In one embodiment, the organic molecules according to the invention have an excited state lifetime of not more than 5.0 µs, of not more than 2.5 µs, in particular of not more than 2.0 µs, more preferably of not more than 1.0 µs or not more than 0.7 µs in a film of poly(methyl methacrylate) (PMMA) with 1 % to 5 %, in particular with 2 % by weight of organic molecule at room temperature. In a further embodiment of the invention, the organic molecules according to the invention have an emission peak in the visible or nearest ultraviolet range, i.e., in the range of a wavelength of from 380 to 800 nm, with 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) with 1 % to 5 %, in particular with 2 % by weight of organic molecule at room temperature. Orbital and excited state energies can be determined either by means of experimental methods. The energy of the highest occupied molecular orbital E ^HOMO is determined by methods known to the person skilled in the art from cyclic voltammetry measurements with an accuracy of 0.1 eV. The energy of the lowest unoccupied molecular orbital E ^LUMO is calculated as E ^HOMO + E ^gap , wherein E ^gap is determined as follows: For host compounds, the onset of the emission spectrum of a film with 10 % by weight of host in poly(methyl methacrylate) (PMMA) is used as E ^gap , unless stated otherwise. For emitter molecules, E ^gap is determined as the energy at which the excitation and emission spectra of a film with 1 % to 5 %, in particular with 2 % by weight of emitter in PMMA cross. For the organic molecules according to the invention, E ^gap is determined as the energy at which the excitation and emission spectra of a film with 1 % to 5 %, in particular with 2 % by weight of emitter in PMMA cross. The energy of the first excited triplet state T1 is determined from the onset of the emission spectrum at low temperature, typically at 77 K. For host compounds, where the first excited singlet state and the lowest triplet state are energetically separated by > 0.4 eV, the phosphorescence is usually visible in a steady-state spectrum in 2-Me-THF. The triplet energy can thus be determined as 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, if not otherwise stated, measured in a film of PMMA with 1 % to 5 %, in particular with 2 % by weight of emitter and in case of the organic molecules according to the invention with 1 % to 5 %, in particular with 2 % by weight of the organic molecules according to the invention. Both for host and emitter compounds, the energy of the first excited singlet state S1 is determined from the onset of the emission spectrum, if not otherwise stated, measured in a film of PMMA with 10 % by weight of host or emitter compound and in case of the organic molecules according to the invention with 1 % to 5 %, in particular with 2 % by weight of the organic molecules according to the invention. The onset of an emission spectrum is determined by computing the intersection of the tangent to the emission spectrum with the x-axis. The tangent to the emission spectrum is set at the high-energy side of the emission band and at the point at half maximum of the maximum intensity of the emission spectrum.

In a further aspect, the invention relates to an optoelectronic device comprising an organic molecule or a composition of the type described here, more particularly in the form of a device selected from the group consisting of organic light-emitting diode (OLED), light-emitting electrochemical cell, OLED sensor, more particularly gas and vapour sensors not hermetically externally shielded, organic diode, organic solar cell, organic transistor, organic field-effect transistor, organic laser and down-conversion element. 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. In one embodiment of the optoelectronic device of the invention, the organic molecule according to the invention E is used as emission material in a light-emitting layer EML. In one embodiment of the optoelectronic device of the invention, the light-emitting layer EML consists of the composition according to the invention described here. When the optoelectronic device is an OLED, it may, for example, have 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, wherein the OLED comprises each layer selected from the group of HIL, HTL, EBL, HBL, ETL, and EIL only optionally, different layers may be merged and the OLED may comprise more than one layer of each layer type defined above. Furthermore, the optoelectronic device may, in one embodiment, comprise one or more protective layers protecting the device from damaging exposure to harmful species in the environment including, for example, moisture, vapor and/or gases. In one embodiment of the invention, the optoelectronic device is an OLED, with 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 wherein the OLED comprises each layer selected from the group of HIL, HTL, EBL, HBL, ETL, and EIL only optionally, different layers may be merged and the OLED may comprise more than one layer of each layer types defined above. In one embodiment of the invention, the optoelectronic device is an OLED, which may have a stacked architecture. In this architecture, contrary to the typical arrangement in which the OLEDs are placed side by side, the individual units are stacked on top of each other. Blended light may be generated with OLEDs exhibiting a stacked architecture, in particular white light may be generated by stacking blue, green and red OLEDs. Furthermore, the OLED exhibiting a stacked architecture may comprise a charge generation layer (CGL), which is typically located between two OLED subunits and typically consists of a n-doped and p-doped layer with the n-doped layer of one CGL being typically located closer to the anode layer. In one embodiment of the invention, the optoelectronic device is an OLED, which comprises two or more emission layers between anode and cathode. In particular, this 