Title: Organic electroluminescent apparatus

Description:
The present invention relates to an organic electroluminescent device comprising a mixture comprising an electron-transporting host material and a hole-transporting host material, and to a formulation comprising a mixture of the host materials and to a mixture comprising the host materials. The electron-transporting host material corresponds to a compound of the formula (1) from the class of dibenzofuran or dibenzothiophene derivatives containing a substituted pyridine, pyrimidine or triazine unit and a substituted further dibenzofuran or dibenzothiophene unit. 
     The structure of organic electroluminescent devices (e.g. OLEDs—organic light-emitting diodes or OLECs—organic light-emitting electrochemical cells) in which organic semiconductors are used as functional materials has long been known. Emitting materials used here, aside from fluorescent emitters, are increasingly organometallic complexes which exhibit phosphorescence rather than fluorescence. For quantum-mechanical reasons, up to a fourfold increase in energy efficiency and power efficiency is possible using organometallic compounds as phosphorescent emitters. In general terms, however, there is still a need for improvement in OLEDs, especially also in OLEDs which exhibit triplet emission (phosphorescence), for example with regard to efficiency, operating voltage and lifetime. 
     The properties of organic electroluminescent devices are not only determined by the emitters used. Also of particular significance here are especially the other materials used, such as host and matrix materials, hole blocker materials, electron transport materials, hole transport materials and electron or exciton blocker materials, and among these especially the host or matrix materials. Improvements to these materials can lead to distinct improvements to electroluminescent devices. 
     Host materials for use in organic electronic devices are well known to the person skilled in the art. The term “matrix material” is also frequently used in the prior art when what is meant is a host material for phosphorescent emitters. This use of the term is also applicable to the present invention. In the meantime, a multitude of host materials has been developed both for fluorescent and for phosphorescent electronic devices. 
     A further means of improving the performance data of electronic devices, especially of organic electroluminescent devices, is to use combinations of two or more materials, especially host materials or matrix materials. 
     U.S. Pat. No. 6,392,250 B1 discloses the use of a mixture consisting of an electron transport material, a hole transport material and a fluorescent emitter in the emission layer of an OLED. With the aid of this mixture, it was possible to improve the lifetime of the OLED compared to the prior art. 
     U.S. Pat. No. 6,803,720 B1 discloses the use of a mixture comprising a phosphorescent emitter and a hole transport material and an electron transport material in the emission layer of an OLED. Both the hole transport material and the electron transport material are small organic molecules.

The carbazole derivative is bonded directly via the nitrogen atom or via a linker in the 6 position of the dibenzofuran/dibenzothiophene. It is further reported that these materials can be mixed with a biscarbazole H2 in a ratio of 10:90 to 90:10.

     WO2020022860 describes organic light-emitting devices containing, in the emitting layer, a deuterated triazine derivative and a biscarbazole derivative. 
     However, there is still need for improvement in the case of use of these materials or in the case of use of mixtures of the materials, especially in relation to efficiency, operating voltage and/or lifetime of the organic electroluminescent device. 
     The problem addressed by the present invention is therefore that of providing a combination of host materials which are suitable for use in an organic electroluminescent device, especially in a fluorescent or phosphorescent OLED, and lead to good device properties, especially with regard to an improved lifetime, and that of providing the corresponding electroluminescent device. 
     It has now been found that this problem is solved, and the disadvantages from the prior art are eliminated, by the combination of at least one compound of the formula (1) as first host material and at least one hole-transporting compound of the formula (2) as second host material in a light-emitting layer of an organic electroluminescent device. The use of such a material combination for production of the light-emitting layer in an organic electroluminescent device leads to very good properties of these devices, especially with regard to lifetime, especially with equal or improved efficiency and/or operating voltage. The advantages are especially also manifested in the presence of a light-emitting component in the emission layer, especially in the case of combination with emitters of the formula (III), at concentrations between 2% and 15% by weight. 
     The present invention therefore first provides an organic electroluminescent device comprising an anode, a cathode and at least one organic layer, containing at least one light-emitting layer, wherein the at least one light-emitting layer contains at least one compound of the formula (1) as host material 1 and at least one compound of the formula (2) as host material 2

The corresponding preferred embodiments as described hereinafter likewise form part of the subject-matter of the present invention. The surprising and advantageous effects are achieved through specific selection of the compounds of the formula (1) and the compounds of the formula (2). 
     The organic electroluminescent device of the invention is, for example, an organic light-emitting transistor (OLET), an organic field quench device (OFQD), an organic light-emitting electrochemical cell (OLEC, LEC, LEEC), an organic laser diode (0-laser) or an organic light-emitting diode (OLED). The organic electroluminescent device of the invention is especially an organic light-emitting diode or an organic light-emitting electrochemical cell. The device of the invention is more preferably an OLED. 
