Description

[Technical Field]

[0001] The present invention relates to a compound for an organic optoelectronic device, a composition for an organic optoelectronic device, an organic optoelectronic device, and a display device. [Background technology]

[0002] An organic optoelectric diode is a device that can convert electrical energy and optical energy into each other.

[0003] Organic optoelectronic devices can be broadly divided into two types based on their operating principles: one is a photoelectric device in which excitons formed by light energy are separated into electrons and holes, and the electrons and holes are transferred to different electrodes to generate electrical energy, and the other is a light-emitting device in which voltage or current is supplied to the electrodes to generate light energy from electrical energy.

[0004] Examples of organic optoelectronic devices include organic photoelectric devices, organic light emitting devices, organic solar cells, and organic photo conductor drums.

[0005] Among these, organic light emitting diodes (OLEDs) have been attracting much attention in recent years due to the increasing demand for flat panel display devices. OLEDs are devices that convert electrical energy into light, and their performance is heavily influenced by the organic materials located between the electrodes.

[0028] The electronic properties refer to the ability to receive electrons when an electric field is applied, and refer to the properties of having conduction properties according to the LUMO level, facilitating the injection of electrons formed in the negative electrode into the light-emitting layer, and the movement of electrons formed in the light-emitting layer to the negative electrode and within the light-emitting layer.

[0029] Hereinafter, a compound for an organic optoelectronic device according to an embodiment will be described.

[0030] The compound for an organic optoelectronic device according to one embodiment is represented by the following Chemical Formula 1: [ka] [Chemical formula 1A] [Chemical formula 1B] In the above Chemical Formula 1, X 1 is O or S, R 1 ~R 13 , R 17 and R 18 each independently represents hydrogen, deuterium, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, or a substituted or unsubstituted heterocyclic group having 2 to 20 carbon atoms, R 14 ~R 16 are each independently hydrogen or deuterium, Ar 1 is a substituted or unsubstituted aryl group having 6 to 20 carbon atoms or a substituted or unsubstituted heterocyclic group having 2 to 20 carbon atoms, m1 is an integer from 1 to 3; m2 is an integer from 1 to 4. The compounds represented by Chemical Formula 1A and Chemical Formula 1B are substituted with an N-carbazole at the ortho position of the phenylene linked to the triazine, with a substituted or unsubstituted phenyl group at the meta position of the phenylene relative to the triazine, and with at least one dibenzofuran (or dibenzothiophene) substituted on the triazine.

[0031] The compounds represented by Chemical Formula 1A and Chemical Formula 1B have a triazine-ortho carbazole structure, which provides excellent energy transfer efficiency to phosphorescent dopants and can be used as advantageous materials for phosphorescent hosts. The triazine-substituted meta-biphenyl structure contained in Chemical Formula 1A or Chemical Formula 1B accelerates electron mobility and increases stability compared to monophenyl structures, thereby improving lifetime when used as a phosphorescent host. In addition, the phenyl groups at the ends of the meta-biphenyl structure are substituted at the ortho and para positions, respectively, relative to the carbazole moiety, which helps expand the resonance structure of the carbazole moiety and stabilize the intramolecular hole transport moiety. This optimizes the charge balance between the intramolecular electron transport and hole transport moieties, further improving lifetime.

[0032] In addition, the ortho-position of the triazine is substituted with carbazole, which increases the dihedral angle due to the steric hindrance between the triazine and carbazole, and the triazine moiety and the carbazole moiety are twisted with each other, increasing the dihedral angle. This also results in the electron clouds of the HOMO and LUMO levels being largely separated without overlap, resulting in a small ΔEst and enabling fast energy transfer, demonstrating high efficiency, especially when applied to phosphorescent hosts. Furthermore, the side reaction pathways in the excited state are reduced, further increasing the lifetime.

[0033] In addition, by substituting at least one dibenzofuran (or dibenzothiophene) in the triazine, the electron mobility can be increased compared to diphenyltriazine or bis-biphenyltriazine, and the stability can be increased, resulting in improved driving performance and lifetime.

[0034] Furthermore, by designing the nitrogen-containing six-membered ring with three different substituents at the center, it has steric hindrance and can be deposited at a low temperature, which significantly improves the lifespan of organic light-emitting devices using it.

[0035] In the above Chemical Formula 1A and Chemical Formula 1B, R 17 When two or more R are substituted, each R 17 may be the same or different from each other.

[0036] In the above Chemical Formula 1A and Chemical Formula 1B, R 18 When two or more R are substituted, each R 18 may be the same or different from each other.

[0037] As an example, Chemical Formula 1A is represented by any one of Chemical Formulas 1A-1 to 1A-4 below. [ka] [Chemical formula 1A-1] [Chemical formula 1A-2] [ka] [Formula 1A-3] [Formula 1A-4] In Chemical Formula 1A-1 to Chemical Formula 1A-4, R 1 ~R 18 , Ar 1 , m1 and m2 are defined as above.

[0038] As an example, Chemical Formula 1B is represented by any one of Chemical Formulas 1B-1 to 1B-4 below. [ka] [Chemical formula 1B-1] [Chemical formula 1B-2] [ka] [Formula 1B-3] [Formula 1B-4] In Chemical Formula 1B-1 to Chemical Formula 1B-4, R 1 ~R 18 , Ar 1 , m1 and m2 are defined as above.

[0039] As a specific example, the formula 1 is represented by the formula 1A-3 or 1B-3.

[0040] As an example, the Ar 1 can be a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, or a substituted or unsubstituted terphenyl group.

[0041] As an example, the above-mentioned R 1 ~R 13 , R 17 and R 18 may each independently be hydrogen, deuterium, or a substituted or unsubstituted aryl group having 6 to 12 carbon atoms.

[0042] As a specific example, the R 17 and R 18 can each independently be hydrogen, deuterium, or a substituted or unsubstituted phenyl group.

After the distilled water cleaning, the substrate was ultrasonically cleaned with solvents such as isopropyl alcohol, acetone, and methanol, and then dried. The substrate was then transferred to a plasma cleaning device and cleaned using oxygen plasma for 10 minutes. The substrate was then transferred to a vacuum deposition device. Using the prepared ITO transparent electrode as the anode, Compound A doped with 3% NDP-9 (Novaled) was vacuum-deposited on the top of the ITO substrate to form a 100 Å thick hole injection layer. Compound A was then vacuum-deposited on the top of the hole injection layer to form a 1350 Å thick hole transport layer. Compound B was then vacuum-deposited on the top of the hole transport layer to form a 350 Å thick hole transport auxiliary layer. A 350 Å thick emissive layer was then vacuum-deposited on the top of the hole transport auxiliary layer using Compound 1 (synthesized in Synthesis Example 1) as the host and doped with 9 wt% PhGD as the dopant.

Using the prepared ITO transparent electrode as the anode, Compound A doped with 3% NDP-9 (Novaled) was vacuum-deposited on the top of the ITO substrate to form a 100 Å thick hole injection layer. Compound A was then deposited on the hole injection layer to a thickness of 1350 Å to form a hole transport layer. Compound E was then deposited on the hole transport layer to a thickness of 350 Å to form a hole transport auxiliary layer. Compound 1 (synthesized in Synthesis Example 1) and compound B-136 (synthesized in Synthesis Example 3) were simultaneously used as hosts on the hole transport assisting layer, and doped with 9 wt% PhGD as a dopant by vacuum deposition to form a 380 Å thick light-emitting layer.
