Abstract
Description
TECHNICAL FIELD
[0001] The invention relates to organic molecules in the form of oligomers comprising at least two structural units and the use of organic molecules in organic light emitting diodes (OLEDs) and in other optoelectronic devices. BACKGROUND
[0002] The use of organic molecules in optoelectronic devices is under intense development. SUMMARY
[0003] It was an objective of the present invention to provide organic molecules suitable for use in optoelectronic devices.
[0004] This objective was achieved by the present invention which provides a novel class of organic molecules.
[0005] According to the invention, the organic molecules are purely organic molecules, i.e. the organic molecules do not contain any metal ions in contrast to known metal complexes used in optoelectronic devices.
[0006] According to the present invention, the organic molecules exhibit an emission maximum in the blue spectral range, in the sky blue spectral range or in the green spectral range. In particular, the organic molecules exhibit an emission maximum between 420 nm and 520 nm, preferably between 440 nm and 495 nm, more preferably between 450 nm and 470 nm, or in particular the organic molecules exhibit an emission maximum below 560 nm, more preferably below 550 nm, even more preferably below 545 nm, or even below 540 nm. The emission maximum will typically be above 500 nm, more preferably above 510 nm, even more preferably above 515 nm, or even above 520 nm. In particular, the photoluminescence quantum yield of the organic molecules according to the invention is 50% or more. The use of the organic molecules according to the invention in optoelectronic devices, such as organic light emitting diodes (OLEDs), leads to a higher efficiency or a higher color purity (expressed by the full width at half maximum (FWHM) of the emission) of the optoelectronic devices. The corresponding OLEDs have a higher stability than OLEDs with known emitter materials and comparable color.
[0007] The organic molecules (or called "organic light emitting molecules") (oligomers) of the invention comprise or consist of a structure of formula I:

[0527] Whenever hydrogen (H) is mentioned herein, hydrogen (H) can also be replaced by deuterium at each occurrence.
[0528] It will be understood that when a molecular fragment is described as a substituent or otherwise attached to another moiety, its name can be written as if it were a fragment (e.g., naphthyl, dibenzofuranyl) or as if it were an entire molecule (e.g., naphthalene, dibenzofuran). As used herein, these different ways of specifying substituents or attached fragments are considered equivalent.
[0529] In one embodiment, the organic molecule according to the invention has an excited state lifetime of no more than 5 ps, no more than 2.5 ps, in particular no more than 2.0 ps, more preferably no more than 1.0 ps, or no more than 0.7 ps in a film of poly(methyl methacrylate) (PMMA) having 1 to 5 wt.-%, in particular having 2 wt.-%, of the organic molecule at room temperature.
[0530] In a further embodiment of the invention, the organic molecule according to the invention has an emission peak in the visible or the nearest ultraviolet range, i.e., in the range of wavelengths from 380 nm to 800 nm, and 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, even more preferably less than 0.15 eV, or even less than 0.12 eV in a film of poly(methyl methacrylate) (PMMA) having 1 to 5 wt.-%, in particular having 2 wt.-%, of the organic molecule at room temperature.
[0531] The orbital and excited state energies can also be determined by way of experimental methods. The highest occupied molecular orbital energy (E HOMO ) is determined via cyclic voltammetry with a precision of 0.1 eV by methods known to the person skilled in the art. The lowest unoccupied molecular orbital energy (E LUMO ) is calculated as E HOMO + E gap , wherein E gap is determined as follows: for host compounds, unless stated otherwise, the onset of the emission spectrum of a film having 10 wt.-% of the host in poly(methyl methacrylate) (PMMA) is used as E gap . For emitter molecules, E gap is determined as the energy at which the excitation and emission spectra of a film having 1 to 5 wt.-%, in particular having 2 wt.-%, of the emitter in PMMA cross. For organic molecules according to the invention, E gapThe energy at which the excitation spectrum and the emission spectrum of a film determined to have 1 to 5 wt.-%, in particular 2 wt.-%, of the organic molecule in PMMA cross.
