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 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]

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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 in particular, the development of materials for luminescent auxiliary layers is urgently required.

[0014] 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.

[0015] Accordingly, the present invention aims to provide a novel compound, an organic electric element using the same, and an electronic device thereof.

[0187]

[0188] 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.

[0189] 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). At this time, the remaining layers except for the light-emitting layer (140) may not be formed. 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)

[0190] 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.

[0192] 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.

[0193] 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.

[0194] 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 as an electron transport material.

[0295]

[0296] The electroluminescence (EL) characteristics were measured using PR-650 of Photoresearch by applying a forward bias DC voltage to the organic electroluminescence devices manufactured by Examples 1 to 15 of the present invention and Comparative Examples 1 and 2, and the measurement result was 2,500 cd / m2 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.

[0297] 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.

[0298] 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.

[0300] As can be seen from the results in Table 4 above, when a red organic electroluminescence device is manufactured using a material for an organic electroluminescence device, it can be confirmed that the driving voltage, lifespan, and luminous efficiency of the organic electroluminescence device are significantly improved in the examples using the compound of the present invention compared to the comparative examples using the comparative compound A or the comparative compound B as a light-emitting auxiliary layer. Comparative compound A or comparative compound B is similar to the compound of the present invention in that it is a tertiary amine compound in which 1-dibenzofuran with a substituent in the molecule is substituted is substituted, but it is different in that one of the remaining amines does not include a fluorene skeleton connected to the 9-position like the compound of the present invention.

[0301] In order 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 below.

[0302] Comparative compound A Comparative compound B HOMO (eV) -4.92-5.05-4.98

[0303] As can be seen from the results in Table 5 above, it can be confirmed that the HOMO Energy Level (hereinafter, HOMO) value of the compound of the present invention is shallower than that of Comparative Compound A and Comparative Compound B. As a result, when the compound of the present invention is applied to a device, hole injection and hole transfer from the hole transport layer to the light-emitting auxiliary layer are facilitated compared to the comparative compounds, thereby reducing hole accumulation in the hole transport region, and as a result, the driving voltage of the device is reduced and the charge balance of the light-emitting layer is improved, thereby improving efficiency and lifespan. That is, as can be seen from the results in Tables 4 and 5 above, it can be confirmed that a compound satisfying both the structural features and configurations disclosed in the present invention exhibits a remarkable effect in an organic electroluminescent device, compared to Comparative Compound A or Comparative Compound B having a structurally similar configuration to the compound of the present invention. This shows that the compound of the present invention satisfying all specific configurations exhibits a remarkable effect compared to other comparative compounds not described in the present specification.

[0304] 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.

[0305] In the case of a light-emitting auxiliary layer, the relationship between the hole transport layer and the light-emitting layer (host) must be understood. 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 in the light-emitting auxiliary layer using the compound of the present invention.

[0306] 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 may be applied to the hole transport layer or may be applied to both the hole transport layer and the light-emitting auxiliary layer.

[0307] The above description is merely an illustrative example 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 according to the following claims, and all techniques within a scope equivalent thereto should be interpreted as being included within the scope of the rights of the present invention.

[0308]

[0309]

[0310] 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.
