Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is a divisional application of Chinese Patent Application No. 202010080326.5, claiming the benefit of Korean Patent Application No. 10-2019-0041497 filed with the Korean Intellectual Property Office on April 9, 2019, the entire contents of which are incorporated herein by reference. Technical Field

[0003] One or more aspects of embodiments of the present disclosure relate to a condensed cyclic compound and an organic light-emitting device including the condensed cyclic compound. Background Art

[0004] Organic light-emitting devices are self-emissive devices that can produce full-color images, and also have wide viewing angles, high contrast, short response times, and superior characteristics in terms of brightness, driving voltage, and / or response speed compared to devices in the art.

[0005] In an example, an organic light-emitting device may include a first electrode arranged (e.g., placed) on a substrate, and a hole transport region, an emission layer, an electron transport region, and a second electrode sequentially arranged on the first electrode. Holes provided by the first electrode may move toward the emission layer through the hole transport region, and electrons provided by the second electrode may move toward the emission layer through the electron transport region. Carriers (e.g., holes and electrons) may then recombine in the emission layer to generate excitons. These excitons transition from an excited state to a ground state, thereby generating light. Summary of the invention

[0118] In one or more than one embodiment, the fused cyclic compound can be selected from Compound 1 to Compound 117:

[0119]

[0120]

[0121]

[0122]

[0123]

[0124]

[0125]

[0126]

[0128]

[0129]

[0130]

[0131]

[0132] Since the fused cyclic compound according to one or more embodiments includes the fused cyclic structure represented by Formula 1, the fused cyclic compound may have high oscillator strength due to multiple resonance and may have a small ΔE since the singlet energy level and triplet energy level of the molecule do not overlap with each other. st In this regard, even at room temperature, antiphase intersystem crossing from a triplet excited state to a singlet excited state by thermal activation may be possible. Therefore, the fused cyclic compound represented by Formula 1 may exhibit delayed fluorescence. Since the excitons in the triplet state are used for light emission, the luminous efficiency may be improved.

[0133] For example, in the structure represented by Formula 1, since X 1 and X 2 is represented by an atom with electron donating properties, and since X 1 and X 2 The benzene part is located in a para position relative to the boron atom (the benzene part is located between the boron atom and X 1 and X 2 The possibility of having a charge transfer characteristic in a higher-order triplet phase higher than T1 or higher can be increased, thereby having a small E st .

[0134] In addition, in the structure represented by Formula 1, 1 and X 2 The fused ring The angle of bonding with the adjacent 1,4-azahydrocarbyl boron is reduced to suppress the decrease of the T1 energy of the fused cyclic compound. Therefore, the E of the fused cyclic compound according to one or more embodiments can be reduced. st For example, in formula 1-1 (when X 1 N(R 16 ) and X 2 N(R 18 )) contains X 1 or X 2 The fused ring has an amine (*-N(Ar 1 )-*' or *-N(Ar 2 )-*') is substituted at the 4-position of each carbazole ring. In this example, as shown below, since *-N(Ar 1 )-*' or *-N(Ar 2 )-*' relative to the partial structure of the biphenyl group connected to the ortho position, so the reduction of T1 energy can be reduced. Therefore, the fused cyclic compound according to one or more embodiments can have a relatively small ΔE st .

[0135] Formula 1-1

[0136]

[0137] In addition, since the fused cyclic compound represented by Formula 1 has a bulky structure, the distance between dopant molecules can be increased, thereby reducing dexter energy transfer. Therefore, the service life deterioration caused by the increase of triplet concentration, for example, the service life deterioration caused by triplet-triplet annihilation (TTA) and / or triplet-polaron quenching (TPQ) can be reduced.

[0138] For example, the fused cyclic compound represented by Formula 1 may satisfy Equation 1:

[0139] Equation 1

[0140] △E st =S1–T1≤0.4eV.

[0141] In Equation 1, S1 is the singlet energy level of the fused cyclic compound, and

[0142] T1 is the triplet energy level of the fused cyclic compound.