[0532] The energy of the first excited triplet state T1 is determined by the onset of the emission spectrum at low temperature, typically at 77 K. For host compounds in which the first excited singlet state and the lowest triplet state differ in energy by > 0.4 eV, phosphorescence is usually visible in the steady state spectrum in 2-Me-THF. Thus, the triplet energy can be determined as the onset of the phosphorescence spectrum. For TADF emitter molecules, the energy of the first excited triplet state T1 is determined by the onset of the delayed emission spectrum at 77 K, measured in a film of PMMA with 1 to 5 wt.-%, in particular 2 wt.-%, of the emitter and in case of an organic molecule according to the application with 1 to 5 wt.-%, in particular 2 wt.-%, of the organic molecule according to the application, if not stated otherwise. For both host and emitter compounds, the energy of the first excited singlet state S1 is determined by the onset of the emission spectrum, measured in a film of PMMA with 10 wt.-% of the host or emitter compound and in case of an organic molecule according to the application with 1 to 5 wt.-%, in particular 2 wt.-%, of the organic molecule according to the application, if not stated otherwise.
[0533] The onset of the emission spectrum is determined by calculating the intersection of the tangent of the emission spectrum with the x-axis. The tangent of the emission spectrum is set at the high energy side of the emission band and at the point of half maximum of the maximum intensity of the emission spectrum.
[0534] A further aspect of the application relates to the use of an organic molecule according to the application in an optoelectronic device as luminescent emitter or as absorber and / or as host material and / or as electron transport material and / or as hole injection material and / or as hole blocking material.

[0576] In a further aspect, the invention relates to an optoelectronic device comprising an organic molecule as described herein or a composition of matter of the type described herein, more specifically in the form of a device selected from the group consisting of an organic light emitting diode (OLED), a light emitting electrochemical cell, an OLED sensor (more specifically, a gas and vapor sensor that is not hermetically externally isolated), an organic diode, an organic solar cell, an organic transistor, an organic field effect transistor, an organic laser and a down-conversion element.
[0577] 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.

[0580] When the optoelectronic device is an OLED, it may, for example, have the following layer structure:
[0581] 1. Substrate
[0582] 2. Anode layer, A
[0583] 3. Hole injection layer, HIL
[0584] 4. Hole transport layer, HTL
[0585] 5. Electron blocking layer, EBL

[0591] wherein the OLED comprises each layer selected from the group of HIL, HTL, EBL, HBL, ETL, and EIL, optionally only different layers can be merged, the OLED can comprise more than one layer of each layer type defined above.
[0592] Further, in one embodiment, the optoelectronic device can include one or more protective layers that protect the device from damage from exposure to harmful substances in the environment, including, for example, moisture, vapor, and / or gases.
[0593] In one embodiment of the invention, the optoelectronic device is an OLED having the following inverted layer structure:
[0594] 1. Substrate
[0595] 2. Cathode layer, C
[0596] 3. Electron injection layer, EIL
[0597] 4. Electron transport layer, ETL
[0598] 5. Hole blocking layer, HBL
[0599] 6. Emission layer, EML
[0600] 7. Electron blocking layer, EBL
[0601] 8. Hole transport layer, HTL
[0602] 9. Hole injection layer, HIL
[0603] 10. Anode layer, A,
[0604] wherein the OLED comprises each layer selected from the group of HIL, HTL, EBL, HBL, ETL, and EIL, optionally only different layers can be merged, the OLED can comprise more than one layer of each layer type defined above.
[0605] In one embodiment of the invention, the optoelectronic device is an OLED that can have a stacked architecture. In such an architecture, individual cells are stacked on top of one another as opposed to the typical arrangement where OLEDs are placed side by side. An OLED exhibiting a stacked architecture can produce mixed light, specifically, white light can be produced by stacking a blue OLED, a green OLED, and a red OLED. Further, an OLED exhibiting a stacked architecture can include a charge generation layer (CGL) that is typically positioned between two OLED sub-cells and is typically composed of an n-doped layer and a p-doped layer and the n-doped layer of one CGL is typically positioned close to the anode layer.
