Description

Compound for organic electric element, organic electric element using the same, and electronic device thereof

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

In general, the organic light emitting phenomenon refers to a phenomenon in which electrical energy is converted into light energy using an organic material. An organic electric device using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer therebetween. Here, the organic material layer is often composed of a multi-layer structure composed of different materials in order to increase the efficiency and stability of the organic electric 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.

Materials used as organic layers in organic electric devices may be classified into light emitting materials and charge transport materials, such as hole injection materials, hole transport materials, electron transport materials, and electron injection materials, according to their functions. In addition, the light emitting materials can be classified into high molecular weight and low molecular weight according to molecular weight, and can be classified into fluorescent materials derived from singlet excited states of electrons and phosphorescent materials derived from triplet excited states of electrons according to light emitting mechanisms. there is. In addition, light emitting materials may be classified into blue, green, and red light emitting materials and yellow and orange light emitting materials required to realize better natural colors according to the light emitting color.

On the other hand, when only one material is used as a light emitting material, the maximum emission wavelength moves to a longer wavelength due to intermolecular interactions, and the color purity decreases or the efficiency of the device decreases due to the emission attenuation effect. Therefore, color purity increases and energy transfer A host/dopant system may be used as a light emitting material in order to increase luminous efficiency. 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 to emit light with high efficiency. At this time, since the wavelength of the host moves to the wavelength range of the dopant, light of a desired wavelength can be obtained according to the type of dopant used.

Currently, the size of the portable display market tends to increase with large-area displays, and as a result, power consumption greater than that required for existing portable displays is required. Therefore, power consumption has become a very important factor for portable displays that have a limited power supply source such as a battery, and efficiency and lifespan problems must also be solved.

Efficiency, lifespan, driving voltage, etc. are related to each other, and as efficiency increases, driving voltage relatively decreases. indicates a tendency to increase life expectancy. However, efficiency cannot be maximized by simply improving the organic layer. This is because long life and high efficiency can be achieved at the same time when the optimal combination of the energy level and T ₁ value between each organic material layer and the intrinsic properties of the material (mobility, interfacial property, etc.) is achieved. .

Therefore, it is necessary to develop a light emitting material that has high thermal stability and can efficiently balance charge in the light emitting layer. That is, in order to fully exhibit the excellent characteristics of organic electric devices, materials constituting the organic layer in the device, such as hole injection materials, hole transport materials, light emitting materials, electron transport materials, electron injection materials, etc. are supported by stable and efficient materials. This should be preceded, and among them, it is necessary to develop a host material for the light emitting layer.

Specifically, the compound represented by Formula 1 may be one of the following compounds, but is not limited thereto.

The compound represented by Formula 1 has a Reorganization Energy (RE) value of 0.22 to 0.30, preferably 0.23 to 0.29.

Hereinafter, the rearrangement energy is explained.

Reorganization energy refers to the energy lost due to changes in molecular structure arrangement during the movement of charges (electrons, holes). It depends on the molecular geometry, and has a characteristic that the value decreases as the difference between the neutral state PES (Potential Energy Surface) and the charged state PES is small. The RE value can be obtained by the following formula.

NONE: Neutral geometry of Neutral molecules (= NO opt.)

NOAE: Anion geometry of neutral molecules

NOCE: Cation geometry of neutral molecules

AONE: Neutral geometry of anion molecule

AOAE: Anion geometry of anion molecule (= AO opt.)

CONE: Neutral geometry of cation molecules

COCE: Cation geometry of cation molecules (= CO opt.)

The relocation energy value and the mobility of charges are in inverse proportion, and the RE value of each material directly affects the mobility under the condition that they have the same r and T values.

The relationship between RE value and mobility is expressed as follows, and is described as a charge transfer matrix element.

λ : Reorganization energy

μ : mobility

r: dimer displacement

t: intermolecular

According to the above equation, it can be seen that the smaller the RE value, the faster the charge mobility.

In order to obtain the rearrangement energy value, a simulation tool capable of calculating the potential energy according to the molecular structure is required. For example, Gaussian09 (hereinafter referred to as G09) and Schrodinger Materials Science's Jaguar (hereinafter referred to as JG) modules may be used. Both G09 and JG are tools for analyzing molecular properties through quantum mechanical (QM) calculations, and have functions to optimize molecular structures or calculate single-point energy for a given molecular structure.

The process of performing QM calculations on molecular structures requires large computational resources, for example two cluster servers may be used for such computations. Each cluster server consists of 4 node workstations and 1 master workstation, and each node uses a CPU with 36 or more cores to perform parallel computing through Symmetric Multi-processing (SMP). You can proceed with molecular QM calculations.

Calculate the optimized molecular structure and its potential energy (NONE / COCE) in the neutral / charge state required for rearrangement energy using G09. Calculate the charge state potential energy (NOCE) of the structure optimized for the neutral state and the neutral state potential energy (CONE) of the structure optimized for the charge state by changing only the charges in the two optimized structures. Then, the rearrangement energy is calculated according to the relational expression below.

Since Schrödinger provides a function that automatically proceeds with such a calculation process, it is possible to sequentially calculate the potential energy according to each state and calculate the RE value through the JG module just by providing the molecular structure (NO) of the basic state. .

As can be seen in Table 6, when the compound of the present invention is used as a host material for the light emitting layer, it can be confirmed that the efficiency is remarkably improved compared to the case where Comparative Compound A is used.

As can be seen from the above, when a plurality of compounds are mixed to form the host of the light emitting layer, the properties are different depending on the type of the first compound and the second compound, and when the same compound is applied to the second compound, depending on the type of the first compound It can be seen that there is a significant difference in characteristics. Similarly, the second compound shows a difference in driving voltage, efficiency, and life depending on the type.

Comparing Comparative Compound A with the compound of the present invention, as shown in Table 6, the overall performance of the device of the compound of the present invention is improved, and the efficiency is particularly improved. In the case of Comparative Compound A, triazine is substituted with dibenzofuran, whereas the compound represented by Chemical Formula 1 of the present invention is different in that a substituent represented by Chemical Formula A, for example, benzonaphthofuran is substituted. Therefore, it can be seen that the condensation of substituents affects the performance of the device.

Table 7 below shows the LUMO values of Comparative Compound A and Compound P-14 of the present invention measured using the DFT Method (B3LYP/6-31g(D)) of a Gaussian program.

Comparative Compound A P-14 LUMO (eV) -1.99 -2.04

Looking at Table 7, it can be seen that the compound P-14 of the present invention has a deeper (smaller) LUMO value than that of the comparative compound A.

The smaller the LUMO value, the easier the injection of electrons from the electron transport layer to the light emitting layer, resulting in better charge balance between electrons and holes in the light emitting layer. Therefore, it seems that the luminous efficiency is improved when the compound of the present invention is used as a host of the light emitting layer.

This implies that even within the same framework, physical properties may vary depending on the type of substituent, and as a result, the performance of the device may vary.

In addition, in the case of the compound of the present invention, it seems that the x value of CIE (color index) slightly increased compared to the comparative compound, and when the compound of the present invention is used as a host, it seems to affect the color of the device. That is, when a phenanthrofuran or phenanthrothiophene structure and a naphthobenzofuran or naphthobenzothiophene structure are simultaneously substituted with substituents of triazine as in the present invention, the performance of the device is maximized by the synergistic action of these substituents. seems to be