     The organic layer of the device of the invention that contains the light-emitting layer containing the material combination of at least one compound of the formula (1) and at least one compound of the formula (2), as described above or described hereinafter, preferably comprises, in addition to this light-emitting layer (EML), a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), an electron injection layer (EIL) and/or a hole blocker layer (HBL). It is also possible for the device of the invention to include multiple layers from this group selected from EML, HIL, HTL, ETL, EIL and HBL. 
     However, the device may also comprise inorganic materials or else layers formed entirely from inorganic materials. 
     It is preferable that the light-emitting layer containing at least one compound of the formula (1) and at least one compound of the formula (2) is a phosphorescent layer which is characterized in that it comprises, in addition to the host material combination of the compounds of the formula (1) and formula (2), as described above, at least one phosphorescent emitter. A suitable selection of emitters and preferred emitters is described hereinafter. 
     An aryl group in the context of this invention contains 6 to 40 aromatic ring atoms, preferably carbon atoms. A heteroaryl group in the context of this invention contains 5 to 40 aromatic ring atoms, where the ring atoms include carbon atoms and at least one heteroatom, with the proviso that the sum total of carbon atoms and heteroatoms adds up to at least 5. The heteroatoms are preferably selected from N, O and/or S. An aryl group or heteroaryl group is understood here to mean either a simple aromatic cycle, i.e. phenyl, derived from benzene, or a simple heteroaromatic cycle, for example derived from pyridine, pyrimidine or thiophene, or a fused aryl or heteroaryl group, for example derived from naphthalene, anthracene, phenanthrene, quinoline or isoquinoline. An aryl group having 6 to 18 carbon atoms is therefore preferably phenyl, naphthyl, phenanthryl or triphenylenyl, with no restriction in the attachment of the aryl group as substituent. The aryl or heteroaryl group in the context of this invention may bear one or more R radicals, where the substituent R is described below.

The heteroatoms in the heteroaromatic ring system are preferably selected from N, O and/or S.

For example, systems such as 9,9′-spirobifluorene, 9,9-diarylfluorene, triarylamine, diaryl ethers, stilbene, etc. shall thus also be regarded as aromatic or heteroaromatic ring systems in the context of this invention, and likewise systems in which two or more aryl groups are interrupted, for example, by a linear or cyclic alkyl group or by a silyl group. In addition, systems in which two or more aryl or heteroaryl groups are bonded directly to one another, for example biphenyl, terphenyl, quaterphenyl or bipyridine, are likewise encompassed by the definition of the aromatic or heteroaromatic ring system.

     The concentration of the electron-transporting host material of the formula (1) as described above or described as preferred in the mixture of the invention or in the light-emitting layer of the device of the invention is in the range from 5% by weight to 90% by weight, preferably in the range from 10% by weight to 85% by weight, more preferably in the range from 20% by weight to 85% by weight, even more preferably in the range from 30% by weight to 80% by weight, very especially preferably in the range from 20% by weight to 60% by weight and most preferably in the range from 30% by weight to 50% by weight, based on the overall mixture or based on the overall composition of the light-emitting layer. 
     The concentration of the hole-transporting host material of the formula (2) as described above or described as preferred in the mixture of the invention or in the light-emitting layer of the device of the invention is in the range from 10% by weight to 95% by weight, preferably in the range from 15% by weight to 90% by weight, more preferably in the range from 15% by weight to 80% by weight, even more preferably in the range from 20% by weight to 70% by weight, very especially preferably in the range from 40% by weight to 80% by weight and most preferably in the range from 50% by weight to 70% by weight, based on the overall mixture or based on the overall composition of the light-emitting layer. 
     The present invention also relates to a mixture which, as well as the aforementioned host materials 1 and 2, as described above or described with preference, especially mixtures M1 to M1134, also contains at least one phosphorescent emitter. 
     The present invention also relates to an organic electroluminescent device as described above or described with preference, wherein the light-emitting layer, as well as the aforementioned host materials 1 and 2, as described above or described with preference, especially material combinations M1 to M1134, also comprises at least one phosphorescent emitter. 
     The term “phosphorescent emitters” typically encompasses compounds where the light is emitted through a spin-forbidden transition from an excited state having higher spin multiplicity, i.e. a spin state &gt;1, for example through a transition from a triplet state or a state having an even higher spin quantum number, for example a quintet state. This is preferably understood to mean a transition from a triplet state. 
     Suitable phosphorescent emitters (=triplet emitters) are especially compounds which, when suitably excited, emit light, preferably in the visible region, and also contain at least one atom of atomic number greater than 20, preferably greater than 38 and less than 84, more preferably greater than 56 and less than 80, especially a metal having this atomic number. Preferred phosphorescence emitters used are compounds containing copper, molybdenum, tungsten, rhenium, ruthenium, osmium, rhodium, iridium, palladium, platinum, silver, gold or europium, especially compounds containing iridium or platinum. In the context of the present invention, all luminescent compounds containing the abovementioned metals are regarded as phosphorescent emitters. 
