carbon atom of a compound being changed to another substituent, and the position of substitution is not limited as long as it is a position at which the hydrogen atom is substituted, that is, a position at which a substituent can substitute, and when two or more substituents substitute, the two or more substituents may be the same as or different from each other. 
     In the present specification, 
     
       
         
         
             
             
         
       
     
     means a substituted position. 
     In the present specification, “substituted or unsubstituted” means being substituted with one or more substituents selected from the group consisting of a C1 to C60 linear or branched alkyl group; a C2 to C60 linear or branched alkenyl group; a C2 to C60 linear or branched alkynyl group; a C3 to C60 monocyclic or polycyclic cycloalkyl group; a C2 to C60 monocyclic or polycyclic heterocycloalkyl group; a C6 to C60 monocyclic or polycyclic aryl group; a C2 to C60 monocyclic or polycyclic heterocyclic group; a silyl group; a phosphine oxide group; and an amine group, or being unsubstituted, or being substituted with a substituent linking two or more substituents selected from among the substituents illustrated above, or being unsubstituted. 
     In the present specification, a “case of a substituent being not indicated in a chemical formula or compound structure” means that a hydrogen atom bonds to a carbon atom. However, since deuterium ( 2 H) is an isotope of hydrogen, some hydrogen atoms may be deuterium. 
     In one embodiment of the present application, a “case of a substituent being not indicated in a chemical formula or compound structure” may mean that positions that may come as a substituent may all be hydrogen or deuterium. In other words, since deuterium is an isotope of hydrogen, some hydrogen atoms may be deuterium that is an isotope, and herein, a content of the deuterium may be from 0% to 100%. 
     In one embodiment of the present application, in a “case of a substituent being not indicated in a chemical formula or compound structure”, hydrogen and deuterium may be mixed in compounds when deuterium is not explicitly excluded such as a deuterium content being 0%, a hydrogen content being 100% or substituents being all hydrogen. 
     In one embodiment of the present application, deuterium is one of isotopes of hydrogen, is an element having deuteron formed with one proton and one neutron as a nucleus, and may be expressed as hydrogen-2, and the elemental symbol may also be written as D or  2 H. 
     In one embodiment of the present application, an isotope means an atom with the same atomic number (Z) but with a different mass number (A), and may also be interpreted as an element with the same number of protons but with a different number of neutrons. 
     In one embodiment of the present application, a meaning of a content T % of a specific substituent may be defined as T2/T1×100=T % when the total number of substituents that a basic compound may have is defined as T1, and the number of specific substituents among these is defined as T2. 
     In other words, in one example, having a deuterium content of 20% in a phenyl group represented by 
     
       
         
         
             
             
         
       
     
     means that the total number of substituents that the phenyl group may have is 5 (T1 in the formula), and the number of deuterium among these is 1 (T2 in the formula). In other words, having a deuterium content of 20% in a phenyl group may be represented by the following structural formulae. 
     
       
         
         
             
             
         
       
     
     In addition, in one embodiment of the present application, “a phenyl group having a deuterium content of 0%” may mean a phenyl group that does not include a deuterium atom, that is, a phenyl group that has 5 hydrogen atoms. 
     In the present specification, the halogen may be fluorine, chlorine, bromine or iodine.

