Description

BACKGROUND

Technical Field

The present invention relates to a compound for an organic electronic element, an organic electronic element using the same, and an electronic device thereof.

Background Art

In general, organic light emitting phenomenon refers to a phenomenon that converts electric energy into light energy by using an organic material. An organic electronic element using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. Here, in order to increase the efficiency and stability of the organic electronic element, the organic material layer is often composed of a multi-layered structure composed of different materials, and for example, may include a hole injection layer, a hole transport layer, an emitting layer, an electron transport layer, an electron injection layer and the like.

A material used as an organic material layer in an organic electronic element may be classified into a light emitting material and a charge transport material, such as a hole injection material, a hole transport material, an electron transport material, an electron injection material and the like depending on its function.

Lifespan and efficiency are the most problematic in organic electroluminescent device, and as displays become larger, these problems of efficiency and lifespan must be solved. Efficiency, lifespan, and driving voltage are related to each other, and when the efficiency is increased, the driving voltage is relatively decreased, and as the driving voltage is decreased, crystallization of the organic material due to Joule heating generated during driving decreases, and as a result, the lifespan tends to increase.

However, the efficiency cannot be maximized simply by improving the organic material layer. This is because, when the energy level and T1 value between each organic material layer, and the intrinsic properties of the material (mobility, interfacial properties, etc.) are optimally combined, a long lifespan and high efficiency can be achieved at the same time.

Also, in order to solve the problem of light emission in the hole transport layer in recent organic electroluminescent devices, an emitting-auxiliary layer must exist between the hole transport layer and the emitting layer, and it is time to develop different emitting-auxiliary layers according to each emitting layer (R, G, B).

In general, electrons are transferred from the electron transport layer to the emitting layer, and holes are transferred from the hole transport layer to the emitting layer, and excitons are generated by recombination.

However, since the material used for the hole transport layer should have a low HOMO value, most have a low T1 value. As a result, excitons generated in the emitting layer are transferred to the hole transport layer, resulting in charge unbalance in the emitting layer to emit light at the hole transport layer interface.

When light is emitted at the hole transport layer interface, the color purity and efficiency of the organic electronic element are lowered, and the lifespan is shortened. Therefore, it is urgently required to develop an emitting-auxiliary layer having a high T1 value and having a HOMO level between the HOMO energy level of the hole transport layer and the HOMO energy level of the emitting layer.

Furthermore, it is necessary to develop a hole injection layer material that delays the penetration and diffusion of metal oxides from the anode electrode (ITO) into the organic layer, which is one of the causes of shortening the lifespan of organic electronic element, and that has stable characteristics, that is, a high glass transition temperature, even against Joule heating generated during device driving. The low glass transition temperature of the hole transport layer material has a characteristic of lowering the uniformity of the thin film surface during device driving, which is reported to have a significant effect on device lifespan. Moreover, OLED devices are mainly formed by a deposition method, and it is necessary to develop a material that can withstand a long time during deposition, that is, a material with strong heat resistance.

In other words, in order to fully exhibit the excellent characteristics of an organic electronic element, it should be preceded that the material constituting the organic material layer in the device, such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, emitting auxiliary layer material, etc., is supported by a stable and efficient material. but the development of a stable and efficient organic material layer material for an organic electronic device has not yet been sufficiently made. Therefore, the development of new materials is continuously required.

Referring to FIG. 1, the organic electronic element (100) according to the present invention includes a first electrode (110), a second electrode (170), and an organic material layer including a single compound or 2 or more compounds represented by Formula 1 between the first electrode (110) and the second electrode (170). In this case, the first electrode (110) may be an anode, and the second electrode (170) may be a cathode.

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

Evaluation of Manufacture of Organic Electronic Element

[Example 1] Green Organic Light Emitting Diode (Hole Transport Layer)

An organic electroluminescent device was manufactured according to a conventional method using the compound of the present invention as a hole transport layer material.