     In general, all phosphorescent complexes as used for phosphorescent OLEDs according to the prior art and as known to those skilled in the art in the field of organic electroluminescent devices are suitable.

a compound of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or a compound from table 6 or 7. 
     The light-emitting layer in the organic electroluminescent device of the invention, comprising at least one phosphorescent emitter, is preferably an infrared-emitting or yellow-, orange-, red-, green-, blue- or ultraviolet-emitting layer, more preferably a yellow- or green-emitting layer and most preferably a green-emitting layer. 
     A yellow-emitting layer is understood here to mean a layer having a photoluminescence maximum within the range from 540 to 570 nm. An orange-emitting layer is understood to mean a layer having a photoluminescence maximum within the range from 570 to 600 nm. A red-emitting layer is understood to mean a layer having a photoluminescence maximum within the range from 600 to 750 nm. A green-emitting layer is understood to mean a layer having a photoluminescence maximum within the range from 490 to 540 nm. A blue-emitting layer is understood to mean a layer having a photoluminescence maximum within the range from 440 to 490 nm. The photoluminescence maximum of the layer is determined here by measuring the photoluminescence spectrum of the layer having a layer thickness of 50 nm at room temperature, said layer having the inventive combination of the host materials of the formulae (1) and (2) and the appropriate emitter. 
     The photoluminescence spectrum of the layer is recorded, for example, with a commercial photoluminescence spectrometer. 
     The photoluminescence spectrum of the emitter chosen is generally measured in oxygen-free solution, 10 −5  molar, at room temperature, a suitable solvent being any in which the chosen emitter dissolves in the concentration mentioned. Particularly suitable solvents are typically toluene or 2-methyl-THF, but also dichloromethane. Measurement is effected with a commercial photoluminescence spectrometer. The triplet energy T1 in eV is determined from the photoluminescence spectra of the emitters. Firstly, the peak maximum Plmax. (in nm) of the photoluminescence spectrum is determined. The peak maximum Plmax. (in nm) is then converted to eV by: E(T1 in eV)=1240/E(T1 in nm)=1240/PLmax. (in nm). 
     Preferred phosphorescent emitters are accordingly infrared emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜1.9 eV to ˜1.0 eV. 
     Preferred phosphorescent emitters are accordingly red emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜2.1 eV to ˜1.9 eV. 
     Preferred phosphorescent emitters are accordingly yellow emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜2.3 eV to ˜2.1 eV. 
     Preferred phosphorescent emitters are accordingly green emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜2.5 eV to ˜2.3 eV. 
     Preferred phosphorescent emitters are accordingly blue emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜3.1 eV to ˜2.5 eV. 
     Preferred phosphorescent emitters are accordingly ultraviolet emitters of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜4.0 eV to ˜3.1 eV. 
     Particularly preferred phosphorescent emitters are accordingly green or yellow emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7 as described above. 
     Very particularly preferred phosphorescent emitters are accordingly green emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, the triplet energy T 1  of which is preferably ˜2.5 eV to ˜2.3 eV. 
     Most preferably, green emitters, preferably of the formula (III), (Ia), (IIa), (IIIa), (IVa), (Va), (VIa) or from table 6 or 7, as described above, are selected for the composition of the invention or emitting layer of the invention. 
     It is also possible for fluorescent emitters to be present in the light-emitting layer of the device of the invention. 
     Preferred fluorescent emitters are selected from the class of the arylamines. An arylamine or an aromatic amine in the context of this invention is understood to mean a compound containing three substituted or unsubstituted aromatic or heteroaromatic ring systems bonded directly to the nitrogen. Preferably, at least one of these aromatic or heteroaromatic ring systems is a fused ring system, more preferably having at least 14 aromatic ring atoms. Preferred examples of these are aromatic anthraceneamines, aromatic anthracenediamines, aromatic pyreneamines, aromatic pyrenediamines, aromatic chryseneamines or aromatic chrysenediamines. An aromatic anthraceneamine is understood to mean a compound in which a diarylamino group is bonded directly to an anthracene group, preferably in the 9 position. An aromatic anthracenediamine is understood to mean a compound in which two diarylamino groups are bonded directly to an anthracene group, preferably in the 9, 10 positions. Aromatic pyreneamines, pyrenediamines, chryseneamines and chrysenediamines are defined analogously, where the diarylamino groups are bonded to the pyrene preferably in the 1 position or 1,6 position. Further preferred fluorescent emitters are indenofluoreneamines or -diamines, for example according to WO 2006/108497 or WO 2006/122630, benzoindenofluoreneamines or -diamines, for example according to WO 2008/006449, and dibenzoindenofluoreneamines or -diamines, for example according to WO 2007/140847, and the indenofluorene derivatives having fused aryl groups disclosed in WO 2010/012328. 