[0606] In one embodiment of the invention, the optoelectronic device is an OLED comprising two or more emission layers between an anode and a cathode. In particular, such a so-called tandem OLED comprises three emission layers, wherein one emission layer emits red light, one emission layer emits green light, and one emission layer emits blue light, and optionally can further comprise layers such as charge generation layers, blocking layers or transport layers between the individual emission layers. In a further embodiment, the emission layers are stacked adjacently. In a further embodiment, the tandem OLED comprises a charge generation layer between each two emission layers. Additionally, adjacent emission layers or emission layers separated by a charge generation layer can be combined.
[0607] The substrate can be formed of any material or combination of materials. Most commonly, a glass slide is used as the substrate. Alternatively, a thin metal layer (e.g. a copper, gold, silver or aluminium film) or a plastic film or slide can be used. This can allow a higher degree of flexibility. The anode layer (A) is mainly composed of a material which allows to obtain a (substantially) transparent film. Since at least one of the two electrodes should be (substantially) transparent to allow light to be emitted from the OLED, either the anode layer (A) or the cathode layer (C) is transparent. Preferably, the anode layer (A) comprises a large amount of, or even consists of, a transparent conductive oxide (TCO). Such an anode layer (A) can for example comprise indium tin oxide, aluminium 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 GaAs, doped polyaniline, doped polypyrrole and / or doped polythiophene.
[0608] The anode layer (A) can (substantially) consist of indium tin oxide (ITO) (e.g. (In03) 80% - (Sn02) 20%). 0.9 (Sn02) 0.1) composition. The roughness of the anode layer (A) caused by the transparent conductive oxide (TCO) can be compensated by using a hole injection layer (HIL). Furthermore, the HIL can facilitate the injection of quasi-charge carriers (i.e., holes) because the transport of quasi-charge carriers from the TCO to the hole transport layer (HTL) is facilitated. The hole injection layer (HIL) can include poly(3,4-ethylenedioxythiophene) (PEDOT), polystyrene sulfonate (PSS), Mo02, V205, CuPC, or Cul (in particular, a mixture of PEDOT and PSS). The hole injection layer (HIL) can also prevent the diffusion of metal from the anode layer (A) into the hole transport layer (HTL). The HIL can include, for example, PEDOT:PSS (poly(3,4-ethylenedioxythiophene):polystyrene sulfonate), PEDOT (poly(3,4-ethylenedioxythiophene)), mMTDATA (4,4',4"-tris[phenyl(m-tolyl)amino]triphenylamine), Spiro-TAD (2,2',7,7'-tetrakis(n,n-diphenylamino)-9,9'-spirobifluorene), DNTPD (N1,N1'-(biphenyl-4,4'-diyl)bis(N1-phenyl-N4,N4-di-m-tolylbenzene-1,4-diamine)), NPB (N,N'-bis(1-naphthyl)-N,N'-bis-phenyl-(1,1'-biphenyl)-4,4'-diamine), NPNPB (N,N'-diphenyl-N,N'-di-[4-(N,N-diphenyl-amino)phenyl]phenylamine), MeO-TPD (N,N,N',N'-tetra(4-methoxyphenyl)phenylamine), HAT-CN (2,3,6,7,10,11-hexacyano-1,4,5,8,9,12-hexaazatriphenylene), and / or Spiro-NPD (N,N'-diphenyl-N,N'-bis(1-naphthyl)-9,9'-spirobifluorene-2,7-diamine).
