Abstract
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 with different materials to enhance the efficiency and stability of the device, and may include, for example, 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 according to their function into light-emitting materials and charge transport materials, such as hole injection materials, hole transport materials, electron transport materials, and electron injection materials.
[0004] The biggest issues with organic light-emitting diodes are their lifespan and efficiency, and as displays become larger in size, these efficiency and lifespan issues must be resolved.
[0005] Efficiency, lifespan, and operating voltage are interrelated. As efficiency increases, the operating voltage decreases relatively. As the operating voltage decreases, the crystallization of organic substances due to Joule heating generated during operation decreases, which results in a tendency for the lifespan to increase.
[0006] However, simply improving the organic layers does not maximize efficiency. This is because long life and high efficiency can be achieved simultaneously when the energy levels and T1 values between each organic layer, as well as the material's inherent properties (mobility, interfacial properties, etc.) are optimally combined.
[0007] In addition, in order to solve the problem of light emission in the hole transport layer in recent organic light emitting devices, a light emitting auxiliary layer must exist between the hole transport layer and the light emitting layer, and it is time to develop different light emitting auxiliary layers for each light emitting layer (R, G, B).
[0008] Typically, electrons are transferred from the electron transport layer to the light-emitting layer, and holes are transferred from the hole transport layer to the light-emitting layer, and excitons are generated through recombination.
[0009] However, since the material used in the hole transport layer must have a low HOMO value, most of them have a low T1 value, which causes excitons generated in the light-emitting layer to move to the hole transport layer, resulting in charge imbalance within the light-emitting layer and causing light emission at the hole transport layer interface.
[0010] When light is emitted at the interface of the hole transport layer, the color purity and efficiency of the organic electronic device are reduced, and its lifespan is shortened. Therefore, there is an urgent need to develop a light-emitting auxiliary layer with a high T1 value and a HOMO energy level between the HOMO energy level of the hole transport layer and the HOMO energy level of the light-emitting layer.
[0011] Meanwhile, there is a need to develop a hole injection layer material that has stable properties, i.e., a high glass transition temperature, against Joule heating generated during device operation while delaying the penetration and diffusion of metal oxides from the anode electrode (ITO), which is one of the causes of shortened lifespan of organic electronic devices. The low glass transition temperature of the hole transport layer material has the characteristic of reducing the uniformity of the thin film surface during device operation, which is reported to have a significant impact on the device lifespan. In addition, OLED devices are mainly formed by a deposition method, and there is a need to develop materials that can withstand the deposition process for a long time, i.e., materials with strong heat resistance.
[0012] In other words, in order to fully demonstrate the excellent characteristics of organic electronic devices, the materials forming the organic layers within the devices, such as hole injection materials, hole transport materials, luminescent materials, electron transport materials, electron injection materials, and luminescent auxiliary layer materials, must first be supported by stable and efficient materials. However, the development of stable and efficient organic layer materials for organic electronic devices has not yet been sufficiently accomplished. Therefore, the development of new materials continues to be required, and the development of materials for luminescent auxiliary layers is particularly urgently needed.
[0013] In order to solve the problems of the above-described background technology, the present invention has discovered a compound having a novel structure, and has also discovered that when this compound is applied to an organic electric device, the luminous efficiency, stability, and lifespan of the device can be greatly improved.
[0014] Accordingly, the present invention aims to provide a novel compound, an organic electric element using the same, and an electronic device thereof.

[0229] Referring to FIG. 1, the organic electric element (100) according to the present invention comprises a first electrode (110), a second electrode (170), and an organic layer comprising a single compound or two or more compounds represented by the chemical formula 1 between the first electrode (110) and the second electrode (170). At this time, the first electrode (110) may be an anode or positive electrode, the second electrode (170) may be a cathode or negative electrode, and in the case of an inverted type, the first electrode may be a cathode and the second electrode may be an anode.

[0386] Manufacturing and evaluation of organic electronic devices
[0387] [Example 1] Red organic light-emitting device (luminescent auxiliary layer)
[0388] First, N is formed on the ITO layer (anode) formed on the glass substrate. 1 -(naphthalen-2-yl)-N 4 ,N 4 -bis(4-(naphthalen-2-yl(phenyl)amino)phenyl)-N 1 -Phenylbenzene-1,4-diamine (abbreviated as 2-TNATA) was vacuum-deposited to a thickness of 60 nm to form a hole injection layer, and then N,N'-bis(1-naphthalenyl)-N,N'-bis-phenyl-(1,1'-biphenyl)-4,4'-diamine (abbreviated as NPB) was vacuum-deposited to a thickness of 60 nm on the hole injection layer to form a hole transport layer.
[0389] Next, the compound P-3 of the present invention was vacuum-deposited to a thickness of 20 nm on the hole transport layer to form a light-emitting auxiliary layer. Next, on the light-emitting auxiliary layer, 4,4'-N,N'-dicarbazole-biphenyl (hereinafter abbreviated as CBP) was used as a host material, and bis-(1-phenylisoquinolyl)iridium(Ⅲ)acetylacetonate (hereinafter abbreviated as (piq)2Ir(acac)) was used as a dopant, and the dopant was doped such that the weight ratio of the host and the dopant was 95:5, thereby forming a light-emitting layer having a thickness of 30 nm.
[0390] Next, (1,1'-biphenyl-4-olato)bis(2-methyl-8-quinolinolato)aluminum (hereinafter abbreviated as BAlq) was vacuum-deposited on the light-emitting layer to form a hole-blocking layer with a thickness of 10 nm, and Tris(8-hydroxyquinolinato)aluminum (hereinafter abbreviated as Alq3) was vacuum-deposited on the hole-blocking layer to a thickness of 40 nm to form an electron-transporting layer. Thereafter, 8-quinolinolato lithium (hereinafter abbreviated as Liq) was deposited on the electron-transporting layer to form an electron-injection layer with a thickness of 0.2 nm, and then Al was deposited to form a cathode with a thickness of 150 nm.