First, on an ITO layer (anode) formed on a glass substrate, N1-(naphthalen-2-yl)-N4, N4-bis(4-(naphthalen-2-yl(phenyl)amino)phenyl)-N 1-phenylbenzene-1,4-diamine (Hereinafter, abbreviated as 2-TNATA) film as a hole injection layer was vacuum-deposited to form a thickness of 60 nm. On the hole injection layer, the compound P1-1 of the present invention was vacuum-deposited to a thickness of 60 nm to form a hole transport layer. After forming the hole transport layer, CBP[4,4′-N,N′-dicarbazole-biphenyl] was used as a host, and lr(ppy)₃ [tris(2-phenylpyridine)-iridium] was used as a dopant, doped at a weight ratio of 95:5, and vacuum deposited to a thickness of 30 nm to form an emitting layer on hole transport layer. Then (1,1′-bisphenyl)-4-oleato)bis(2-methyl-8-quinolineoleato)aluminum (hereinafter abbreviated as BAlq) as a hole blocking layer was vacuum-deposited to a thickness of 10 nm, as an electron transport layer, tris(8-quinolinol)aluminum (hereinafter, abbreviated as Alq3) was deposited to a thickness of 40 nm. Thereafter, LiF, which is an alkali metal halide, was deposited as an electron injection layer to a thickness of 0.2 nm, and then Al was deposited to a thickness of 150 nm and used as a cathode to prepare an organic electroluminescent device.

[Example 2] to [Example 51] Green Organic Light Emitting Diode (Hole Transport Layer)

An organic electroluminescent device was manufactured in the same manner as in Example 1, except that the compound P1-2 to P7-3 of the present invention described in Table 4 was used instead of the compound P1-1 of the present invention as a hole transport layer material.

[Comparative Example 1] or [Comparative Example 2]

An organic electroluminescent device was manufactured in the same manner as in Example 1, except for using Comparative Compound A or Comparative Compound B instead of Compound P1-1 of the present invention as the hole transport layer material

By applying a forward bias DC voltage to the organic electroluminescent devices prepared in Examples and Comparative Examples prepared in this way, Electroluminescence (EL) characteristics were measured with PR-650 from Photoresearch, and as a result of the measurement, the T95 lifetime was measured using a lifetime measuring device manufactured by McScience at 5000 cd/m² standard luminance. Table 4 below shows the device fabrication and evaluation results.

As can be seen from the results in Table 5, when a green organic electric device is manufactured using the material for an organic electric device of the present invention as an emitting auxiliary layer material, the efficiency and lifespan of the organic electroluminescent device can be improved compared to the comparative example in which the emitting auxiliary layer is not used or the comparative compound A or the comparative compound B is used.

In other words, the results of Comparative Example 4 or Comparative Example 5 using Comparative Compound A or Comparative Compound B were superior to Comparative Example 3 without using the emitting auxiliary layer, and Examples 52 to 102 of the compound of the present invention showed remarkably excellent results in terms of efficiency and lifespan.

First, if the comparative compound A and the compound of the present invention are compared, there is a difference between the comparative compound A and the compound of the present invention in that the bonding position of the amino group to the fluorene is different. When fluorene is bonded to an amino group, the energy level (especially HOMO and LUMO) is changed depending on the bonding position, and the physical properties of the compound are changed. Accordingly, as the physical properties of the compound are changed, the charge balance in the emitting layer is increased, and light emission is performed well inside the emitting layer rather than the interface of the emitting layer. As a result, degradation at the interface of the emitting layer is also reduced, and efficiency and lifespan are improved. Therefore, it is determined that this point acts as a major factor in improving device performance during device deposition.

Second, comparing the comparative compound B and the compound of the present invention, Comparative Compound B has a structure in which a dibenzofuran structure is bonded to an amino group, and the compound of the present invention has a structure in which xanthene and thioxanthene structures are bonded to an amino group. In other words, when comparing dibenzofuran and xanthene, the xanthene structure is judged to have improved electron donating ability and improved hole properties as sp3 carbon is added. As the xanthene structure was introduced, the hole characteristics were improved and the driving voltage, efficiency, and lifespan were improved.

As a result, when the diphenylfluorene and xanthene structures are simultaneously substituted with amino groups as in the compound of the present invention, it is judged that the device performance is remarkably excellent due to the synergy between diphenylfluorene and xanthene.

Although exemplary embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Therefore, the embodiment disclosed in the present invention is intended to illustrate the scope of the technical idea of the present invention, and the scope of the present invention is not limited by the embodiment.