[0143] In addition, the fused cyclic compound may include a group represented by Formula 2 in the molecular structure. In the group represented by Formula 2, a carbon atom at a specific position of the benzene part (“C 4 ”) can be linked to the nitrogen atom of the amine group. For example, when X 3 When the fused ring is carbazole, the 4-position of carbazole can be connected to a nitrogen atom or an amine group. Due to such structural characteristics, the carbon atom at another position (e.g., "C 1 ”, “C 2 ” and / or “C 3 Compared with the amine-containing compound in which the condensed cyclic compound is connected to the carbon (carbon) and nitrogen atoms, the condensed cyclic compound may have a relatively high triplet energy. From the same point of view, it can be understood that as the connection structure changes in the order of para, meta and ortho positions, a trend of increasing triplet energy is observed in the biphenyl structure. According to one or more embodiments, since the condensed cyclic compound may have a relatively small ΔE st , thus the thermally activated delayed fluorescence properties can be improved.

[0144] The fused cyclic group including the group represented by Formula 2 has a relatively high probability of being positioned in a perpendicular bending direction relative to the plane including the core structure. This can lead to steric hindrance to the molecule, thereby preventing or reducing the approach to adjacent molecules and reducing dexter energy transfer. Therefore, as described above, the deterioration of the service life caused by the increase in triplet concentration can be reduced.

[0145]

[0146] In addition, since the condensed cyclic compound represented by Formula 1 has a relatively high charge (hole or electron) transport capability, it is possible to improve the exciton formation ratio in the emission layer of the organic light-emitting device including the condensed cyclic compound represented by Formula 1. Therefore, the organic light-emitting device can have a low driving voltage, high efficiency, a long service life, and a high maximum quantum efficiency.

[0147] The synthesis method for the fused cyclic compound represented by Formula 1 should be apparent to one of ordinary skill in the art by referring to the following examples.

[0148] The fused cyclic compound represented by Formula 1 can be used between a pair of electrodes of an organic light-emitting device. For example, the fused cyclic compound represented by Formula 1 can be included in at least one selected from a hole transport region, an electron transport region, and an emission layer. In one or more embodiments, the fused cyclic compound represented by Formula 1 can be used as a material for a covering layer located outside a pair of electrodes of an organic light-emitting device.

[0149] One or more embodiments of the present disclosure provide an organic light-emitting device including: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, the organic layer including an emission layer and at least one condensed cyclic compound represented by Formula 1.

[0154] The hole transport region may include a hole injection layer, a hole transport layer, an emission assisting layer, an electron blocking layer, or any combination thereof, and

[0155] The electron transport region may include a hole blocking layer, an electron transport layer, an electron injection layer, or any combination thereof.

[0156] In one or more embodiments, the emission layer of the organic light-emitting device may include at least one fused cyclic compound. The fused cyclic compound included in the emission layer may serve as a thermally activated delayed fluorescence (TADF) emitter, so that the emission layer may emit delayed fluorescence.

[0157] In one or more embodiments, the emission layer of the organic light-emitting device may include at least one fused cyclic compound and may further include a host. Here, the host may include at least one selected from anthracene-based compound, pyrene-based compound, spiro-bifluorene-based compound, carbazole-based compound, benzimidazole-based compound, and phosphine oxide-based compound. The amount of the host included in the emission layer may be greater than the amount of the fused cyclic compound included in the emission layer. For example, based on 100 parts by weight of the emission layer, the amount of the host may be from about 0.1 parts by weight to about 30 parts by weight.

[0158] In one or more embodiments, the emission layer of the organic light-emitting device may include the condensed cyclic compound, and may emit blue light having a maximum emission wavelength of 420 nm to 480 nm both inclusive.

[0159] In one or more embodiments, the hole transport region of the organic light-emitting device may include a hole transport layer, and the hole transport layer may include a first hole transport layer and a second hole transport layer.

[0160] The term "organic layer" as used herein may refer to a single layer and / or a plurality of layers disposed (positioned) between a first electrode and a second electrode of an organic light-emitting device. Materials included in the "organic layer" are not limited to organic materials.