     In a further preferred embodiment of the invention, the at least one light-emitting layer of the organic electroluminescent device, as well as the host materials 1 and 2, as described above or described as preferred, may comprise further host materials or matrix materials, called mixed matrix systems. The mixed matrix systems preferably comprise three or four different matrix materials, more preferably three different matrix materials (in other words, one further matrix component in addition to the host materials 1 and 2, as described above). Particularly suitable matrix materials which can be used in combination as matrix component in a mixed matrix system are selected from wide-band gap materials, bipolar host materials, electron transport materials (ETM) and hole transport materials (HTM). 
     A wide-band gap material is understood herein to mean a material within the scope of the disclosure of U.S. Pat. No. 7,294,849 which is characterized by a band gap of at least 3.5 eV, the band gap being understood to mean the gap between the HOMO and LUMO energy of a material. 
     In one embodiment of the present invention, the mixture does not comprise any further constituents, i.e. functional materials, aside from the constituents of electron-transporting host material of the formula (1) and hole-transporting host material of the formula (2). These are material mixtures that are used as such for production of the light-emitting layer. These mixtures are also referred to as premix systems that are used as the sole material source in the vapour deposition of the host materials for the light-emitting layer and have a constant mixing ratio in the vapour deposition. In this way, it is possible in a simple and rapid manner to achieve the vapour deposition of a layer with homogeneous distribution of the components without the need for precise actuation of a multitude of material sources. 
     In an alternative embodiment of the present invention, the mixture also comprises the phosphorescent emitter, as described above, in addition to the constituents of electron-transporting host material of the formula (1) and hole-transporting host material of the formula (2). In the case of a suitable mixing ratio in the vapour deposition, this mixture may also be used as the sole material source, as described above. 
     The components or constituents of the light-emitting layer of the device of the invention may thus be processed by vapour deposition or from solution. The material combination of host materials 1 and 2, as described above or described as preferred, optionally with the phosphorescent emitter, as described above or described as preferred, are provided for the purpose in a formulation containing at least one solvent. These formulations may, for example, be solutions, dispersions or emulsions. For this purpose, it may be preferable to use mixtures of two or more solvents. 
     The present invention therefore further provides a formulation comprising an inventive mixture of host materials 1 and 2, as described above, optionally in combination with a phosphorescent emitter, as described above or described as preferred, and at least one solvent. 
     Suitable and preferred solvents are, for example, toluene, anisole, o-, m- or p-xylene, methyl benzoate, mesitylene, tetralin, veratrole, THF, methyl-THF, THP, chlorobenzene, dioxane, phenoxytoluene, especially 3-phenoxytoluene, (−)-fenchone, 1,2,3,5-tetramethylbenzene, 1,2,4,5-tetramethylbenzene, 1-methylnaphthalene, 2-methylbenzothiazole, 2-phenoxyethanol, 2-pyrrolidinone, 3-methylanisole, 4-methylanisole, 3,4-dimethylanisole, 3,5-dimethylanisole, acetophenone, α-terpineol, benzothiazole, butyl benzoate, cumene, cyclohexanol, cyclohexanone, cyclohexylbenzene, decalin, dodecylbenzene, ethyl benzoate, indane, methyl benzoate, NMP, p-cymene, phenetole, 1,4-diisopropylbenzene, dibenzyl ether, diethylene glycol butyl methyl ether, triethylene glycol butyl methyl ether, diethylene glycol dibutyl ether, triethylene glycol dimethyl ether, diethylene glycol monobutyl ether, tripropylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, 2-isopropylnaphthalene, pentylbenzene, hexylbenzene, heptylbenzene, octylbenzene, 1,1-bis(3,4-dimethylphenyl)ethane, hexamethylindane or mixtures of these solvents. 
     The formulation here may also comprise at least one further organic or inorganic compound which is likewise used in the light-emitting layer of the device of the invention, especially a further emitting compound and/or a further matrix material. 
     The light-emitting layer in the device of the invention, according to the preferred embodiments and the emitting compound, contains preferably between 99.9% and 1% by volume, further preferably between 99% and 10% by volume, especially preferably between 98% and 60% by volume, very especially preferably between 97% and 80% by volume, of matrix material composed of at least one compound of the formula (1) and at least one compound of the formula (2) according to the preferred embodiments, based on the overall composition of emitter and matrix material. Correspondingly, the light-emitting layer in the device of the invention preferably contains between 0.1% and 99% by volume, further preferably between 1% and 90% by volume, more preferably between 2% and 40% by volume, most preferably between 3% and 20% by volume, of the emitter based on the overall composition of the light-emitting layer composed of emitter and matrix material. If the compounds are processed from solution, preference is given to using the corresponding amounts in % by weight rather than the above-specified amounts in % by volume. 
     The light-emitting layer in the device of the invention, according to the preferred embodiments and the emitting compound, preferably contains the matrix material of the formula (1) and the matrix material of the formula (2) in a percentage by volume ratio between 3:1 and 1:3, preferably between 1:2.5 and 1:1, more preferably between 1:2 and 1:1. If the compounds are processed from solution, preference is given to using the corresponding ratio in % by weight rather than the above-specified ratio in % by volume. 
