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, composed of different materials, to enhance the efficiency and stability of the device. For example, these layers may include 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 into light-emitting materials and charge-transporting materials, such as hole injection materials, hole transport materials, electron transport materials, and electron injection materials, depending on their functions. In addition, the light-emitting materials can be classified into high-molecular and low-molecular types depending on their molecular weight, and can be classified into fluorescent materials derived from the singlet excited state of electrons and phosphorescent materials derived from the triplet excited state of electrons depending on their luminescence mechanism. In addition, light-emitting materials can be classified into blue, green, and red light-emitting materials depending on their luminescence color, and yellow and orange light-emitting materials required to realize better natural colors.

[0004] Meanwhile, when only one substance is used as a light-emitting material, the maximum light-emitting wavelength shifts to a longer wavelength due to intermolecular interactions, resulting in a decrease in color purity or a decrease in device efficiency due to light-emitting attenuation. Therefore, a host / dopant system can be used as a light-emitting material to increase color purity and light-emitting efficiency through energy transfer. The principle is that when a small amount of a dopant having a smaller energy band gap than the host forming the light-emitting layer is mixed into the light-emitting layer, excitons generated in the light-emitting layer are transported to the dopant, resulting in high-efficiency light emission. At this time, the wavelength of the host shifts to the wavelength of the dopant, so light of a desired wavelength can be obtained depending on the type of dopant used.

[0005] The current portable display market is trending toward larger displays, which are increasing in size and demanding greater power consumption than traditional portable displays. Therefore, power consumption has become a crucial factor for portable displays, which rely on batteries as their limited power source. Efficiency and longevity also need to be addressed.

[0006] Efficiency, lifespan, and operating voltage are all interrelated. As efficiency increases, the operating voltage relatively decreases. As the operating voltage decreases, the crystallization of organic materials due to Joule heating generated during operation decreases, which tends to result in a longer lifespan. However, efficiency cannot be maximized simply by improving the organic layer. This is because long lifespan and high efficiency can be achieved simultaneously when the energy level and T1 value between each organic layer, and the intrinsic properties of the material (mobility, interfacial properties, etc.) are optimally combined.

[0007] Therefore, it is necessary to delay the penetration and diffusion of metal oxide from the anode electrode (ITO), which is one of the causes of shortened lifespan of organic electronic devices, into the organic layer, and to have stable characteristics against Joule heating generated when the device is operated. In addition, OLED devices are mainly formed by a deposition method, so there is a need to develop materials that can withstand the deposition process for a long time, i.e., materials with strong heat resistance.

[0008] In other words, in order to fully demonstrate the excellent characteristics of organic electronic devices, the materials that make up the organic layers within the devices, such as hole injection materials, hole transport materials, light-emitting materials, electron transport materials, and electron injection 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 among them, the development of host materials for the light-emitting layer is particularly urgent.

[0009] 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.

[0010] Accordingly, the present invention aims to provide a novel compound, an organic electric element using the same, and an electronic device thereof.

[0396] Referring to FIG. 1, an organic electric device (100) according to the present invention comprises a first electrode (110), a second electrode (170), and an organic layer comprising a single compound represented by Chemical Formula 1 or two or more compounds 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.

[0397] The organic layer may sequentially include a hole injection layer (120), a hole transport layer (130), a light-emitting layer (140), an electron transport layer (150), and an electron injection layer (160) on the first electrode (110).

A hole-blocking layer, an electron-blocking layer, a light-emitting auxiliary layer (220), a buffer layer (210), etc. may be further included, and the electron transport layer (150), etc. may also function as a hole-blocking layer. (See FIG. 2)

[0398] In addition, the organic electric device according to one embodiment of the present invention may further include a protective layer or a light efficiency improvement layer (180). This light efficiency improvement layer may be formed on a surface of both sides of the first electrode that is not in contact with the organic layer or on a surface of both sides of the second electrode that is not in contact with the organic layer. The compound or material for an organic electric device according to one embodiment of the present invention applied to the organic layer may be used as a host or dopant of a hole injection layer (120), a hole transport layer (130), a light emitting auxiliary layer (220), an electron transport auxiliary layer, an electron transport layer (150), an electron injection layer (160), a light emitting layer (140), or a material for a light efficiency improvement layer.

