Description

Technical Field

[0001] This specification relates to organic light emitting devices.

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0157413 filed in the Korean Intellectual Property Office on November 29, 2019, the entire contents of which are incorporated herein by reference. Background Art

[0003] Generally, the organic light-emitting phenomenon refers to a phenomenon in which electrical energy is converted into light energy by using organic materials. An organic light-emitting device utilizing the organic light-emitting phenomenon generally has a structure including a positive electrode, a negative electrode, and an organic material layer therebetween. Here, in many cases, the organic material layer has a multilayer structure composed of different materials to improve the efficiency and stability of the organic light-emitting device. For example, the organic material layer may be composed of a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, and the like. In such a structure of an organic light-emitting device, if a voltage is applied between the two electrodes, holes are injected into the organic material layer from the positive electrode and electrons are injected into the organic material layer from the negative electrode. When the injected holes and electrons meet each other, excitons are formed, and light is emitted when the excitons fall to the ground state again.

[0004] There is a continuing need to develop new materials for the aforementioned organic light-emitting devices.

[0024] [Explanation of Reference Numerals]

[0025] 1: Base

[0026] 2: Positive electrode

[0027] 3: Luminous layer

[0028] 4: Negative electrode

[0029] 5: Hole injection layer

[0031] 7: Electron transport layer

[0032] 8: Electron injection layer DETAILED DESCRIPTION

[0033] Hereinafter, the present specification will be described in more detail.

[0034] The present specification provides an organic light-emitting device including a light-emitting layer, the light-emitting layer including a compound represented by Formula 1 and a compound represented by Formula 2. Specifically, the compound represented by Formula 1 and the compound represented by Formula 2 are included as a host and as a dopant, respectively.

[0035] The compound represented by Formula 2 has excellent light emitting characteristics due to a narrow full width at half maximum, but its lifespan performance is slightly insufficient.

[0036] The compound represented by Formula 1 has good hole and electron transport and injection, so that the driving voltage is stable and the photoluminescence quantum yield is high. Therefore, when the compound represented by Formula 1 is used as the host of the light-emitting layer of an organic light-emitting device, the organic light-emitting device has long service life and high efficiency characteristics.

[0037] In addition, the compound represented by Formula 1 and the compound represented by Formula 2 contain deuterium. When the compound contains deuterium, the efficiency and service life of the device are improved. Specifically, when hydrogen is replaced by deuterium, the chemical properties of the compound are hardly changed, but the physical properties of the deuterated compound are changed, so that the vibration energy level is reduced. The deuterium-substituted compound can prevent the reduction of quantum efficiency caused by the reduction of intermolecular van der Waals forces or the collision caused by intermolecular vibration. In addition, the CD bond can improve the stability of the compound.

[0038] The organic light-emitting device of the present invention may include the compound represented by Formula 1 and the compound represented by Formula 2 at the same time, thereby improving the service life problem while maintaining the excellent light-emitting characteristics of the compound of Formula 2.

[0039] The compounds of Formula 1 and Formula 2 containing deuterium can be prepared by a well-known deuteration reaction. According to an exemplary embodiment of the present specification, the compounds represented by Formula 1 and Formula 2 can be formed using a deuterated compound as a precursor, or deuterium can be introduced into the compound via a hydrogen-deuterium exchange reaction using a deuterated solvent in the presence of an acid catalyst.

[0040] In the present specification, the deuterium substitution rate of a compound means "(the number of deuterium contained in the compound) / (the maximum number of hydrogens which the compound can have)".

For example, 25% substitution with deuterium of dibenzofuran means that two of the eight hydrogens of dibenzofuran are substituted with deuterium.

[0042] In this specification, the degree of deuteration can be determined by methods such as nuclear magnetic resonance spectroscopy ( 1 The amount of the product can be determined by known methods such as H NMR) or GC / MS.

[0865] Subsequently, BH-1 as a host and BD-1 as a dopant (weight ratio 95:5) were simultaneously vacuum deposited on the second hole transport layer to form a layer with a thickness of of the luminous layer.

[0866] Subsequently, the ETL is vacuum deposited to have Subsequently, LiF is vacuum deposited to have a thickness of Aluminum is then deposited to have a thickness of to form a negative electrode, thereby manufacturing an organic light-emitting device.