     The sequence of layers in the organic electroluminescent device of the invention is preferably as follows: 
     anode/hole injection layer/hole transport layer/emitting layer/electron transport layer/electron injection layer/cathode. 
     This sequence of the layers is a preferred sequence. 
     At the same time, it should be pointed out again that not all the layers mentioned need be present and/or that further layers may additionally be present. 
     The organic electroluminescent device of the invention may contain two or more emitting layers. At least one of the emitting layers is the light-emitting layer of the invention containing at least one compound of the formula (1) as host material 1 and at least one compound of the formula (2) as host material 2 as described above. More preferably, these emission layers in this case have several emission maxima between 380 nm and 750 nm overall, such that the overall result is white emission; in other words, various emitting compounds which may fluoresce or phosphoresce and which emit blue or yellow or orange or red light are used in the emitting layers. Especially preferred are three-layer systems, i.e. systems having three emitting layers, where the three layers show blue, green and orange or red emission (for the basic construction see, for example, WO 2005/011013). It should be noted that, for the production of white light, rather than a plurality of colour-emitting emitter compounds, an emitter compound used individually which emits over a broad wavelength range may also be suitable. 
     Suitable charge transport materials as usable in the hole injection or hole transport layer or electron blocker layer or in the electron transport layer of the organic electroluminescent device of the invention are, for example, the compounds disclosed in Y. Shirota et al., Chem. Rev. 2007, 107(4), 953-1010, or other materials as used in these layers according to the prior art. 
     Materials used for the electron transport layer may be any materials as used according to the prior art as electron transport materials in the electron transport layer. Especially suitable are aluminium complexes, for example Alq 3 , zirconium complexes, for example Zrq 4 , benzimidazole derivatives, triazine derivatives, pyrimidine derivatives, pyridine derivatives, pyrazine derivatives, quinoxaline derivatives, quinoline derivatives, oxadiazole derivatives, aromatic ketones, lactams, boranes, diazaphosphole derivatives and phosphine oxide derivatives. Further suitable materials are derivatives of the abovementioned compounds as disclosed in JP 2000/053957, WO 2003/060956, WO 2004/028217, WO 2004/080975 and WO 2010/072300. 
     Preferred hole transport materials are especially materials which can be used in a hole transport, hole injection or electron blocker layer, such as indenofluoreneamine derivatives (for example according to WO 06/122630 or WO 06/100896), the amine derivatives disclosed in EP 1661888, hexaazatriphenylene derivatives (for example according to WO 01/049806), amine derivatives having fused aromatic systems (for example according to U.S. Pat. No. 5,061,569), the amine derivatives disclosed in WO 95/09147, monobenzoindenofluoreneamines (for example according to WO 08/006449), dibenzoindenofluoreneamines (for example according to WO 07/140847), spirobifluoreneamines (for example according to WO 2012/034627 or the as yet unpublished EP 12000929.5), fluoreneamines (for example according to WO 2014/015937, WO 2014/015938 and WO 2014/015935), spirodibenzopyranamines (for example according to WO 2013/083216) and dihydroacridine derivatives (for example WO 2012/150001). 
     Suitable cathodes of the device of the invention are metals having a low work function, metal alloys or multilayer structures composed of various metals, for example alkaline earth metals, alkali metals, main group metals or lanthanoids (e.g. Ca, Ba, Mg, Al, In, Mg, Yb, Sm, etc.). Additionally suitable are alloys composed of an alkali metal or alkaline earth metal and silver, for example an alloy composed of magnesium and silver. In the case of multilayer structures, in addition to the metals mentioned, it is also possible to use further metals having a relatively high work function, for example Ag or Al, in which case combinations of the metals such as Ca/Ag, Mg/Ag or Ba/Ag, for example, are generally used. It may also be preferable to introduce a thin interlayer of a material having a high dielectric constant between a metallic cathode and the organic semiconductor. Examples of useful materials for this purpose are alkali metal or alkaline earth metal fluorides, but also the corresponding oxides or carbonates (e.g. LiF, Li 2 O, BaF 2 , MgO, NaF, CsF, Cs 2 CO 3 , etc.). It is also possible to use lithium quinolinate (LiQ) for this purpose. The layer thickness of this layer is preferably between 0.5 and 5 nm. 
     Preferred anodes are materials having a high work function. Preferably, the anode has a work function of greater than 4.5 eV versus vacuum. Firstly, metals having a high redox potential are suitable for this purpose, for example Ag, Pt or Au. Secondly, metal/metal oxide electrodes (e.g. Al/Ni/NiO x , Al/PtO x ) may also be preferred. For some applications, at least one of the electrodes has to be transparent or partly transparent in order to enable either the irradiation of the organic material (organic solar cell) or the emission of light (OLED, O-LASER). Preferred anode materials here are conductive mixed metal oxides. Particular preference is given to indium tin oxide (ITO) or indium zinc oxide (IZO). Preference is further given to conductive doped organic materials, especially conductive doped polymers. In addition, the anode may also consist of two or more layers, for example of an inner layer of ITO and an outer layer of a metal oxide, preferably tungsten oxide, molybdenum oxide or vanadium oxide. 