[0400] Meanwhile, even if the core is the same, the band gap, electrical properties, and interface properties can vary depending on which substituent is bonded at which position, so the selection of the core and the combination of sub-substituents bonded to it are also very important, and in particular, when the energy level and T1 value between each organic layer, and the inherent properties of the material (mobility, interface properties, etc.) are optimally combined, both a long lifespan and high efficiency can be achieved.

[0401] An organic light emitting device according to one embodiment of the present invention can be manufactured using a PVD (physical vapor deposition) method. For example, a metal or a conductive metal oxide or an alloy thereof is deposited on a substrate to form an anode, and an organic layer including a hole injection layer (120), a hole transport layer (130), a light emitting layer (140), an electron transport layer (150), and an electron injection layer (160) is formed thereon, and then a material that can be used as a cathode is deposited thereon.

[0402] In addition, in the present invention, the organic layer is formed by any one of a spin coating process, a nozzle printing process, an inkjet printing process, a slot coating process, a dip coating process, and a roll-to-roll process, and an organic electric device is provided, characterized in that the organic layer includes the compound or the composition for an organic electric device as an electron transport material.

[0614] Meanwhile, although the above has been described with respect to exemplary synthetic examples of the present invention or references represented by Chemical Formula 1 and Chemical Formula A, these are all based on Buchwald-Hartwig cross coupling reaction, Miyaura boration reaction, Suzuki cross-coupling reaction, Intramolecular acid-induced cyclization reaction (J. mater. Chem. 1999, 9, 2095), Pd(II)-catalyzed oxidative cyclization reaction (Org. Lett. 2011, 13, 5504), and PPh3-mediated reductive cyclization reaction (J. Org. Chem. 2005, 70, 5014), and it will be easily understood by those skilled in the art that the above reaction proceeds even if a substituent other than the substituent specified in the specific synthetic example is combined in Chemical Formula 1 or Chemical Formula A.

[0616] Compound A and Compound B were used on an ITO layer (anode) formed on a glass substrate, and Compound B was doped at a weight ratio of 98:2 to form a hole injection layer with a thickness of 10 nm. Then, Compound A was vacuum-deposited on the hole injection layer with a thickness of 110 nm to form a hole transport layer.

[0617] Next, a compound CR was vacuum-deposited on the hole transport layer to a thickness of 15 nm to form a light-emitting auxiliary layer. Thereafter, the host material of the light-emitting layer used compound P-1, a compound of the present invention, as a first host, and compound N-210, a compound of the present invention, as a second host, a mixture of the first host and the second host at a weight ratio of 5:5, and bis-(1-phenylisoquinolyl)iridium(Ⅲ)acetylacetonate (hereinafter abbreviated as '(piq)2Ir(acac)') as a dopant material, and the dopant was doped so that the weight ratio of the host and the dopant was 95:5, thereby forming a light-emitting layer with a thickness of 30 nm.

[0618] Next, compound E was vacuum-deposited on the light-emitting layer to form a hole-blocking layer with a thickness of 10 nm, and a mixture of compound F and compound G at a weight ratio of 5:5 was used to form an electron-transporting layer with a thickness of 30 nm on the hole-blocking layer. Thereafter, compound G 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.

[0627] [Example 2] to [Example 24]

[0628] An organic light-emitting device was manufactured in the same manner as Example 1, except that the compounds of the present invention described in Table 6 below were used instead of the compounds P-1 and N-210 of the present invention as phosphorescent host materials.

[0631] An organic electroluminescent device was manufactured in the same manner as in Example 1, except that the following comparative compounds A to E were used instead of the compound P-1 of the present invention as a phosphorescent host material.

[0636]

[0637] The organic electroluminescence devices manufactured in this way were subjected to a direct current bias voltage and the electroluminescence (EL) characteristics were measured using a PR-650 from Photoresearch. The measured result was 2500 cd / m 2 The T95 lifespan was measured using a lifespan measuring device manufactured by Maxscience at a reference luminance. Table 5 below shows the results of the device fabrication and evaluation.

