[Technical field]
[0001] This specification claims the benefit of the filing date of Korean Patent Application No. 10-2021-0009589, filed with the Korean Intellectual Property Office on January 22, 2021, the entire contents of which are incorporated herein by reference.
[0002] SUMMARY OF THE DISCLOSURE This disclosure relates to methods for making deuterated anthracene compounds, reaction compositions, deuterated anthracene compounds, and compositions. [Background technology]
[0003] Compounds containing deuterium are used for various purposes, such as as labeling compounds for investigating chemical reaction mechanisms or substance metabolism, as well as for medicines, insecticides, organic electroluminescence materials, and other purposes.
[0004] It is known that aromatic compounds are substituted with deuterium to improve the lifespan of organic light-emitting diode (OLED) materials. The principle of this effect is that the LUMO energy of the CD bond becomes lower than that of the CH bond when substituted with deuterium, improving the lifespan of OLED materials.
[0005] In the case of anthracene derivatives used as materials for organic light-emitting devices, HOMO and LUMO are distributed in anthracene. When hydrogen in anthracene is deuterized, the vibrational energy in the molecule of CD bond is reduced compared to CH bond, which reduces the interaction between molecules and improves the life span of organic light-emitting devices.
[0006] The hydrogen-deuterium exchange method is mainly used as a technique for deuterizing aromatic compounds. In the hydrogen-deuterium exchange method, the deuterium source is an organic solvent such as Aceton-d6, DMSO-d6, DMF-d7, MeOH-d4, Toluene-d5, or Benzene-d6, or heavy water (D 2O), using an acid / base catalyst, supercritical heating, using a transition metal catalyst, etc. Such hydrogen-deuterium exchange methods require that the material to be deuterated must be able to withstand reaction conditions such as high temperature and pressure, require multiple treatments to achieve a high level of deuteration, and require a large amount of a relatively expensive deuteration reagent, which can be inefficient in terms of cost and time.
[0007] In order to generalize deuterated aromatic compounds as materials for organic light-emitting devices, a production method that can reduce costs by using less deuterium source is required. Summary of the Invention [Problem to be solved by the invention]
[0008] The present disclosure is directed to methods for making deuterated anthracene compounds, reaction compositions, deuterated anthracene compounds, and compositions. [Means for solving the problem]

[Chemical formula 5] [ka] In the above Chemical Formula 5, Ar1 is deuterium, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; Ar2 is hydrogen, deuterium, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group; a is an integer from 1 to 4. Effect of the Invention
[0014] The manufacturing method of one embodiment herein has the advantage of using less deuterium source, reducing costs.
[0015] The manufacturing methods of other embodiments herein have the advantage of reducing the overall process time for producing deuterated anthracene compounds. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] The present specification will be explained in detail below.
[0017] The hydrogen-deuterium exchange method is mainly used as a technique for deuterizing aromatic compounds. This hydrogen-deuterium exchange method requires that the material to be deuterized must withstand reaction conditions such as high temperature and high pressure, and may require multiple treatments to achieve a high level of deuterium exchange rate, and requires a large amount of a relatively expensive deuterium source, making it inefficient in terms of cost and time.
[0018] This invention relates to a method for synthesizing deuterated anthracene directly from benzene-d6 or halogenated benzene-d5, rather than using a hydrogen-deuterium exchange method, and using the deuterated anthracene as an intermediate for an organic light-emitting material, thereby dramatically reducing the amount of benzene-d6 or halogenated benzene-d5 used.
[0019] In addition, in the case of anthracene derivatives used as materials for organic light-emitting devices, the HOMO and LUMO are distributed in anthracene, so the conversion rate of replacing hydrogen in anthracene with deuterium is important. However, when deuterizing an anthracene derivative in the final state in which a substituent is applied to the 9th, 10th, etc. position of anthracene, it is easy to deuterate the substituent substituted on the anthracene located relatively outside, but it is difficult to replace hydrogen in anthracene that is not substituted with a substituent with deuterium. Therefore, it is no exaggeration to say that the deuterium replacement rate of anthracene derivatives depends on how much hydrogen in anthracene located inside is replaced with deuterium.
[0020] However, since the method for producing a deuterated anthracene compound of the present invention is a bottom-up method in which deuterated anthracene is directly synthesized from benzene-d6 or halogenated benzene-d5, hydrogen atoms at the remaining positions of anthracene except for the 9th and 10th positions are substituted with deuterium atoms before a substituent is substituted at the 9th or 10th position.
[0021] Therefore, in the deuterated anthracene compound produced by the method for producing a deuterated anthracene compound of the present invention, most of the hydrogen atoms of anthracene that are not substituted with a substituent are substituted with deuterium, and an anthracene compound with a high deuterium substitution rate can be more easily produced.