     The organic electroluminescent device of the invention, in the course of production, is appropriately (according to the application) structured, contact-connected and finally sealed, since the lifetime of the devices of the invention is shortened in the presence of water and/or air. 
     The production of the device of the invention is not restricted here. It is possible that one or more organic layers, including the light-emitting layer, are coated by a sublimation method. In this case, the materials are applied by vapour deposition in vacuum sublimation systems at an initial pressure of less than 10 −5  mbar, preferably less than 10 −6  mbar. In this case, however, it is also possible that the initial pressure is even lower, for example less than 10 −7  mbar. 
     The organic electroluminescent device of the invention is preferably characterized in that one or more layers are coated by the OVPD (organic vapour phase deposition) method or with the aid of a carrier gas sublimation. In this case, the materials are applied at a pressure between 10 −5  mbar and 1 bar. A special case of this method is the OVJP (organic vapour jet printing) method, in which the materials are applied directly by a nozzle and thus structured (for example, M. S. Arnold et al., Appl. Phys. Lett. 2008, 92, 053301). 
     The organic electroluminescent device of the invention is further preferably characterized in that one or more organic layers comprising the composition of the invention are produced from solution, for example by spin-coating, or by any printing method, for example screen printing, flexographic printing, nozzle printing or offset printing, but more preferably LITI (light-induced thermal imaging, thermal transfer printing) or inkjet printing. For this purpose, soluble host materials 1 and 2 and phosphorescent emitters are needed. Processing from solution has the advantage that, for example, the light-emitting layer can be applied in a very simple and inexpensive manner. This technique is especially suitable for the mass production of organic electroluminescent devices. 
     In addition, hybrid methods are possible, in which, for example, one or more layers are applied from solution and one or more further layers are applied by vapour deposition. 
     These methods are known in general terms to those skilled in the art and can be applied to organic electroluminescent devices. 
     The invention therefore further provides a process for producing the organic electroluminescent device of the invention as described above or described as preferred, characterized in that the light-emitting layer is applied by gas phase deposition, especially by a sublimation method and/or by an OVPD (organic vapour phase deposition) method and/or with the aid of a carrier gas sublimation, or from solution, especially by spin-coating or by a printing method. 
     In the case of production by means of gas phase deposition, there are in principle two ways in which the light-emitting layer of the invention can be applied or vapour-deposited onto any substrate or the prior layer. Firstly, the materials used can each be initially charged in a material source and ultimately evaporated from the different material sources (“co-evaporation”). Secondly, the various materials can be premixed (premix systems) and the mixture can be initially charged in a single material source from which it is ultimately evaporated (“premix evaporation”). In this way, it is possible in a simple and rapid manner to achieve the vapour deposition of the light-emitting layer with homogeneous distribution of the components without the need for precise actuation of a multitude of material sources. 
     The invention accordingly further provides a process for producing the device of the invention, characterized in that the at least one compound of the formula (1) as described above or described as preferred and the at least one compound of the formula (2) as described above or described as preferred are deposited from the gas phase successively or simultaneously from at least two material sources, optionally with the at least one phosphorescent emitter as described above or described as preferred, and form the light-emitting layer. 
     In a preferred embodiment of the present invention, the light-emitting layer is applied by means of gas phase deposition, wherein the constituents of the composition are premixed and evaporated from a single material source. 
     The invention accordingly further provides a process for producing the device of the invention, characterized in that the at least one compound of the formula (1) and the at least one compound of the formula (2) are deposited from the gas phase as a mixture, successively or simultaneously with the at least one phosphorescent emitter, and form the light-emitting layer. 
     The invention further provides a process for producing the device of the invention, as described above or described as preferred, characterized in that the at least one compound of the formula (1) and the at least one compound of the formula (2), as described above or described as preferred, are applied from solution together with the at least one phosphorescent emitter in order to form the light-emitting layer. 
     The devices of the invention feature the following surprising advantages over the prior art: 
     The use of the described material combination of host materials 1 and 2, as described above, especially leads to an increase in the lifetime of the devices. 
     As apparent in the example given hereinafter, it is possible to determine by comparison of the data for OLEDs with combinations from the prior art that the inventive combinations of matrix materials in the EML lead to devices having an increase in lifetime by about 19% to 65%, irrespective of the emitter concentration. 
     It should be pointed out that variations of the embodiments described in the present invention are covered by the scope of this invention. Any feature disclosed in the present invention may, unless this is explicitly ruled out, be exchanged for alternative features which serve the same purpose or an equivalent or similar purpose. Any feature disclosed in the present invention, unless stated otherwise, should therefore be considered as an example from a generic series or as an equivalent or similar feature. 
     All features of the present invention may be combined with one another in any manner, unless particular features and/or steps are mutually exclusive. This is especially true of preferred features of the present invention. Equally, features of non-essential combinations may be used separately (and not in combination). 