     1) Preparation of Intermediate G 
     After dissolving Intermediate F (10 g, 30.15 mmol), bis(pinacolato)diboron (11.5 g, 45.23 mmol), PdCl 2 dppf ([1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride) (1.1 g, 1.5 mmol) and KOAc (potassium acetate) (7.4 g, 75.37 mmol) in 1,4-dioxane (100 mL), the result was stirred for 3 hours at 100° C. The mixture solution completed with the reaction was concentrated, dissolved in MC, and extracted with water. The organic layer was dried with anhydrous MgSO 4 , and then silica gel filtered. The solvent was removed from the filtered filtrate using a rotary evaporator to obtain Intermediate G, brown solid, in a crude state without separate purification. 
     2) Preparation of Intermediate I 
     After dissolving Intermediate G (9.7 g, 25.62 mmol), Intermediate H (2-chloro-4,6-diphenyl-1,3,5-triazine) (6.85 g, 25.62 mmol), Pd(PPh 3 ) 4  (tetrakis(triphenylphosphine)palladium (0)) (1.48 g, 1.28 mmol) and K 2 CO 3  (7.08 g, 51.24 mmol) in dioxane (80 mL) and H 2 O (20 mL), the result was stirred for 6 hours at 100° C. After the reaction was completed, precipitated solid was filtered, and washed with H 2 O, methanol and acetone to obtain Intermediate I (6.7 g), white solid, in a 54% yield. 
     3) Preparation of Compound 1 
     After dissolving Intermediate I (6.7 g, 13.83 mmol), Intermediate J (diphenylamine) (2.34 g, 13.83 mmol), Pd 2 (dba) 3  (tris(dibenzylideneacetone)dipalladium(0)) (0.63 g, 0.7 mmol), XPhos (1.33 g, 2.8 mmol) and Na t Obu (sodium tert-butoxide) (2.66 g, 27.66 mmol) in toluene (50 mL), the result was stirred for 3 hours at 100° C. After the reaction was completed, precipitated solid was filtered, and washed with H 2 O and methanol. The filtered solid was dried, and then silica gel filtered after being dissolved in an excess amount of hot 1,2-dichlorobenzene solvent. After removing the solvent from the filtered filtrate using a rotary evaporator, the result was precipitated using acetone, and then the precipitate was filtered to obtain Compound 1 (5.54 g), yellow solid, in a 65% yield. 
     Target compounds of the following Table 3 were synthesized in the same manner as in Preparation Example 3 except that Intermediates F, H and J of the following Table 3 were used instead of Intermediates F, H and J of Preparation Example 3.

     1) Preparation of Intermediate K 
     After dissolving Intermediate F (10 g, 30.15 mmol), Intermediate J (5H-benzo[b]carbazole) (6.5 g, 30.15 mmol), Pd 2 (dba) 3  (1.38 g, 1.5 mmol), XPhos (2-dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl) (2.86 g, 6 mmol) and Na t OBu (5.8 g, 60.3 mmol) in toluene (100 mL), the result was stirred for 3 hours at 100° C. After the reaction was completed, precipitated solid was filtered, and washed with H 2 O and methanol. The filtered solid was dried, and then silica gel filtered after being dissolved in an excess amount of hot 1,2-dichlorobenzene solvent. After removing the solvent from the filtered filtrate using a rotary evaporator, the result was precipitated using acetone, and then the precipitate was filtered to obtain Intermediate K (11.14 g), white solid, in a 79% yield. 
     2) Preparation of Intermediate L 
     After dissolving Intermediate K (11.14 g, 23.81 mmol), bis(pinacolato)diboron (9.08 g, 35.71 mmol), Pd 2 (dba) 3  (1.1 g, 1.2 mmol), sPhos (2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl) (2 g, 4.8 mmol) and KOAc (7 g, 71.43 mmol) in 1,4-dioxane (100 mL), the result was stirred for 3 hours at 100° C. The mixture solution completed with the reaction was concentrated, dissolved in MC, and extracted with water. The organic layer was dried with anhydrous MgSO 4 , and then silica gel filtered. The solvent was removed from the filtered filtrate using a rotary evaporator to obtain Intermediate L, brown solid, in a crude state without separate purification. 
     3) Preparation of Compound 85 
     After dissolving Intermediate L (10.65 g, 19.04 mmol), Intermediate H (2-chloro-4,6-diphenyl-1,3,5-triazine) (5.1 g, 19.04 mmol), Pd(PPh 3 ) 4  (1.1 g, 0.95 mmol) and K 2 CO 3  (5.3 g, 38.08 mmol) in dioxane (80 mL) and H 2 O (20 mL), the result was stirred for 6 hours at 100° C. After the reaction was completed, precipitated solid was filtered, and washed with H 2 O, methanol and acetone to obtain Compound 85 (8.1 g), white solid, in a 64% yield. 
     Target compounds of the following Table 4 were synthesized in the same manner as in Preparation Example 4 except that Intermediates F, H and J of the following Table 4 were used instead of Intermediates F, H and J of Preparation Example 4.