[0609] Adjacent to the anode layer (A) or the hole injection layer (HIL), typically a hole transport layer (HTL) is positioned. Here, any hole transport compound can be used. For example, electron-rich heteroaromatic compounds such as triarylamines and / or carbazoles can be used as hole transport compounds. The HTL can lower the energy barrier between the anode layer (A) and the emission layer (EML). The hole transport layer (HTL) can also be an electron blocking layer (EBL). Preferably, the hole transport compound has a rather high energy level of its triplet state T1. For example, the hole transport layer (HTL) can comprise star-shaped heterocycles such as tris(4-carbazoyl-9-ylphenyl)amine (TCTA), poly-TPD (poly(4-butylphenyl-diphenyl-amine)), a-NPD (2,2'-dimethyl-N,N'-di-[(1-naphthyl)-N,N'-diphenyl]-1,1'-biphenyl-4,4'-diamine), TAPC (4,4'-cyclohexyl-diphenyl-[4-(phenyl-phenyl-amino)-phenyl]-amine), 2-TNATA (4,4',4"-tris[2-naphthyl(phenyl)amino]triphenylamine), Spiro-TAD, DNTPD, NPB, NPNPB, MeO-TPD, HAT-CN, and / or Tris-Pcz (9,9'-diphenyl-6-(9-phenyl-9H-carbazol-3-yl)-9H,9'H-3,3'-bicarbazole). Additionally, the HTL can comprise a p-doped layer which can consist of inorganic or organic dopants in an organic hole transport matrix. Transition metal oxides such as vanadium oxide, molybdenum oxide or tungsten oxide can for example be used as inorganic dopants. Tetrafluorotetracyanoquinodimethane (F4-TCNQ), copper pentafluorobenzoate (Cu(I) pFBz) or transition metal complexes can for example be used as organic dopants.
[0610] The EBL can for example comprise mCP (1,3-bis(carbazol-9-yl)benzene), TCTA, 2-TNATA, mCBP (3,3-di(9H-carbazol-9-yl)biphenyl), Tris-Pcz, CzSi (9-(4-tert-butylphenyl)-3,6-bis(triphenylsilyl)-9H-carbazole), and / or DCB (N,N'-dicarbazolyl-1,4-dimethylbenzene).
[0611] Adjacent to the hole transport layer (HTL), typically a light-emitting layer (EML) is positioned. The light-emitting layer (EML) comprises at least one organic molecule. Specifically, the EML comprises at least one organic molecule (E) according to the invention. In one embodiment, the light-emitting layer comprises only organic molecules according to the invention. Typically, the EML additionally comprises one or more host materials (H). For example, the host material (H) is selected from CBP (4,4'-bis(N-carbazolyl)biphenyl), mCP, mCBP, Sif87 (dibenzo[b,d]thiophene-2-yltriphenylsilane), CzSi, Sif88 (dibenzo[b,d]thiophene-2- yldiphenylsilane), DPEPO (bis[2-(diphenylphosphino)phenyl]ether oxide), 9-[3-(dibenzo- furan-2-yl)phenyl]-9H-carbazole, 9-[3-(dibenzo-thiophene-2-yl)phenyl]-9H-carbazole, 9-[3,5- bis(2-dibenzo-furan-yl)phenyl]-9H-carbazole, 9-[3,5-bis(2-dibenzo-thiophene-yl)phenyl]-9H- carbazole, T2T (2,4,6-tris(biphenyl-3-yl)-1,3,5-triazine), T3T (2,4,6-tris(terphenyl-3-yl)-1,3,5- triazine) and / or TST (2,4,6-tris(9,9'-spirobifluorene-2-yl)-1,3,5-triazine). The host material (H) should typically be selected to exhibit a first triplet (T1 ) and a first singlet (S1 ) energy level energetically higher than the first triplet (T1 ) and the first singlet (S1 ) energy level of the organic molecule.