     The technical teaching disclosed with the present invention may be abstracted and combined with other examples. 
     The invention is illustrated in more detail by the examples which follow, without any intention of restricting it thereby. 
     General Methods: 
     In all quantum-chemical calculations, the Gaussian16 (Rev. B.01) software package is used. The neutral singlet ground state is optimized at the B3LYP/6-31G(d) level. HOMO and LUMO values are determined at the B3LYP/6-31G(d) level for the B3LYP/6-31G(d)-optimized ground state energy. Then TD-DFT singlet and triplet excitations (vertical excitations) are calculated by the same method (B3LYP/6-31G(d)) and with the optimized ground state geometry. The standard settings for SCF and gradient convergence are used. 
     From the energy calculation, the HOMO is obtained as the last orbital occupied by two electrons (alpha occ. eigenvalues) and LUMO as the first unoccupied orbital (alpha virt. eigenvalues) in Hartree units, where HEh and LEh represent the HOMO energy in Hartree units and the LUMO energy in Hartree units respectively. This is used to determine the HOMO and LUMO value in electron volts, calibrated by cyclic voltammetry measurements, as follows: 
     HOMOcorr=0.90603*HOMO−0.84836 
     LUMOcorr=0.99687*LUMO−0.72445 
     The triplet level T1 of a material is defined as the relative excitation energy (in eV) of the triplet state having the lowest energy which is found by the quantum-chemical energy calculation. 
     The singlet level S1 of a material is defined as the relative excitation energy (in eV) of the singlet state having the second-lowest energy which is found by the quantum-chemical energy calculation. 
     The energetically lowest singlet state is referred to as S0. 
     The method described herein is independent of the software package used and always gives the same results. Examples of frequently utilized programs for this purpose are “Gaussian09” (Gaussian Inc.) and Q-Chem 4.1 (Q-Chem, Inc.). In the present case, the energies are calculated using the software package “Gaussian16 (Rev. B.01)”. 
    
    
     EXAMPLE 1: PRODUCTION OF THE OLEDS 
     The examples which follow (see tables 8 to 10) present the use of the material combinations of the invention in OLEDs by comparison with material combinations from the prior art. 
     Pretreatment for examples V1 to V5 and E1a to E5g: Glass plates coated with structured ITO (indium tin oxide) of thickness 50 nm are treated prior to coating, first with an oxygen plasma, followed by an argon plasma. These plasma-treated glass plates form the substrates to which the OLEDs are applied. 
     The OLEDs basically have the following layer structure: substrate/hole injection layer (HIL)/hole transport layer (HTL)/electron blocker layer (EBL)/emission layer (EML)/optional hole blocker layer (HBL)/electron transport layer (ETL)/optional electron injection layer (EIL) and finally a cathode. The cathode is formed by an aluminium layer of thickness 100 nm. The exact structure of the OLEDs can be found in table 8. The materials required for production of the OLEDs, if they have not already been described before, are shown in table 10. The device data of the OLEDs are listed in table 9. 
     Examples V1 and V5 are comparative examples with a biscarbazole as hole-transporting host according to the prior art. 
     Examples E1a to E5f show data for OLEDs of the invention. 
     All materials are applied by thermal vapour deposition in a vacuum chamber. In this case, the emission layer always consists of at least two matrix materials and an emitting dopant (emitter) which is added to the matrix material(s) in a particular proportion by volume by co-evaporation. Details given in such a form as E13:BCbz1:TE2 (32%:60%:8%) mean here that the material E13 is present in the layer in a proportion by volume of 32%, BCbz1 in a proportion of 60% and TE2 in a proportion of 8%. Analogously, the electron transport layer may also consist of a mixture of two materials. 
     The electroluminescence spectra are determined at a luminance of 1000 cd/m 2 , and the CIE 1931 x and y colour coordinates are calculated therefrom. The parameter U10 in table 9 refers to the voltage which is required for a current density of 10 mA/cm 2 . SE10 and EQE10 respectively denote the current efficiency and external quantum efficiency that are attained at 10 mA/m 2 . 
     The lifetime LT is defined as the time after which luminance, measured in cd/m 2  in forward direction, drops from the starting luminance to a certain proportion L1 in the course of operation with constant current density jo. A figure of L1=80% in table 9 means that the lifetime reported in the LT column corresponds to the time after which luminance in cd/m 2  falls to 80% of its starting value. 
     Use of Mixtures of the Invention in OLEDs 
     The material combinations of the invention are used in examples E1a-k, E2a-h, E3a-g, E4a-j, E5a-g as matrix materials in the emission layer of green-phosphorescing OLEDs. As a comparison with the prior art, materials E7, E8, E13, E15, E18, BCbz1 to BCbz5 are used in examples V1 to V5. 
     On comparison of the inventive examples with the corresponding comparative examples, it is clearly apparent that the inventive examples each show a distinct advantage in device lifetime, with otherwise comparable performance data of the OLEDs.