[0401] The electroluminescence (EL) characteristics were measured using PR-650 from Photoresearch by applying a forward bias DC voltage to the organic electroluminescence devices manufactured by Examples 1 to 20 and Comparative Examples 1 to 5 of the present invention, and the measurement result was 2,500 cd / m 2 The T95 lifespan was measured using a lifespan measuring device manufactured by Maxscience at a reference luminance. Table 4 below shows the results of the device fabrication and evaluation.
[0402] This measuring device allows the performance of new materials to be evaluated against reference compounds under identical conditions, without being affected by possible daily variations in deposition rate, vacuum quality or other parameters.
[0403] Since, during the evaluation, one batch contains four identically prepared OLEDs including a comparative compound, and the performance of a total of 12 OLEDs is evaluated in three batches, the values of the experimental results obtained in this way exhibit statistical significance.

[0406] Comparative compounds A to E are similar to the compounds of the present invention in that they are tertiary amine compounds containing a fluorene skeleton substituted in the molecule, but in the case of Comparative compounds A and B, R of the chemical formula 1 of the present invention a and R b Comparative Compounds C and D are similar in that a substituent is introduced at position 4 of fluorene, but are different from the compound of the present invention in that the substituent does not include an alkyl group or an aliphatic ring group. Comparative Compound E is similar in that a substituent including an alkyl group or an aliphatic ring group is substituted on a fluorene moiety, but the substitution position is different from the compound of the present invention.
[0407] To examine the influence of the compositional differences of these compounds, data measured using the DFT method (B3LYP / 6-31g(D)) of the Gaussian program for the comparative compounds and the compound of the present invention are as shown in Table 5.

As a result, when the compound of the present invention is applied to a device, it is thought that the driving voltage of the device is significantly reduced as hole injection and hole transfer from the hole transport layer to the light-emitting auxiliary layer become easier than in other comparative compounds.
[0410] For further verification, the Reorganization Energy (unit: eV, hereinafter RE) of the compounds of the present invention and comparative compounds hole ), Hole Small Polaron Stabilization Energy (unit: eV, HSPSE) and Hole Neutral Stabilization Energy (unit: eV, HNSE) were measured using molecular simulation (Schrodinger Materials Science Suite 4.9.128) and the data are shown in Table 6.

[0412] As can be seen from the results in Table 6 above, compound P-3 of the present invention has a higher RE than comparative compounds A to E. hole , it can be seen that the HSPSE and HNSE values are significantly lower.
[0413] First RE hole When compared, RE of the compound of the present invention holeIt can be confirmed that the value is significantly lower than that of other comparative compounds. As a result, when the compound of the present invention is applied to a device, hole hopping occurs more quickly within the material than in the comparative compounds, thereby improving hole mobility and allowing faster hole transfer to the light-emitting layer, which improves charge balance and significantly improves the operation and efficiency of the device.
[0414] Next, when comparing the HSPSE and HNSE values, it can be confirmed that the HSPSE and HNSE values of the compound of the present invention are significantly lower than those of the comparative compounds. This means that the compound of the present invention can reach a stable state more quickly and with less energy than the comparative compounds after receiving holes in the hole transport layer or transferring holes to the light-emitting layer within the device, and as a result, it is thought that the lifespan of the device is significantly improved.
[0415] In other words, as can be seen from the results in Tables 4 to 6, it can be confirmed that the compound satisfying all the structural features and configurations disclosed in the present invention exhibits a remarkable effect in the organic electric device, compared to the comparative compounds A to E having a structurally similar configuration to the compound of the present invention. This shows that the compound of the present invention satisfying all the specific configurations exhibits a remarkable effect, compared to other comparative compounds not described in the present specification.
[0416] These results suggest that even if the molecular components are similar, the properties of the compound, such as hole characteristics, light efficiency characteristics, energy levels, hole injection and mobility characteristics, charge balance of holes and electrons, volume density, and intermolecular distance, can differ significantly to an extent that is difficult to predict depending on the type and position of the substituted substituent, and that the performance of the device can vary not only due to the composition of a single compound but also due to complex factors.
[0417] In the case of a light-emitting auxiliary layer, it is necessary to understand the relationship between the hole transport layer and the light-emitting layer (host). Therefore, even if a similar core is used, it would be very difficult for even a person skilled in the art to infer the characteristics exhibited by the light-emitting auxiliary layer in which the compound of the present invention is used.
[0418] In addition, the evaluation results of the above-described device fabrication described the device characteristics in which the compound of the present invention was applied only to the light-emitting auxiliary layer, but the compound of the present invention can be applied to the hole transport layer or applied to both the hole transport layer and the light-emitting auxiliary layer.
[0419] The above description is merely illustrative of the present invention, and those skilled in the art will appreciate that various modifications may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in this specification are intended to illustrate, not limit, the present invention, and the spirit and scope of the present invention are not limited by these embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all techniques within a scope equivalent thereto should be interpreted as being included within the scope of the present invention.
[0420] According to the present invention, an organic device having excellent device characteristics such as high brightness, high luminescence, and long lifespan can be manufactured, and thus has industrial applicability.
