Description

Organic light emitting device {Organic light emitting device}

The present invention relates to an organic light emitting diode having improved driving voltage, efficiency and lifetime.

In general, an organic light emitting phenomenon refers to a phenomenon in which electrical energy is converted into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon has a wide viewing angle, excellent contrast, and a fast response time, and has excellent luminance, driving voltage, and response speed characteristics, and thus many studies are being conducted.

An organic light emitting device generally has a structure including an anode, a cathode, and an organic material layer between the anode and the cathode. In order to increase the efficiency and stability of the organic light emitting device, the organic material layer is often composed of a multi-layered structure composed of different materials, 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. In the structure of this organic light emitting device, when a voltage is applied between the two electrodes, holes are injected from the anode and electrons from the cathode are injected into the organic material layer, and when the injected holes and electrons meet, excitons are formed. When it falls back to the ground state, it glows.

In the organic light emitting device as described above, the development of an organic light emitting device with improved driving voltage, efficiency, and lifespan is continuously required.

[Example]

Example 1

A glass substrate coated with ITO (indium tin oxide) to a thickness of 1000 Å was put in distilled water in which detergent was dissolved and washed with ultrasonic waves. At this time, a Fischer Co. product was used as the detergent, and distilled water filtered through a second filter of a Millipore Co. product was used as the distilled water. After washing the ITO for 30 minutes, ultrasonic cleaning was performed twice with distilled water for 10 minutes. After washing with distilled water, ultrasonic cleaning was performed with solvents such as isopropyl alcohol, acetone, and methanol, dried, and transported to a plasma cleaner. In addition, after cleaning the substrate for 5 minutes using oxygen plasma, the substrate was transferred to a vacuum deposition machine.

The following compound HI-1 was formed to a thickness of 1150 Å as a hole injection layer on the prepared ITO transparent electrode, but the following compound A-1 was p-doped at a concentration of 1.5% by weight. The following compound HT-1 was vacuum deposited on the hole injection layer to form a hole transport layer having a thickness of 800 Å. Subsequently, an electron blocking layer was formed by vacuum depositing the following compound EB-1 to a film thickness of 150 Å on the hole transport layer. Then, on the EB-1 deposited film, Compound 1-2 and Compound 2-1 prepared previously as a host and Compound Dp-7 as a dopant were vacuum-deposited at a weight ratio of 49:49:2 to form a red light emitting layer having a thickness of 400 Å. . A hole blocking layer was formed on the light emitting layer by vacuum depositing the following compound HB-1 to a film thickness of 30 Å. Subsequently, the following compound ET-1 and the following compound LiQ were vacuum deposited at a weight ratio of 2:1 on the hole blocking layer to form an electron injection and transport layer with a thickness of 300 Å. A negative electrode was formed by sequentially depositing lithium fluoride (LiF) to a thickness of 12 Å and aluminum to a thickness of 1000 Å on the electron injection and transport layer.

In the above process, the deposition rate of the organic material was maintained at 0.4 ~ 0.7 Å/sec, the deposition rate of lithium fluoride on the anode was 0.3 Å/sec, and the deposition rate of aluminum was 2 Å/sec, and the vacuum level during deposition was 2 * 10 Maintaining ^-7 to 5 * 10 ^-6 torr, an organic light emitting device was manufactured.

The results of Tables 1 to 3 were obtained by applying current to the organic light emitting devices manufactured in Examples 1 to 155 and Comparative Examples 1 to 108.

In one embodiment of the present invention, when the compound represented by Formula 1 and the compound represented by Formula 2 were co-deposited and used as a red light emitting layer, the driving voltage decreased and the efficiency and lifespan increased compared to Comparative Example, as shown in Table 1. Confirmed. In addition, as shown in Table 2, when Comparative Example Compounds B-1 to B-12 and the compound represented by Formula 2 of the present invention are co-deposited and used as a red light emitting layer, the driving voltage is generally higher and the efficiency is higher than that of the combination of the present invention. and decreased life expectancy. As shown in Table 3, even when Comparative Examples Compounds C-1 to C-6 and the compound represented by Formula 1 of the present invention were co-deposited and used as a red light emitting layer, the driving voltage increased and the efficiency and lifespan decreased.

In view of the above results, when a combination of a compound represented by Chemical Formula 1 as a first host and a compound represented by Chemical Formula 2 as a second host is used as a host in a red light emitting layer, as in an embodiment of the present invention, energy as a dopant It was confirmed that the transfer worked well. This can be inferred because the combination of Formula 1 and Formula 2 of the present invention causes a more stable balance in the light emitting layer than the combination with the comparative compound. Therefore, it can be confirmed that the efficiency and lifespan are further increased when electrons and holes in the organic light emitting device of an embodiment of the present invention are combined to form excitons.

In conclusion, it was confirmed that the driving voltage, luminous efficiency and lifetime characteristics of the organic light emitting device can be improved when the compound represented by Formula 1 and the compound represented by Formula 2 of the present invention are combined and co-evaporated and used as a host of the light emitting layer. did