[0146] In one embodiment of the present specification, even if the hydrogen of the substituents of Ar1 and Ar2 is not replaced with deuterium, the deuterated anthracene compound obtained after the synthesis reaction is completed exhibits a similar life improvement effect to an anthracene compound having a deuterium substitution rate of a certain level or more (80% or more) without performing an additional deuterium substitution reaction, since the HOMO and LUMO of the anthracene derivative are distributed in anthracene.
[0147] Since an additional deuteration substitution reaction is not required, an excess amount of deuterium source is not required for the deuteration substitution reaction, which is advantageous in terms of cost and enables the production of a deuterated anthracene compound at low cost.
[0148] In one embodiment of the present specification, in the deuterated anthracene compound of the present specification, most of the positions among the 1-10 positions of anthracene that are not "substituted or unsubstituted aryl groups, or substituted or unsubstituted heterocycles" are substituted with deuterium.

[0173] Theoretically, if all hydrogen in a deuterated compound is replaced with deuterium, i.e., the deuterium replacement rate is 100%, the life characteristics will be most ideally improved.

Even if a deuterium replacement rate approaching 100% can be obtained, the investment efficiency is not good when considering process time, cost, etc.

In this case, a metal or a conductive metal oxide or an alloy thereof may be deposited on a substrate using a physical vapor deposition (PVD) method such as sputtering or e-beam evaporation to form an anode, and an organic layer including a hole injection layer, a hole transport layer, a light emitting layer, and an electron transport layer may be formed thereon, and a material that can be used as a cathode may be deposited thereon. In addition to this method, an organic light emitting device may be fabricated by sequentially depositing a cathode material, an organic layer, and an anode material on a substrate.
[0189] In addition, the material of each layer can be formed as an organic layer by a solution coating method as well as a vacuum deposition method during the manufacture of the organic light emitting device, where the solution coating method refers to, but is not limited to, spin coating, dip coating, doctor blading, inkjet printing, screen printing, spraying, roll coating, etc.

EXAMPLES
[0196] The present invention will be described in more detail below through examples. However, the following examples are intended to illustrate the present invention, and are not intended to limit the present invention. In all of the examples, (D) b , (D) c , (D) d (D) e (D) f and (D) g Each of b to g means the number of deuterium substitutions, and since the number and position of deuterium substitutions of individual compounds among the obtained compounds may differ depending on the deuterium conversion rate of each reaction, the number of deuterium substitutions b to g and the substitution position are not specified, where b is an integer of 1 to 8, c is an integer of 1 to 6, d is an integer of 1 to 5, e is an integer of 1 to 4, f is an integer of 1 to 7, and g is an integer of 1 to 7.
[0197] [Measurement of deuterium conversion rate and anthracene deuterium conversion rate] In this specification, the deuterium conversion rate and the anthracene deuterium conversion rate were measured by nuclear magnetic resonance (NMR) analysis. The detailed NMR analysis method is as follows.
[0198] After N-NMR analysis of a compound not substituted with deuterium, a material with the same structure as the compound analyzed by N-NMR but with hydrogen substituted with deuterium and an internal standard were mixed and analyzed by H-NMR. If hydrogen is 100% substituted with deuterium, hydrogen peaks at the positions substituted with deuterium cannot be observed in H-NMR, so the deuterium substitution rate for each position can be measured based on the H-NMR analysis results of the product not substituted with deuterium and the H-NMR analysis results of the deuterium substituted material.
[0199] However, in Production Examples 1 to 12 described later, the hydrogen position of anthracene in H-NMR may overlap with the hydrogen position of the substituent depending on the substituent. In this specification, when a substituent is introduced into 9-Bromo-10-(1-naphthyl)anthracene-d8, the substitution rate of anthracene deuterium is replaced with the substitution rate of deuterium of 9-Bromo-10-(1-naphthyl)anthracene-d8.

