Description

[Technical Field]

[0001] The present invention relates to light-emitting organic molecules and their use in organic light-emitting diodes (OLEDs) and other optoelectronic devices. Summary of the Invention [Problem to be solved by the invention]

[0002] It is an object of the present invention to provide molecules suitable for use in optoelectronic devices. [Means for solving the problem]

[0003] Such objectives are achieved by the present invention, which provides a new class of organic molecules. The organic molecules according to the invention are purely organic molecules and do not contain any metal ions, in contrast to the metal complexes known to be used in optoelectronic devices. [Effects of the Invention]

[0004] According to the present invention, the organic molecules exhibit an emission maximum in the blue, sky blue, or green spectral range. The organic molecules exhibit an emission maximum, particularly between 420 nm and 520 nm, preferably between 440 nm and 495 nm, and more preferably between 450 nm and 470 nm, or particularly below 560 nm, more preferably below 550 nm, and even more preferably below 545 nm or below 540 nm. The emission maximum of the organic molecules generally exhibits an emission maximum greater than 500 nm, more preferably greater than 510 nm, and even more preferably greater than 515 nm or 520 nm. The photoluminescence quantum yield of the organic molecules according to the present invention is particularly greater than 50%. The use of the molecules according to the present invention in optoelectronic devices, such as organic light-emitting diodes (OLEDs), can achieve higher efficiency, as expressed by the emission full width at half maximum (FWHM), or higher color purity in the optoelectronic devices. Such OLEDs have higher stability than previously known emitters and OLEDs with similar hues. DETAILED DESCRIPTION OF THE INVENTION

[0469] In one embodiment, the organic molecule according to the present invention has an excited-state lifetime of 5.0 μs or less, 2.5 μs or less, specifically 2.0 μs or less, preferably 1.0 μs or less, or 0.7 μs or less, in a poly(methyl methacrylate) (PMMA) film containing 1 wt % to 5 wt %, specifically 2 wt %, of the organic molecule at room temperature.

[0470] In yet another embodiment of the present invention, the organic molecule according to the present invention has an emission peak in the visible or near-ultraviolet range, i.e., in the wavelength range of 380 nm to 800 nm, at room temperature in a poly(methyl methacrylate) (PMMA) film containing 1 wt % to 5 wt %, specifically 2 wt %, of the organic molecule, and has a full width at half maximum of less than 0.25 eV, preferably less than 0.22 eV, more preferably less than 0.18 eV, and even more preferably less than 0.15 eV or less than 0.12 eV.

[0471] Orbital energies and excited state energies are also determined through experimental methods. Energy E of molecular orbitals HOMO is determined from cyclic voltammetry measurements by methods known to those skilled in the art, which have an accuracy of 0.1 eV. The energy of the lowest unoccupied molecular orbital, E LUMO is EHOMO +E gap where E gap is determined as follows: for the host compound, unless otherwise specified, the onset of the emission spectrum of a poly(methyl methacrylate) (PMMA) film containing 10 wt % of the host is E gap For the emitter molecule, E gap is 1 It is determined as the energy at which the excitation spectrum and emission spectrum of a PMMA film having 2 wt% to 5 wt% of the emitter intersect. gap is determined as the energy at which the excitation spectrum and emission spectrum of a PMMA film containing 1 wt % to 5 wt %, specifically 2 wt %, of the emitter intersect.

[0472] The energy of the first excited triplet state T1 is determined from the onset of the emission spectrum at low temperatures, typically 77 K. For host compounds where the first excited singlet state and the lowest triplet state are energetically separated by >0.4 eV, phosphorescence can generally be seen as a normal-state spectrum in 2-Me-THF. Thus, triplet energies are also determined from the onset of the phosphorescence spectrum. For TADF emitter molecules, the energy of the first excited triplet state T1 is determined from the onset of the delayed emission spectrum at 77 K, and unless otherwise specified, is measured on a PMMA film containing 1 wt% to 5 wt%, specifically 2 wt%, of the emitter. For organic molecules according to the present invention, the energy is measured on a PMMA film containing 1 wt% to 5 wt%, specifically 2 wt%, of the organic molecule according to the present invention. For both the host compound and the emitter compound, the energy of the first excited singlet state S1 is determined from the onset of the emission spectrum measured in a PMMA film containing 10 wt % of the host compound or emitter compound, unless otherwise specified, and in the case of the organic molecule according to the present invention, it is determined from the onset of the emission spectrum measured in a PMMA film containing 1 wt % to 5 wt %, specifically 2 wt %, of the organic molecule according to the present invention.