     An initial charge of S1a (46.11 g, 88.0 mmol), bis(pinacolato)diboron [73183-34-3] (25.39 g, 100.0 mmol) and potassium acetate (28.82 g, 293.6 mmol) in 1,4-dioxane (700 ml) is inertized with argon for 2 min. Subsequently, XPhos [564483-18-7] (456 mg, 0.96 mmol) and Pd 2 (dba) 3 [51364-51-3] (435 mg, 0.48 mmol) are added and the reaction mixture is stirred under reflux for 26 h. After cooling, the solvent is removed by rotary evaporation and the residue is worked up by extraction with toluene/water. The organic phase is dried over Na 2 SO 4  and concentrated to dryness by rotary evaporation. The residue is boiled under reflux with ethyl acetate for 2 h, and the solids are filtered off with suction and washed with ethyl acetate. Yield: 49.4 g (80.2 mmol, 91%) of solids; 97% by  1 H NMR. 
     The following compounds can be prepared analogously: Rather than X-Phos, it is also possible to use S-Phos or tricyclohexylphosphine as ligand, or Pd(dppf)Cl 2  x CH 2 Cl 2  [95464-05-4] for borylation of functional bromide groups. Purification can be effected using column chromatography, or recrystallization can be effected using standard solvents such as ethanol, butanol, acetone, ethyl acetate, acetonitrile, toluene, xylene, dichloromethane, methanol, tetrahydrofuran, n-butyl acetate, 1,4-dioxane, dimethyl sulfoxide, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone etc.

     To an initial charge of 2,4-diphenyl-6-[8-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-dibenzofuranyl]-1,3,5-triazine [2138490-96-5] (15.31 g, 29.1 mmol), S1e (15.06 g, 27.8 mmol) and K 3 PO 4  (12.17 g, 57.3 mmol) in a flask are added tetrahydrofuran (200 ml) and water (50 ml), and the mixture is inertized with argon for 30 min. Subsequently, Pd(OAc) 2  (124 mg, 0.55 mmol) and XPhos [564483-18-7] (556 mg, 1.11 mmol) are added and the mixture is heated under reflux for 24 h. After cooling, the precipitated solids are filtered off with suction and washed twice with water and twice with ethanol. The crude product is subjected to hot extraction with toluene/heptane (1:1) three times, then recrystallized three times from toluene and finally sublimed under high vacuum. Yield: 14.8 g (18.7 mmol, 67%); purity: &gt;99.9% by HPLC. 
     The following compounds can be prepared analogously: The catalyst system used here (palladium source and ligand) may also be Pd 2 (dba) 3  with SPhos [657408-07-6] or bis(triphenylphosphine)palladium(II) chloride [13965-03-2]. Purification can also be effected using column chromatography, or recrystallization or hot extraction using other standard solvents such as ethanol, butanol, acetone, ethyl acetate, acetonitrile, toluene, xylene, dichloromethane, methanol, tetrahydrofuran, n-butyl acetate, 1,4-dioxane, or recrystallization using high boilers such as dimethyl sulfoxide, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, etc.

     To an initial charge of 2,4-diphenyl-6-[8-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-dibenzofuranyl]-1,3,5-triazine [2138490-96-5] (15.31 g, 29.1 mmol), S1d (14.41 g, 29.5 mmol) and Na 2 CO 3  (6.17 g, 58.2 mmol) in a flask are added toluene (300 ml) and water (100 ml), and the mixture is inertized with argon for 30 min. Subsequently, tetrakis(triphenylphosphine)palladium(0) [14221-01-3] (1.00 g, 0.87 mmol) is added and the mixture is heated under reflux for 36 h. After cooling, the reaction mixture is worked up by extraction with toluene and water, the combined organic phases are dried over Na 2 SO 4 , and the filtrate is concentrated to dryness by rotary evaporation. The residue is suspended in 350 ml of hot EtOH and stirred under reflux for 1 h, and the solids are filtered off with suction after cooling. The crude product is subjected to hot extraction with toluene/heptane (1:1) twice, then recrystallized three times from n-butyl acetate and finally sublimed under high vacuum. Yield: 14.8 g (18.7 mmol, 67%); purity: &gt;99.9% by HPLC. 
     The following compounds can be prepared analogously: The catalyst system used here, rather than tetrakis(triphenylphosphine)palladium(0), may also be Pd 2 (dba) 3  with SPhos [657408-07-6] (palladium source and ligand) or bis(triphenylphosphine)palladium(II) chloride [13965-03-2]. Purification can also be effected using column chromatography, or recrystallization or hot extraction using other standard solvents such as ethanol, butanol, acetone, ethyl acetate, acetonitrile, toluene, xylene, dichloromethane, methanol, tetrahydrofuran, n-butyl acetate, 1,4-dioxane, or recrystallization using high boilers such as dimethyl sulfoxide, N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone, etc.