     1) Manufacture of Organic Light Emitting Device 
     A glass substrate on which indium tin oxide (ITO) was coated as a thin film to a thickness of 1,500 A was cleaned with distilled water ultrasonic waves. After the cleaning with distilled water was finished, the substrate was ultrasonic cleaned with solvents such as acetone, methanol and isopropyl alcohol, then dried, and ultraviolet ozone (UNVO) treatment was conducted for 5 minutes using LIV in a ultraviolet (UV) cleaner. After that, the substrate was transferred to a plasma cleaner (PT), and after conducting plasma treatment under vacuum for ITO work function and residual film removal, the substrate was transferred to a thermal deposition apparatus for organic deposition. 
     On the transparent ITO electrode (anode), a hole injection layer 2-TNATA (4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine) and a hole transfer layer NPB (N,N′-di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine), which are common layers, were formed. 
     
       
         
         
             
             
         
       
     
     A light emitting layer was thermal vacuum deposited thereon as follows. The light emitting layer was deposited to 500 Å using a compound described in the following Table 7 as a red host, and doping (piq) 2 (Ir)(acac) (bis(1-phenylisoquinoline)(acetylacetonate)iridium(III)) to the host by 3% as a red phosphorescent dopant. After that, BCP (2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline) was deposited to 60 Å as a hole blocking layer, and Alq 3  was deposited to 200 Å thereon as an electron transfer layer. Lastly, an electron injection layer was formed on the electron transfer layer by depositing lithium fluoride (LiF) to a thickness of 10 Å, and then a cathode was formed on the electron injection layer by depositing an aluminum (Al) cathode to a thickness of 1,200 Å, and as a result, an organic electroluminescent device was manufactured. 
     Meanwhile, all the organic compounds required to manufacture the OLED were vacuum sublimation purified under 10 −8  torr to 10 −6  torr for each material to be used in the OLED manufacture. 
     For each of the organic electroluminescent devices manufactured as above, electroluminescent (EL) properties were measured using M7000 manufactured by McScience Inc., and with the measurement results, T 90  was measured when standard luminance was 6,000 cd/m 2  through a lifetime measurement system (M6000) manufactured by McScience Inc. Properties of the organic electroluminescent device of the present disclosure are as shown in the following Table 7.

     As seen from Table 7, it was identified that, when using the compound corresponding to Chemical Formula 1 in the light emitting layer of the organic light emitting device, excellent effects were obtained in the properties of lifetime, efficiency and driving voltage compared to the cases without the compound. Introducing naphthobenzofuran with increased n-conjugation to the dibenzofuran linker enables suitable use as a red host, and helps with better lifetime, efficiency and enhancement in driving voltage. 
     &lt;Experimental Example 2&gt; Manufacture of Organic Light Emitting Device (Red N+N Mixed Host) 
     A glass substrate on which ITO was coated as a thin film to a thickness of 1,500 Å was cleaned with distilled water ultrasonic waves. After the cleaning with distilled water was finished, the substrate was ultrasonic cleaned with solvents such as acetone, methanol and isopropyl alcohol, then dried, and UVO treatment was conducted for 5 minutes using UV in a UV cleaner. After that, the substrate was transferred to a plasma cleaner (PT), and after conducting plasma treatment under vacuum for ITO work function and residual film removal, the substrate was transferred to a thermal deposition apparatus for organic deposition. 
     On the transparent ITO electrode (anode), a hole injection layer 2-TNATA (4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine) and a hole transfer layer NPB (N,N′-di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine), which are common layers, were formed. 
     A light emitting layer was thermal vacuum deposited thereon as follows. As the light emitting layer, two types of compounds described in the following Table 8 were premixed and deposited to 400 Å in one source of supply as a red host, and as a red phosphorescent dopant, (piq) 2 (Ir)(acac) was doped by 3% and deposited. After that, BCP was deposited to 60 Å as a hole blocking layer, and Alq 3  was deposited to 200 Å thereon as an electron transfer layer. Lastly, an electron injection layer was formed on the electron transfer layer by depositing lithium fluoride (LiF) to a thickness of 10 Å, and then a cathode was formed on the electron injection layer by depositing an aluminum (Al) cathode to a thickness of 1,200 Å, and as a result, an organic electroluminescent device was manufactured. 
     Meanwhile, all the organic compounds required to manufacture the OLED were vacuum sublimation purified under 10 −8  torr to 10 −6  torr for each material to be used in the OLED manufacture. 
     For each of the organic electroluminescent devices manufactured as above, electroluminescent (EL) properties were measured using M7000 manufactured by McScience Inc., and with the measurement results, T 90  was measured when standard luminance was 6,000 cd/m 2  through a lifetime measurement system (M6000) manufactured by McScience Inc. Properties of the organic electroluminescent device of the present disclosure are as shown in the following Table 8.