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 may comprise further layers such as charge generation layers, blocking or transporting layers between the individual emission layers. In a further embodiment, the emission layers are adjacently stacked. In a further embodiment, the tandem OLED comprises a charge generation layer between each two emission layers. In addition, adjacent emission layers or emission layers separated by a charge generation layer may be merged. The substrate may be formed by any material or composition of materials. Most frequently, glass slides are used as substrates. Alternatively, thin metal layers (e.g., copper, gold, silver or aluminum films) or plastic films or slides may be used. This may allow for a higher degree of flexibility. The anode layer A is mostly composed of materials allowing to obtain an (essentially) transparent film. As at least one of both electrodes should be (essentially) transparent in order to allow light emission from the OLED, either the anode layer A or the cathode layer C is transparent. Preferably, the anode layer A comprises a large content or even consists of transparent conductive oxides (TCOs). Such anode layer A may, for example, comprise 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 GaAs, doped polyaniline, doped polypyrrol and/or doped polythiophene. The anode layer A (essentially) may consist of indium tin oxide (ITO) (e.g., (InO ₃ ) _0.9 (SnO ₂ ) _0.1 ). The roughness of the anode layer A caused by the transparent conductive oxides (TCOs) may be compensated by using a hole injection layer (HIL). Further, the HIL may facilitate the injection of quasi charge carriers (i.e., holes) in that the transport of the quasi charge carriers from the TCO to the hole transport layer (HTL) is facilitated. The hole injection layer (HIL) may comprise poly-3,4-ethylendioxy thiophene (PEDOT), polystyrene sulfonate (PSS), MoO ₂ , V ₂ O ₅ , CuPC or CuI, in particular a mixture of PEDOT and PSS. The hole injection layer (HIL) may also prevent the diffusion of metals from the anode layer A into the hole transport layer (HTL). The HIL may, for example, comprise PEDOT:PSS (poly-3,4-ethylendioxy thiophene: polystyrene sulfonate), PEDOT (poly-3,4-ethylendioxy thiophene), 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'-nis-(1-naphthalenyl)-N,N'-bis-phenyl-(1,1'-biphenyl)- 4,4'-diamine), NPNPB (N,N'-diphenyl-N,N'-di-[4-(N,N-diphenyl-amino)phenyl]benzidi ne), MeO-TPD (N,N,N′,N′-tetrakis(4-methoxyphenyl)benzidine), HAT-CN (1,4,5,8,9,11- hexaazatriphenylen-hexacarbonitrile) and/or Spiro-NPD (N,N′-diphenyl-N,N′-bis-(1-naphthyl)- 9,9′-spirobifluorene-2,7-diamine). Adjacent to the anode layer A or hole injection layer (HIL), a hole transport layer (HTL) is typically located. Herein, any hole transport compound may be used. For example, electron- rich heteroaromatic compounds such as triarylamines and/or carbazoles may be used as hole transport compound. The HTL may decrease the energy barrier between the anode layer A and the light-emitting layer EML. The hole transport layer (HTL) may also be an electron blocking layer (EBL). Preferably, hole transport compounds bear comparably high energy levels of their triplet states T1. For example, the hole transport layer (HTL) may comprise a star-shaped heterocycle such as tris(4-carbazoyl-9-ylphenyl)amine (TCTA), poly-TPD (poly(4- butylphenyl-diphenyl-amine)), [alpha]-NPD (poly(4-butylphenyl-diphenyl-amine)), TAPC (4,4′- cyclohexyliden-bis[N,N-bis(4-methylphenyl)benzenamine]), 2-TNATA (4,4′,4′′-tris[2- naphthyl(phenyl)amino]triphenylamine), Spiro-TAD, DNTPD, NPB, NPNPB, MeO-TPD, HAT- CN and/or TrisPcz (9,9'-diphenyl-6-(9-phenyl-9H-carbazol-3-yl)-9H,9'H-3,3'-bic arbazole). In addition, the HTL may comprise a p-doped layer, which may be composed of an inorganic or organic dopant in an organic hole-transporting matrix. Transition metal oxides such as vanadium oxide, molybdenum oxide or tungsten oxide may, for example, be used as inorganic dopant. Tetrafluorotetracyanoquinodimethane (F4-TCNQ), copper-pentafluorobenzoate (Cu(I)pFBz) or transition metal complexes may, for example, be used as organic dopant. The EBL may, 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). Adjacent to the hole transport layer (HTL), the light-emitting layer EML is typically located. The light-emitting layer EML comprises at least one light emitting molecule.

Production and characterization of optoelectronic devices Optoelectronic devices, such as OLED devices comprising organic molecules according to the invention can be produced via vacuum-deposition methods. If a layer contains more than one compound, the weight-percentage of one or more compounds is given in %. The total weight- percentage values amount to 100 %, thus if a value is not given, the fraction of this compound equals to the difference between the given values and 100 %. The not fully optimized OLEDs are characterized using standard methods and measuring electroluminescence spectra, the external quantum efficiency (in %) in dependency on the intensity, calculated using the light detected by the photodiode, and the current. The OLED device lifetime is extracted from the change of the luminance during operation at constant current density. The LT50 value corresponds to the time, where the measured luminance decreased to 50 % of the initial luminance, analogously LT80 corresponds to the time point, at which the measured luminance decreased to 80 % of the initial luminance, LT 95 to the time point, at which the measured luminance decreased to 95 % of the initial luminance etc. Accelerated lifetime measurements are performed (e.g. applying increased current densities). For example, LT80 values at 500 cd/m ² are determined using the following equation: wherein L0 denotes the initial luminance at the applied current density. The values correspond to the average of several pixels (typically two to eight), the standard deviation between these pixels is given.