[0473] The onset of the emission spectrum is determined by calculating the intersection of a tangent to the emission spectrum with the x-axis, the tangent to the emission spectrum being set at the high energy side of the emission band and the half maximum point of the maximum intensity of the emission spectrum.

[0493] In yet another aspect, the present invention relates to an optoelectronic device comprising an organic molecule or composition of the type described herein, and more particularly to a device having a form selected from the group consisting of an organic light-emitting diode (OLED), a light-emitting electrochemical cell, an OLED sensor (e.g., an open-circuit gas sensor or vapor sensor), an organic diode, an organic solar cell, an organic transistor, an organic field-effect transistor, an organic laser, and a downward conversion device.

[0494] In a preferred embodiment, the optoelectronic device is a device selected from the group consisting of an organic light emitting diode (OLED), a light emitting electrochemical cell (LEC), and a light emitting transistor.

[0495] In one embodiment of the inventive optoelectronic device, the inventive organic molecule E is used as emissive material in the emissive layer EML.

[0496] In one embodiment of the optoelectronic device of the present invention, the light-emitting layer EML consists of the composition according to the present invention described herein.

[0497] When the optoelectronic device is an OLED, it can have, for example, the following layer structure: 1. Substrate 2. Anode layer A 3. Hole injection layer (HIL) 4. Hole transport layer (HTL) 5. Electron Blocking Layer (EBL) 6. Emitting layer (EML) 7. Hole-Blocking Layer (HBL) 8.Electron transport layer (ETL) 9.Electron injection layer (EIL) 10. Cathode layer

[0498] Here, the OLED selectively includes each layer selected from the group of HIL, HTL, EBL, HBL, ETL, and EIL, and different layers are combined, and the OLED may include one or more layers of each layer type defined above.

[0499] In one embodiment, the optoelectronic device may also be, for example, resistant to moisture, vapor, and / or gas. It may also include one or more protective layers that protect the device from harmful exposure to harmful species in environments containing them.

[0500] In one embodiment of the present invention, the optoelectronic device is an OLED having the following inverted layer structure: 1. Substrate 2. Cathode layer 3.Electron injection layer (EIL) 4.Electron transport layer (ETL) 5. Hole-Blocking Layer (HBL) 6. Emitting layer B 7. Electron Blocking Layer (EBL) 8. Hole transport layer (HTL) 9. Hole injection layer (HIL) 10. Anode layer A

[0501] Here, the OLED may include only selectively each layer selected from the group of HIL, HTL, EBL, HBL, ETL, and EIL, and different layers may be combined, and the OLED may also include one or more layers of each layer type defined above.

[0502] In one embodiment of the present invention, the optoelectronic device is an OLED that can have a stacked structure. In this structure, each unit is stacked on top of the other, unlike the typical arrangement in which the OLEDs are arranged side by side. Mixed light is generated by the OLED that exhibits the stacked structure. Specifically, white light can be generated by stacking blue, green, and red OLEDs. The OLED that exhibits the stacked structure also includes a charge generation layer (CGL), which is generally located between two OLED subunits and generally consists of an n-doped layer and a p-doped layer, with the n-doped layer of one CGL layer being closer to the anode layer.

[0503] In one embodiment of the present invention, the optoelectronic device is an OLED comprising two or more light-emitting layers between an anode and a cathode. Specifically, the so-called tandem OLED comprises three light-emitting layers, where one light-emitting layer emits red light, one light-emitting layer emits green light, and one light-emitting layer emits blue light, and optionally further comprises a charge generation layer, a blocking layer, or a transport layer between each light-emitting layer. In another embodiment, the light-emitting layers are stacked adjacent to each other. In another embodiment, the tandem OLED comprises a charge generation layer between each two light-emitting layers. Also, adjacent light-emitting layers or light-emitting layers separated by a charge generation layer may be fused together.