[0867] The structures of the compounds used in the examples are as follows.

[0868]

[0869] Examples 2 to 59

[0870] An organic light-emitting device was manufactured in the same manner as in Example 1, except that the compounds described in the following Tables 1 to 6 were each used instead of BH-1 and BD-1 as a host and a dopant of the light-emitting layer, respectively.

[0871]

[0872]

[0873]

[0874]

[0875] Comparative Examples 1 to 29

[0876] An organic light-emitting device was manufactured in the same manner as in Example 1, except that the compounds described in the following Tables 1 to 6 were each used instead of BH-1 and BD-1 as a host and a dopant of the light-emitting layer, respectively.

[0877]

[0878]

[0879] In the organic light-emitting devices of the examples and comparative examples, at 10 mA / cm 2 The driving voltage and luminous efficiency were measured at a current density of 20 mA / cm 2 The time (LT) to reach 95% compared to the initial luminance was measured at a current density of 1.5 Å, and the results are shown in the following Tables 1 to 6. In the following Tables 1 to 6, D substitution rate means deuterium substitution rate.

[0880] [Table 1]

[0881]

[0882] The lifespans of the devices made of BH-1 in which anthracene is substituted with deuterium, and BD-1, BD-4, or BD-6 in which deuterium is substituted, are shown to be the longest in Examples 1 to 3. Although Examples 4 and 5 also have longer lifespans than Comparative Examples 1 to 3, since anthracene of the host is not substituted with deuterium, the lifespans are not long compared to the substitution rate.

[0883] [Table 2]

[0884]

[0885] All of Examples 6 to 16 showed excellent device performance and long service life. Although Example 16 also had a long service life, because the anthracene portion of BH-11 was not substituted with deuterium, the service life relative to the substitution rate was not good compared to the service life of Example 6. However, Examples 6 to 16 showed better performance than Comparative Examples 4 to 9.

[0886] [Table 3]

[0887]

[0888] All of Examples 16-1 to 21 showed long service life characteristics. In the case of Example 21, because the anthracene of the host was not substituted with deuterium, the service life was slightly shorter than the substitution rate. However, all of Examples 16-1 to 21 showed better performance than Comparative Examples 10 to 13.

[0889] [Table 4]

[0890]

[0891] All of Examples 22 to 28 exhibited longer service life characteristics than Comparative Examples 14 to 17, among which Example 28 had a reduced service life increase rate compared to the substitution rate because anthracene was not substituted with deuterium.

[0892] [Table 5]

[0893]

[0894] All of Examples 29 to 43 exhibited longer service life characteristics than Comparative Examples 18 to 23, among which Examples 40 to 43 had a reduced service life increase rate compared to the substitution rate because anthracene was not substituted with deuterium.

[0895] [Table 6]

[0896]

[0897] Examples 44 and 45 have a longer service life than that of Comparative Example 24. However, the service life increase rate in Example 44 is greater than the deuterium substitution rate. This is because when the N-para position of dimethylhydrocarbazole is substituted with deuterium, there is an effect of extending the service life longer. In the same case, when the N-para position of diphenylamine is not substituted with deuterium, Examples 46 and 47 also show a longer service life.

[0898] In the case of Examples 48 to 51, when the deuterium-substituted methyl group was substituted, the rate of increase in the service life relative to the deuterium substitution rate was greater than when the methyl group was substituted at the para position of boron.

[0899] Examples 52 to 55 also have longer service lives than Comparative Examples 26 and 27, and when the para-position of N is deuterium, the increase rate is higher than when the para-position of N is hydrogen.

[0900] Examples 56 to 59 also have longer lifetimes than Comparative Examples 28 and 29, but the rate of increase varies depending on the deuterium substitution position of the dopant.

[0901] As in the case of Examples 48 to 51, when the para position of boron is -CD3, the service life is longer than when the para position of boron is -CH3.

[0902] Although the preferred exemplary embodiments of the present specification have been described above, the present invention is not limited thereto, and various modifications may be made and performed within the scope of the claims and detailed description of the present invention, and these modifications also fall within the scope of the present invention.