[0221] [Evaluation example] Fabrication of OLED elements A glass substrate coated with a 150 nm-thick thin film of ITO (indium tin oxide) was placed in distilled water containing detergent and ultrasonically washed. The detergent used was a product of Fischer Co., and the distilled water used was distilled water that had been filtered twice with a filter made by Millipore Co. The ITO was washed for 30 minutes, and then ultrasonically washed twice with distilled water for 10 minutes. After the distilled water washing was completed, ultrasonic washing was performed with a solvent of isopropyl alcohol, acetone, and methanol, and the substrate was dried and then transferred to a plasma cleaner. The substrate was then cleaned for 5 minutes using nitrogen plasma, and then transferred to a vacuum evaporator. The following HAT-CN compound was thermally vacuum deposited on the ITO transparent electrode to a thickness of 5 nm to form a hole injection layer. Then, HT1 was thermally vacuum deposited to a thickness of 100 nm, and then HT2 was thermally vacuum deposited to a thickness of 10 nm to form a hole transport layer. Next, any one of the following BH1 to BH11 as a host and BD as a dopant (weight ratio 97:3) were simultaneously vacuum-deposited to form a 20 nm-thick light-emitting layer. Then, ET was vacuum-deposited to a thickness of 20 nm to form an electron transport layer. Next, LiF was vacuum-deposited to a thickness of 0.5 nm to form an electron injection layer. Next, aluminum was vapor-deposited to a thickness of 100 nm to form a cathode, and an organic light-emitting device was produced.
[0222] The structures of the compounds used in the examples are as follows: [ka] [ka] [ka]
[0223] In the organic light-emitting devices manufactured in Examples 1 to 9 and Comparative Examples 1 to 4, 2 The driving voltage and luminous efficiency were measured at a current density of 20 mA / cm. 2The time (LT) required for the luminance to reach 95% of the initial luminance was measured at the current density of 100 mA. The results are shown in Table 1 below.
[0224] [Table 1]
[0225] According to Table 1, it can be seen that Examples 1 to 9, which use compounds substituted with deuterium, have lower driving voltages, higher luminous efficiencies, or longer lifetimes than Comparative Examples 1 and 2, which use compounds not substituted with deuterium.
[0226] In particular, when Example 1 using BH1 with the same backbone structure is compared with Comparative Example 1 using BH10, it can be seen that the lifetime of Example 1 in which deuterium is substituted is significantly longer than that of Comparative Example 1. In addition, when Example 2 using BH2 with the same backbone structure is compared with Comparative Example 2 using BH11, it can be seen that the lifetime of Example 2 in which deuterium is substituted is significantly longer than that of Comparative Example 2.
[0227] BH1 used in Example 1 and BH12 used in Comparative Example 3 also have the same backbone structure. In this case, BH1 was introduced by introducing additional substituents after deuterium had already been substituted during the synthesis of anthracene using benzene-d6 deuterized in a bottom-up manner. 99% of the 8 substitution positions based on anthracene were substituted with deuterium, and 30.7% of the 26 substitution positions based on the entire BH10 compound were substituted with deuterium. Meanwhile, BH12 was prepared by synthesizing BH10 through Comparative Synthesis Example 1, and then substituting deuterium into BH10 through a deuteration process through Comparative Synthesis Example 3. As a result, 91% of the 8 substitution positions based on anthracene were substituted with deuterium, and 87% of the 26 substitution positions based on the entire BH10 compound were substituted with deuterium. As a result, it can be confirmed that Comparative Example 3 using BH12 with a high deuterium conversion rate based on all compounds has a longer life than Example 1, but Example 1 has a deuterium conversion rate of 30.7% based on all compounds, but shows a life effect of 95% ((175 / 185) x 100) of the life of Comparative Example 3 with a deuterium conversion rate of 87% based on all compounds. In addition, BH1 in Example 1 directly synthesizes anthracene using benzene-d6 that is already highly deuterated, so no separate deuteration process is performed, simplifying the process and improving the life via deuterated anthracene with high efficiency.
[0228] This effect can also be confirmed by comparing BH2 used in Example 2 with BH13 used in Comparative Example 4. Specifically, it can be confirmed that Example 2, although the deuterium conversion rate based on all compounds is 36%, exhibits a life effect that is 96% ((186 / 194) x 100) of the life effect of Comparative Example 3, in which the deuterium conversion rate based on all compounds is 85%.