[0504] The substrate can be made of any material or material composition. In most cases, a glass slide is used as the substrate. Alternatively, a thin metal layer (e.g., a copper, gold, silver, or aluminum film), a plastic film, or a slide can be used. This allows the substrate to have even greater flexibility. The anode layer A is made of a material that can obtain a nearly (substantially) transparent film. Since at least one of the two electrodes must be (substantially) transparent to allow light emission from the OLED, one of the anode layer A or the cathode layer C is transparent. Preferably, the anode layer A contains a high content of a transparent conductive oxide (TCO), or even consists of a TCO. Such an anode layer A can be made of, for example, indium tin oxide, aluminum zinc oxide, fluorine-doped tin oxide, indium zinc oxide, PbO, SnO, zirconium oxide, molybdenum oxide, vanadium oxide, tungsten oxide, graphite, doped Si, doped Ge, doped Ga, or the like. It may also include As, doped polyaniline, doped polypyrrole, and / or doped polythiophene.

[0505] The anode layer A is (substantially) indium tin oxide (ITO) (e.g., (InO3) 0.9 (SnO2) 0.1 The roughness of the anode layer A, which is made of a transparent conductive oxide (TCO), can be complemented by the use of a hole injection layer (HIL). The HIL also facilitates the injection of quasi-charge carriers (i.e., holes) in that it facilitates quasi-charge carrier transport from the TCO to the hole transport layer (HTL). The hole injection layer (HIL) may also contain poly-3,4-ethylenedioxythiophene (PEDOT), polystyrene sulfonate (PSS), MoO2, VO5, CuPC, or CuI, specifically a mixture of PEDOT and PSS. The hole injection layer (HIL) may also prevent metal diffusion from the anode layer A into the hole transport layer (HTL). HILs include, for example, PEDOT:poly-3,4-ethylenedioxythiophene:polystyrene sulfonate (PSS), poly-3,4-ethylenedioxythiophene (PEDOT), 4,4′,4″-tris[phenyl(m-toluyl)amino]triphenylamine (mMTDATA), 2,2′,7,7′-tetrakis(n,n-diphenylamino)-9,9′-spirobifluorene (spiro-TAD), N1,N1′-(biphenyl-4,4′-di)bis(N1-phenyl-N4,N4-di-m-toluylbenzene-1,4-diamine (DNTPD), N,N′-bis(1-naphthyl)-(4,4′-diphenyl ... phthalenyl)-N,N'-bis-phenyl-(1,1'-biphenyl)-4,4'-diamine (NPB), N,N'-diphenyl-N,N'-di-[4-(N,N-diphenyl-amino)phenyl]benzidine (NPNPB), N,N,N',N'-tetrakis(4-methoxyphenyl)benzidine (MeO-TPD), 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) and / or N,N'-diphenyl-N,N'-bis-(1-naphthyl)-9,9'-spirobifluorene-2,7-diamine (spiro-NPD).

[0506] Generally, the hole transport layer (HTL) is located adjacent to the anode layer A or the hole injection layer (HIL). Any hole transport compound can be used here. For example, electron-rich heteroaromatic compounds such as triarylamines and / or carbazoles can be used as hole transport compounds. The HTL can reduce the energy barrier between the anode layer A and the light-emitting layer (EML). The hole transport layer (HTL) can also function as an electron blocking layer (EBL). Preferably, the hole transport compound has a triplet state T1 with a relatively high energy level. For example, the hole transport layer (HTL) can be made of tris(4-carbazolyl-9-ylphenyl)amine (TCTA), poly-TPD (poly(4-butylphenyl-diphenyl-amine)), poly(4-butylphenyl-diphenyl-amine) (α-NPD), 4,4′-cyclohexylidene-bis[N,N-bis(4-methylphenyl)benzenamine] (TAPC), 4,4′,4″-tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA), spiro-TAD, DNTPD, NPB, NPNPB, MeO-TPD, HAT-CN, and / or 9,9′-diphenyl-6-(9-phenyl-9H-carbazol-1-yl)phenylamine. The HTL may also contain star-shaped heterocycles such as (9H,9'H-3,3'-bicarbazole-3-yl)-9H,9'H-bicarbazole (trisPcz). The HTL may also contain a p-doped layer, which may be composed of an inorganic or organic dopant in an organic hole-transporting matrix. For example, transition metal oxides such as vanadium oxide, molybdenum oxide, or tungsten oxide may also be used as inorganic dopants. For example, tetrafluorotetracyanoquinodimethane (F4-TCNQ), copper pentafluorobenzoate (Cu(I)pFBz), or transition metal complexes may also be used as organic dopants.