     &lt;Experimental Example 3&gt; Manufacture of Organic Light Emitting Device (Red N+P Mixed Host) 
     A glass substrate on which ITO was coated as a thin film to a thickness of 1,500 Å was cleaned with distilled water ultrasonic waves. After the cleaning with distilled water was finished, the substrate was ultrasonic cleaned with solvents such as acetone, methanol and isopropyl alcohol, then dried, and UVO treatment was conducted for 5 minutes using UV in a UV cleaner. After that, the substrate was transferred to a plasma cleaner (PT), and after conducting plasma treatment under vacuum for ITO work function and residual film removal, the substrate was transferred to a thermal deposition apparatus for organic deposition. 
     On the transparent ITO electrode (anode), a hole injection layer 2-TNATA (4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine) and a hole transfer layer NPB (N,N′-di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine), which are common layers, were formed. 
     A light emitting layer was thermal vacuum deposited thereon as follows. As the light emitting layer, two types of compounds described in the following Table 9 were premixed and deposited to 400 Å in one source of supply as a red host, and as a red phosphorescent dopant, (piq) 2 (Ir)(acac) was doped by 3% and deposited. After that, BCP was deposited to 60 Å as a hole blocking layer, and Alq 3  was deposited to 200 Å thereon as an electron transfer layer. Lastly, an electron injection layer was formed on the electron transfer layer by depositing lithium fluoride (LiF) to a thickness of 10 Å, and then a cathode was formed on the electron injection layer by depositing an aluminum (Al) cathode to a thickness of 1,200 Å, and as a result, an organic electroluminescent device was manufactured. 
     Meanwhile, all the organic compounds required to manufacture the OLED were vacuum sublimation purified under 10 −8  torr to 10 −6  torr for each material to be used in the OLED manufacture. 
     For each of the organic electroluminescent devices manufactured as above, electroluminescent (EL) properties were measured using M7000 manufactured by McScience Inc., and with the measurement results, T 90  was measured when standard luminance was 6,000 cd/m 2  through a lifetime measurement system (M6000) manufactured by McScience Inc. Properties of the organic electroluminescent device of the present disclosure are as shown in the following Table 9.

     As seen from Tables 8 and 9, effects of more superior efficiency and lifetime were obtained when including both the N+N or N+P compounds in the organic material layer of the organic light emitting device. Such results may lead to a forecast that an exciplex phenomenon occurs when including the two compounds at the same time. Particularly, the exciplex phenomenon of the N+P compounds is a phenomenon of releasing energy having sizes of a donor (p-host) HOMO level and an acceptor (n-host) LUMO level due to electron exchanges between two molecules. When a donor (p-host) having a favorable hole transfer ability and an acceptor (n-host) having a favorable electron transfer ability are used as a host of a light emitting layer, holes are injected to the p-host and electrons are injected to the n-host, and therefore, a driving voltage may decrease, which resultantly helps with enhancement in the lifetime.