[0612] In one embodiment of the application, the EML comprises a so-called mixed host system with at least one hole-dominant host and one electron-dominant host. In a specific embodiment, the EML comprises exactly one organic molecule according to the application and a mixed host system comprising T2T as electron-dominant host and a host selected from CBP, mCP, mCBP, 9-[3-(dibenzofuran-2-yl)phenyl]-9H-carbazole, 9-[3-(dibenzothiophene-2-yl)phenyl]-9H-carbazole, 9-[3,5-bis(2-dibenzofuranyl)phenyl]-9H-carbazole and 9-[3,5-bis(2-dibenzothiophenyl)phenyl]-9H-carbazole as hole-dominant host. In a further embodiment, the EML comprises 50 to 80 wt.-% (preferably 60 to 75 wt.-%) of a host selected from CBP, mCP, mCBP, 9-[3-(dibenzofuran-2-yl)phenyl]-9H-carbazole, 9-[3-(dibenzothiophene-2-yl)phenyl]-9H-carbazole, 9-[3,5-bis(2-dibenzofuranyl)phenyl]-9H-carbazole and 9-[3,5-bis(2-dibenzothiophenyl)phenyl]-9H-carbazole, 10 to 45 wt.-% (preferably 15 to 30 wt.-%) of T2T and 5 to 40 wt.-% (preferably 10 to 30 wt.-%) of the organic molecule according to the application.
[0613] Adjacent to the light-emitting layer (EML), an electron-transporting layer (ETL) can be positioned. Here, any electron-transporting agent can be used. Illustratively, electron-impoverished compounds such as benzimidazoles, pyridines, triazoles, oxadiazoles (e.g., 1,3,4-oxadiazole), phosphine oxides and sulfones can be used. The electron-transporting body can also be a star-shaped heterocycle such as 1,3,5-tris(1-phenyl-1H-benzo[d]imidazol-2-yl)benzene (TPBi). The ETL can comprise NBphen (2,9-bis(naphthalen-2-yl)-4,7-diphenyl-1,10-phenanthroline), Alq3 (tris(8-hydroxyquinoline)aluminum), TSPO1 (diphenyl-4-triphenylsilylphenyl-phosphine oxide), BPyTP2 (2,7-bis(2,2'-bipyridin-5-yl)triphenylene), Sif87 (dibenzo[b,d]thiophene-2-yltriphenylsilane), Sif88 (dibenzo[b,d]thiophene-2-yl-diphenylsilane), BmPyPhB (1,3-bis[3,5-di(pyridin-3-yl)phenyl]benzene) and / or BTB (4,4'-bis[2-(4,6-diphenyl-1,3,5-triazinyl)]-1,1'-biphenyl). Optionally, the ETL can be doped with a material such as Liq. The electron-transporting layer (ETL) can also block holes, or a hole-blocking layer (HBL) is introduced.

[0615] Adjacent to the electron transport layer (ETL), a cathode layer (C) can be positioned. The cathode layer (C) can 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 can also consist of a (substantially) non-transparent metal such as Mg, Ca or Al. Optionally or additionally, the cathode layer (C) can also comprise graphite and / or carbon nanotubes (CNT). Optionally, the cathode layer (C) can also consist of nanoscale silver wires.

[0617] Optionally, the electron transport layer (ETL) and / or the hole blocking layer (HBL) can also comprise one or more host compounds (H).
[0618] For further modifying the emission spectrum and / or the absorption spectrum of the light-emitting layer (EML), the light-emitting layer EML can further comprise one or more further emitter molecules (F). Such emitter molecules (F) can be any emitter molecule known in the art. Preferably, such emitter molecules (F) are molecules having a structure different from the structure of the organic molecules (E) according to the application. The emitter molecules (F) can optionally be TADF emitters. Optionally, the emitter molecules (F) can optionally be fluorescent and / or phosphorescent emitter molecules capable of shifting the emission spectrum and / or the absorption spectrum of the light-emitting layer (EML). Exemplarily, by emitting light typically red-shifted compared to the light emitted by the organic molecules, triplet and / or singlet excitons can be transferred from the organic molecules according to the application to the emitter molecules (F) before relaxing to the ground state (S0). Optionally, the emitter molecules (F) can also cause a two-photon effect (i.e. the absorption of two photons for the energy of half of the absorption maximum).