[0507] EBLs include, for example, 1,3-bis(carbazol-9-yl)benzene (mCP), T These may also include CTA, 2-TNATA, 3,3-di(9H-carbazol-9-yl)biphenyl (mCBP), tris-Pcz, 9-(4-tert-butylphenyl)-3,6-bis(triphenylsilyl)-9H-carbazole (CzSi), and / or N,N'-dicarbazolyl-1,4-dimethylbenzene (DCB).

[0508] Generally, the light-emitting layer (EML) is located adjacent to the hole-transporting layer (HTL). The light-emitting layer (EML) contains at least one light-emitting molecule. Specifically, the EML contains at least one light-emitting molecule E according to the present invention. In one embodiment, the light-emitting layer contains only organic molecules according to the present invention. Generally, the EML further contains one or more host materials H. For example, the host material H may be 4,4'-bis-(N-carbazolyl)-biphenyl (CBP), mCP, mCBP, dibenzo[b,d]thiophen-2-yltriphenylsilane (Sif87), CzSi, dibenzo[b,d]thiophen-2-yl)diphenylsilane (Sif88), bis[2-(diphenylphosphino)phenyl]etheroxide (DPEPO), 9-[3-(dibenzofuran-2-yl)phenyl]-9H-carbazole, ... The host material H is generally selected from the group consisting of [benzothiophen-2-yl]phenyl]-9H-carbazole, 9-[3,5-bis(2-dibenzofuranyl)phenyl]-9H-carbazole, 9-[3,5-bis(2-dibenzothiophenyl)phenyl]-9H-carbazole, 2,4,6-tris(biphenyl-3-yl)-1,3,5-triazine (T2T), 2,4,6-tris(triphenyl-3-yl)-1,3,5-triazine (T3T), and / or 2,4,6-tris(9,9'-spirobifluoren-2-yl)-1,3,5-triazine (TST). The host material H should generally be selected to exhibit a first triplet (T1) and first singlet (S1) energy level that is energetically higher than the first triplet (T1) and first singlet (S1) energy levels of the organic molecule.

For example, electron-deficient compounds such as benzimidazole, pyridine, triazole, oxadiazole (e.g., 1,3,4-oxadiazole), phosphine oxide, and sulfone may be used. The electron transporter may also be a star-shaped heterocycle such as 1,3,5-tri(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl (TPBi).

The cathode layer C may, for example, comprise or consist of a metal (e.g., Al, Au, Ag, Pt, Cu, Zn, Ni, Fe, Pb, LiF, Ca, Ba, Mg, In, W, or Pd) or a metal alloy. For practical reasons, the cathode layer may also consist of a (substantially) non-transparent metal such as Mg, Ca, or Al.

[0618] Fabrication and properties of optoelectronic devices Optoelectronic devices such as OLED devices containing the organic molecules according to the present invention can also be fabricated via vacuum deposition. When a layer contains more than one compound, the weight percentage of one or more compounds is expressed as %. The total weight percentage value is 100%, so if no value is specified, the proportion of the compound is the same as the difference between the specified value and 100%.

[0619] Non-fully optimized OLEDs are characterized using standard methods by measuring electroluminescence spectra, and the external quantum efficiency (%) is calculated as a function of intensity using the light sensed by the photodiode and the current. The lifetime of the OLED device is extracted from the change in luminance while operating at a constant current density. The LT50 value corresponds to the time when the measured luminance is reduced to 50% of the initial luminance; similarly, LT80 corresponds to the time when the measured luminance is reduced to 80% of the initial luminance, and LT95 corresponds to the time when the measured luminance is reduced to 95% of the initial luminance.

[0620] An accelerated lifetime measurement is performed (e.g., applying an increased current density), e.g., 500 cd / m 2 In the present invention, the LT80 value is determined using the following formula:

[0621]

number

[0622] Here, L0 denotes the initial luminance at the applied current density. The value corresponds to the average of a number of pixels (typically 2-8) and the standard deviation among such pixels is provided.
