Technical Field
The present disclosure relates to a novel compound and an organic light emitting device including the same.
Background
Organic Light Emitting Devices (OLEDs) have excellent viewing angles and contrast ratios compared to Liquid Crystal Displays (LCDs), and are lightweight and ultra-thin since a backlight is not required as in LCDs. In such an organic light emitting device structure, when a driving voltage is applied between a cathode and an anode, electrons and holes are injected into a light emitting layer from the cathode and the anode, respectively. Thus, excitons are generated in the light emitting layer and fall to a ground state to emit light.

wherein a + m is more than or equal to 0 and less than or equal to 4, b + n is more than or equal to 0 and less than or equal to 4, c + o is more than or equal to 0 and less than or equal to 4, and d + p is more than or equal to 0 and less than or equal to 4;
x represents O or S;
each of a to D is represented by chemical formula 2:
[ chemical formula 2]
Wherein, in
Ar1or Ar2Each independently represents one selected from the group consisting of substituted or unsubstituted C6 to C60 aryl groups or monovalent groups of heteroaromatic rings having 6 to 60 aromatic ring atoms, wherein Ar1And Ar2Bonded to each other to form a ring.
In one embodiment, the compound represented by
The novel compound has excellent hole transport characteristics, and thus reduces the driving voltage of the device, thereby improving the efficiency and power consumption of the device.
In one embodiment, the novel compounds are chemically and thermally stable and have high hole mobility. Therefore, when the novel compound is applied to a hole transport layer, an auxiliary hole transport layer, and an electron blocking layer of an organic light emitting device, an organic light emitting device having high efficiency, low power consumption, and long life can be realized.
In addition, the novel compounds have a high LUMO energy level capable of blocking electrons. Therefore, the novel compound can provide a light emitting device with high efficiency when the compound is applied to an electron blocking layer of an organic light emitting device.
In one embodiment, the novel compounds have a high glass transition temperature. Accordingly, the novel compound may provide an organic light emitting device with increased stability, thereby realizing an organic light emitting device having a long lifetime.
In one embodiment, when the novel compound is applied to a blue light emitting device, the novel compound may allow the device to have a low driving voltage and high efficiency.
The organic light emitting device emits light by an organic light emitting phenomenon in which electric energy is converted into light energy in an organic light emitting layer. Materials constituting the organic light emitting device may be classified into charge injection materials for the hole injection layer and the electron injection layer, charge transport materials for the hole transport layer, the auxiliary hole transport layer, the electron blocking layer, and the electron transport layer, and light emitting materials including a host material and a dopant for the light emitting layer.
Among the charge transport materials, examples of the materials for the hole transport layer, the auxiliary hole transport layer, and the electron blocking layer may include amine derivatives having carbazole and spirofluorene skeletons. However, amine derivatives containing a carbazole skeleton have low hole mobility, which limits driving voltage, efficiency, and lifetime of a light-emitting device. The amine derivative having a spirofluorene skeleton has low solubility in an organic solvent, and thus is difficult to handle in solution. In addition, a fluorescent light-emitting material having a spirofluorene skeleton may be used as a light-emitting material used in a light-emitting layer of an organic light-emitting device. However, a fluorescent light emitting material having a spirofluorene skeleton has reduced chemical and thermal stability, low efficiency, and a short lifetime, and thus, it may be difficult to manufacture an organic light emitting device having high efficiency and a long lifetime.

SM (starting material) (7.0g, 20mmol) and phosphoric acid (1.0g, 10mmol) were dissolved in 200ml of toluene in a 500ml round bottom flask under nitrogen to form a mixture. Then, the mixture was heated and stirred while refluxing for 12 hours. The organic layer was extracted with chloroform and washed with water. The water was removed from the organic layer with anhydrous magnesium sulfate, and the organic layer was filtered. Then, the organic solvent was distilled off and removed from the organic layer under reduced pressure, followed by column purification to obtain compound 120-1(5.5g, yield: 80%).
Preparation of Compound 120-2
[ reaction formula 48]
2-Bromobiphenyl (9.3g, 40mmol) was dissolved in tetrahydrofuran (100ml) under a nitrogen atmosphere and then cooled to-78 ℃. Then, n-BuLi (2.5M, 16ml, 40mmol) was slowly added dropwise thereto, followed by stirring for 1 hour. To this was slowly added dropwise the above compound 120-1(13.2g, 40mmol), stirred for 3 hours, and then warmed to room temperature. To this was added water (100 ml). Extraction was performed with tetrahydrofuran. The obtained organic layer was concentrated and recrystallized from methanol to obtain compound 120-2(15.0g, yield: 77%).
Preparation of Compound 120-3
[ reaction formula 49]
Compound 120-2(9.7g, 20mmol) was dissolved in 100ml acetic acid under nitrogen. Then, 20ml of anhydrous sulfuric acid was added thereto. Then, the mixture was heated and stirred while refluxing for 3 hours. After completion of the reaction, the reaction mixture was cooled to room temperature, extracted with chloroform, and washed with water. Then, water was removed from the washed extract product using anhydrous magnesium sulfate, followed by filtration. Then, the organic solvent was distilled under reduced pressure and removed from the extract product to obtain compound 120-3(8.6g, yield: 92%).
Preparation of Compound 120
[ reaction formula 50]
In a 500mL round-bottom flask, under nitrogen, compound 120-3(9.3g, 20mmol), SM (starting material) (8.0g, 20mmol), Pd (OAc)2(0.45g,2mmol)、P(t-Bu)3(0.81g, 4mmol) and NaOtBu (7.7g, 80mmol) were dissolved in 200ml of toluene to form a mixture. Then, the mixture was heated and stirred whileReflux for 24 hours. The organic layer was extracted with chloroform and washed with water. The water was removed from the organic layer with anhydrous magnesium sulfate, and the organic layer was filtered. Then, the organic solvent was distilled off and removed from the organic layer under reduced pressure, followed by column purification to obtain compound 120(12.2g, yield: 86%).