[0619] Optionally, the optoelectronic device (e.g. OLED) can for example be a substantially white optoelectronic device. For example, such white optoelectronic device can comprise at least one (deep) blue emitter molecule and one or more emitter molecules emitting green and / or red light. Then, energy transmittance can also optionally exist between two or more molecules as described above.
[0620] As used herein, the designation of the color of emitted and / or absorbed light is as follows, if not more specifically defined in the particular context:
[0621] Violet: wavelength range > 380 nm to 420 nm;
[0622] Deep blue: wavelength range > 420 nm to 480 nm;

[0632] Yet another aspect of the present application relates to an OLED emitting light at different color points. According to the present application, the OLED emits light having a narrow emission band (small full width at half maximum (FWHM)). In one aspect, the OLED according to the application emits light having a FWHM of the main emission peak of less than 0.25 eV (preferably less than 0.20 eV, more preferably less than 0.17 eV, even more preferably less than 0.15 eV, or even less than 0.13 eV).

In this context, the term "close to" refers to the range of CIEx and CIEy coordinates provided at the end of this paragraph. In commercial applications, typically top-emitting (the top electrode is transparent) devices are used, while the test devices used throughout this application represent bottom-emitting devices (the bottom electrode and the substrate are transparent).

[0637] In yet another aspect, the invention relates to a method for fabricating an optoelectronic component. In this case, the inventive organic molecules are used.
[0638] The optoelectronic devices according to the present application (in particular OLEDs) can be fabricated by any means of gas phase deposition and / or liquid handling. Thus, at least one layer:
[0639] - is prepared by way of a sublimation process,
[0640] - is prepared by way of an organic vapour phase deposition process,
[0641] - is prepared by way of a carrier gas sublimation process,
[0642] - is solution-processed or printed.
[0643] The method for fabricating optoelectronic devices (in particular OLEDs) according to the present application is known in the art. By way of subsequent deposition processes, different layers are deposited individually and successively on a suitable substrate. The individual layers can be deposited using the same or different deposition methods.
[0644] Gas phase deposition processes include, for example, thermal (co-)evaporation, chemical vapour deposition and physical vapour deposition. For active matrix OLED displays, an AMOLED backplane is used as a substrate. The individual layers can be processed from solutions or dispersions using appropriate solvents. Solution deposition processes include, for example, spin coating, dip coating and jet printing. Liquid handling can optionally be carried out in an inert atmosphere (for example, in a nitrogen atmosphere), and the solvent can be completely or partially removed by means known in the art.

[0789] Manufacture and characterization of optoelectronic devices
[0790] The optoelectronic devices (such as OLED devices) comprising the organic molecules according to the application can be manufactured via vacuum deposition methods. If the layer comprises more than one compound, the weight percentage of one or more compounds is given in %. The total weight percentage value is 100%, so if no value is given, the fraction of this compound is equal to the difference between the given value and 100%.
[0791] The OLEDs, which are not fully optimized, are characterized using standard methods and measuring electroluminescence spectra, intensity dependent external quantum efficiency in % which is calculated using light detected by a photodiode and current. OLED device lifetime is extracted from changes in luminance during operation at constant current density. The LT50 value corresponds to the time at which the measured luminance decreases to 50% of the initial luminance, similarly, the LT80 corresponds to the point in time at which the measured luminance decreases to 80% of the initial luminance, the LT95 corresponds to the point in time at which the measured luminance decreases to 95% of the initial luminance, etc.
[0792] Accelerated lifetime measurements are performed (e.g., applying increased current density). For example, the LT80 value at 500 cd / m 2 is determined using the following equation:
[0793]
[0794] where L0represents the initial luminance at the applied current density.