[0638] 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.

[0639] 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.

[0641] As can be seen in Table 6 above, when a red organic electroluminescent device is manufactured using the material for an organic electroluminescent device of the present invention as a phosphorescent host material, the compound of the present invention exhibits remarkable characteristics in device performance, and particularly, excellent characteristics in terms of efficiency, compared to the case where comparative compounds A to E were used. As can be seen above, when a plurality of compounds are mixed to form a host for the light-emitting layer, it can be confirmed that there is a significant difference in characteristics depending on the type of the first compound and the second compound. Similarly, the second compound shows differences in driving voltage, efficiency, and lifespan depending on the type.

[0642] Comparing the comparative compounds A and B with the compounds of the present invention, the comparative compounds A and B have structures in which dibenzofuran or dibenzothiophene is bonded, whereas the compound of the present invention has a structure in which naphthobenzofuran or naphthobenzothiophene is bonded, which is different. This structural difference may affect the properties of the compounds, and can be confirmed through Table 7 below. Table 7 below shows the T1 energy levels of the comparative compounds A, B, and the compound P-12 of the present invention measured using the DFT Method (B3LYP / 6-31g(D)) of the Gaussian program.

[0643] Comparative Compound A Comparative Compound BP-12T1 (eV)2.4432.5172.232

[0644] As can be seen from the results in Table 7 above, it can be confirmed that the T1 of the compound P-12 of the present invention is lower than that of the comparative compounds A and B. This means that the red dopant has the lowest T1 among the phosphorescent R / G / B and the T1 energy gap with the red dopant is the lowest. In other words, it shows a very significant difference in terms of efficiency in that it can also play a role in transferring excitons from the host P-12 to the dopant or blocking excitons moving from the dopant to the hole transport layer.

[0645]

[0646] In addition, when the comparative compounds C and D are compared with the compound of the present invention, the comparative compound D is different in that benzoxazole is bound and the comparative compound C is bound with 2,3-position naphthoxazole, whereas the compound of the present invention is bound with 1,2-position or 3,4-position naphthoxazole. That is, Table 8 below shows the HOMO energy levels of the comparative compounds C, D and P-12 measured using the DFT Method (B3LYP / 6-31g(D)) of the Gaussian program.

[0647] Comparative compound C Comparative compound DP-12 HOMO (eV) -5.071-5.082-4.963

[0648] As can be seen from the results in Table 8 above, the HOMO of compound P-12 of the present invention is lower than that of comparative compounds C and D. This suggests that hole transfer between the light-emitting auxiliary layer and the host can be smoothly achieved, and in particular, hole transfer performance to the dopant is expected to be good. Therefore, the efficiency appears to be high when the compound of the present invention is applied. Table 9 below shows the CN Bond BDE calculated values ​​for the compounds of the examples.

[0649] The weakest BDE was calculated using the Bond and Ligand Dissociation panel using the Jaguar module from Schrödinger Materials Science (ver. 5.0.122, 2023-2). We used the Becke, 3-parameter, Lee-Yang-Parr method (B3LYP), and the 6-31G(d) basis set, one of the pople basis sets, for optimization and CN Bond BDE calculations.

[0650] Here, CN Bond BDE refers to the BDE of the CN Bond between the amine and naphthoxazole structures.

[0651] SampleC-N bond BDE (eV, @ Anion) Comparative compound E1.898P-122.246

[0652] The BDE presented in Table 9 above is the result measured in the oxidation state where electrons are removed from the molecule, and it is judged that the higher the BDE, the higher the structural stability. Therefore, it can be confirmed that the structural stability of the compound of the present invention is higher than that of the comparative compounds, and as a result, it is judged that it affects the overall performance of the device. In particular, it is thought that it shows remarkably superior characteristics in the lifespan aspect. Therefore, it appears that the compound of the present invention shows superior characteristics in terms of efficiency or lifespan compared to the comparative compounds A to E.

[0653] 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, rather than limit, the present invention, and the spirit and scope of the present invention are not limited by these embodiments.
