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, 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.

The composition of the present invention may contain the compound of the present invention alone, or may contain two or more different compounds in combination, or may contain the compound in combination with two or more other compounds. In other words, the composition may contain the compound corresponding to Chemical Formula 1 alone, may contain a mixture of two or more compounds of Chemical Formula 1, or may contain a mixture of the compound of Chemical Formula 1 and a compound not corresponding to the present invention. Here, the compound not corresponding to the present invention may be a single compound, or may be two or more compounds. In this case, when the compound is contained in a combination of two or more other compounds, the other compounds may be already known compounds of each organic layer, or may be compounds to be developed in the future. In this case, the compounds contained in the organic layer may be composed solely of compounds of the same type, but may also be a mixture of two or more heterogeneous compounds represented by Chemical Formula 1.

[0300] 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.

[0435] organic light-emitting diodes
[0436] [Example 1] Red organic light-emitting device (phosphorescent host)
[0437] An organic electroluminescent device was fabricated using the compound obtained through synthesis as a light-emitting host material of the light-emitting layer according to a conventional method. First, a N1-(naphthalen-2-yl)-N4,N4-bis(4-(naphthalen-2-yl(phenyl)amino)phenyl)-N1-phenylbenzene-1,4-diamine (hereinafter, 2-TNATA) film was vacuum-deposited on an ITO layer (anode) formed on a glass substrate to form a 50 nm thick hole injection layer, and then 4,4-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (hereinafter, NPB) was vacuum-deposited on the hole injection layer to a thickness of 80 nm as a hole transport compound to form a hole transport layer. After forming the hole transport layer, the compound P-2 of the present invention represented by the chemical formula 1 and the compound N-128 of the present invention represented by the chemical formula 2 were used as hosts at a weight ratio of (5:5) on the upper portion of the hole transport layer, and (piq)2Ir(acac) was doped as a dopant material at a weight ratio of 95:5 to deposit a light-emitting layer with a thickness of 40 nm. Subsequently, (1,1'-bisphenyl)-4-oleato)bis(2-methyl-8-quinolineoleato)aluminum (hereinafter referred to as BAlq) was vacuum-deposited with a thickness of 10 nm as a hole blocking layer, and bis(10-hydroxybenzo[h]quinolinato)beryllium (hereinafter referred to as BeBq2) was deposited with a thickness of 20 nm as an electron transport layer. Afterwards, LiF, a halogenated alkali metal, was deposited as an electron injection layer with a thickness of 0.2 nm, and Al was then deposited with a thickness of 150 nm and used as a cathode, thereby manufacturing an organic light emitting device.
[0438]
[0439] [Example 2] to [Example 34]
[0440] An organic light-emitting device was manufactured in the same manner as in Example 1, except that the compounds of the present invention described in Table 5 below were used instead of the compounds P-2 and N-128 of the present invention as phosphorescent host materials.

[0448] The organic electroluminescence devices manufactured in this way were applied with a forward bias DC voltage and the electroluminescence (EL) characteristics were measured using a PR-650 from Photoresearch, and 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.
[0449] 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.
[0450] 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.

[0452] As can be seen in Table 5 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 compared to the case where comparative compounds A to E were used, and particularly, exhibits excellent characteristics in terms of efficiency.
[0453] As can be seen above, when forming a host for a light-emitting layer by mixing multiple compounds, it can be confirmed that there is a significant difference in characteristics depending on the type of the first and second compounds. Similarly, there are differences in driving voltage, efficiency, and lifespan depending on the type of the second compound.
[0454] Comparing the compounds of the present invention with comparative compounds A to C, the present invention differs in that chrysene is substituted as a substituent of carbazole, whereas comparative compounds A to C are substituted with phenanthrene or triphenylene. This can be confirmed through Table 6 below.
[0455] Table 6 below shows the energy levels of comparative compounds A to C and compound P-40 of the present invention measured using the DFT Method (B3LYP / 6-31g(D)) of the Gaussian program.
[0456] Comparative Compound A Comparative Compound B Comparative Compound CP-40T12.582.652.652.46
[0457] As can be seen from the results in Table 6 above, it can be confirmed that the T1 of compound P-40 of the present invention is lower than that of comparative compounds A to C.
[0458] This means that the red dopant has the lowest T1 among phosphorescent R / G / B, and the lowest T1 energy gap with the red dopant. In other words, it simultaneously plays a role in transferring excitons from the host P-40 to the dopant and blocking excitons moving from the dopant to the hole transport layer, resulting in a very significant difference in efficiency.
[0459] In addition, when the comparative compound D and the compound of the present invention are compared, the comparative compound D has a structure in which two carbazoles are bonded, whereas the compound of the present invention has an amino group bonded to the 2nd position of the carbazole, which results in a large difference in the physical properties or morphology of the compounds (especially the HOMO level), and this results in a difference in the overall performance of the compounds.
[0460] Finally, when comparing the comparative compound E with the compound of the present invention, there is a difference in that the comparative compound E has a composition in which carbazole is not substituted, but the compound of the present invention includes carbazole.
[0461] Table 7 below describes the calculated Reorganization Energy values of comparative compounds E and P-40.
[0462] The RE ratio values listed in Table 7 below are RE hole and RE elec After calculating RE hole / RE elec It means the calculated value.
[0463] Comparative compound EP-40RE ratio 0.5451.079
[0464] If the above Table 7 is explained in detail, it can be seen that the RE ratio value of the compound P-40 of the present invention is greater than that of the comparative compound E. This means the correlation between hole mobility and electron mobility, and RE elec A higher value means a decrease in the RE ratio.
[0465] That is, RE elec The higher the RE ratio, the lower the electron mobility, which results in an increase in the luminescent region. Therefore, the wider the luminescent region, the lower the efficiency. On the other hand, the higher the RE ratio, the higher the electron mobility, which results in a narrower luminescent region, which results in an increase in efficiency. Therefore, the compound of the present invention appears to have higher efficiency than the comparative compound E.
[0466] Therefore, it appears that the efficiency is dramatically increased due to the synergistic effect that occurs by substituting a specific substituent as in the present invention.
[0467] 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. 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.
[0468] 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.
