Description

 Organic molecules, in particular

 for use in optoelectronic devices

The invention relates to purely organic molecules and their use in organic light-emitting diodes (OLEDs) and in other optoelectronic components.

State of the art

 In recent years, the technology based on OLED (organic light-emitting diodes) has established itself in the field of display technology, so that now the first commercial products based on it are available. In addition to screen technology, OLEDs are also suitable for use in flat lighting technology. For this reason, intensive research is being conducted on the development of new materials.

OLEDs are usually realized in layer structures, which consist predominantly of organic materials. For a better understanding, a simplified structure is shown by way of example in FIG. The heart of such components is the emitter layer, in which usually emitting molecules are embedded in a matrix. In this layer, negative charge carriers (electrons) and positive charge carriers (holes) meet, which recombine to form so-called excitons (= excited states). The energy contained in the excitons can be emitted by the corresponding emitters in the form of light, in this case speaking of electroluminescence. An overview of the function of OLEDs can be found, for example, in H. Yersin, Top. Curr. Chem., 2004, 241, 1 and H. Yersin, "Highly Efficient OLEDs with Phosphorescent Materials"; Wiley-VCH, Weinheim, Germany, 2008.

Since the first reports on OLEDs (Tang et al., Appl. Phys. Lett., 1987, 51, 913), this technique has been developed further, especially in the field of emitter materials. While the first materials, which are based on purely organic molecules, could convert up to 25% of the excitons into light due to spin statistics, the use of phosphorescent compounds has circumvented this fundamental problem, so that at least theoretically all excitons can be converted into light. These materials are typically transition metal complex compounds in which the metal is selected from the third period of the transition metals. Here are mainly used very expensive precious metals such as iridium, platinum or gold. (See also H. Yersin, Top. Curr. Chem. 2004, 241, 1, and MA Baldo, DF O'Brien, ME Thompson, SR Forrest, Phys. Rev. B 1999, 60, 14422). In addition to the cost and the stability of the materials is partly detrimental to the use.

 A new generation of OLEDs is based on the utilization of delayed fluorescence (TADF: thermally activated delayed fluorescence or singlet harvesting). In this case, for example, Cu (I) complexes can be used which, due to a small energy gap between the lowest triplet state ΤΊ and the overlying singlet state Si (AE (Si-Ti)), can thermally recombine triplet exitones into a singlet state. In addition to the use of transition metal complexes, purely organic molecules can exploit this effect.

 Some such TADF materials have already been used in first optoelectronic devices. However, the previous solutions have disadvantages and problems: The TADF materials often do not have sufficient long-term stability, sufficient thermal or sufficient chemical stability to water and oxygen in the optoelectronic components. In addition, not all important emission colors are available. Furthermore, some TADF materials are not vaporizable and therefore not suitable for use in commercial optoelectronic devices. Also, some TADF materials do not have adequate energy layers to the other materials used in the optoelectronic device (e.g., HOMO energies of TADF emitters greater than or equal to -5.9 eV). It is not possible to achieve sufficiently high efficiencies of the optoelectronic components with high current densities or high luminances with all TADF materials. Furthermore, the syntheses of some TADF materials are expensive.

By definition, AF2 always has a lower HOMO value (compared to AF1) and thus a lower LUMO value than AF2 (| E _HO MO (AF2) | <| E _HO MO (AF1) | and | E _LUM o (AF2) | <| E _LUM o (AF1) |);

wherein the chemical units AF2 correspond to the formula 1a and the chemical units AF1 correspond to the formula 1b.

In one embodiment, the organic molecules are characterized in that

the difference of the energy of the HOMO of the second chemical entity AF2 and the energy of the HOMO of the first chemical entity AF1 is> 0.8 eV (ΔHOMO = HOMO (AF2) -HOMO (AF1)> 0.8 eV);

 the difference of the energy of the LUMO of the second chemical unit AF2 and the energy of the LUMO of the first chemical unit AF1 is> 0.8 eV (Δ LUMO = LUMO (AF2) -LUMO (AF1)> 0.8 eV); and or

 the difference of the energy of the LUMO of the first chemical entity AF1 and the energy of the HOMO of the second chemical entity AF2> 0.9 eV is (ΔGap = LUMO (AF1) -HOMO (AF2)> 0.9 eV).

In another embodiment, organic molecules of the invention have one or more units AF1 selected from the structures 40, 61, 62, 68, 86, 113, 123, 150, 151, 152, 153, 154, 205, 209 , 244, 286, 288, 297, 303, 311, 313, 332, 358, 370, 371 of Table 2; the other unit (s) AF2 being selected from the structures of Table 1.

In particular, the use of structures according to the formulas 1a, 2a or 2e or from Table 1 and the use of structures according to the formulas 1b or 2f to 2z or from Table 2 functionally differentiates the organic molecules of the invention from molecules of the prior art. Due to the attached attachment patterns, the two pi systems of AF1 and AF2 are not in conjugation, but are nevertheless fixed in close spatial proximity.

By means of spectroscopic selection rules (symmetric molecules) or by measuring the extinction coefficient (UV / VIS spectroscopy) or by quantum chemical calculation of the oscillator strength, it can be predicted whether a quantum mechanical transition is allowed. The larger the oscillator strength, the sooner a transition is allowed and the faster the associated process (cooldown). The aim is to have a decay time of <300 ps, in particular <100 ps or <50 ps. With a long decay time of the (organic) emitter, saturation effects quickly occur at high current intensities, which adversely affects the component lifetime and prevents the achievement of high brightness levels.

 A measure of the decay time is the AE (Si-T-i) distance. This is influenced by the overlap of HOMO and LUMO. The size of the quantum mechanical overlap integral, which can be calculated using the above-mentioned DFT method, can be controlled in a targeted manner. If it comes to the complete separation of HOMO and LUMO this has a value of 0. The probability of an efficient emission of the organic molecule decreases drastically. At a value of 1 there is no longer delayed fluorescence (TADF) but spontaneous emission.

In one embodiment, further radicals R are added to the chemically substitutable positions of the organic molecules thus obtained in order to increase the solubility of the emitters and / or to allow the polymerizability without significantly changing the electronic properties of the molecule, so that even when using R an emitter is present, wherein

each R independently of each occurrence is selected from the group consisting of H, deuterium, phenyl, naphthyl, F, Cl, Br, I, N (R ² ) ₂ , -CN, -NC, -SCN, -CF ₃ , - N0 _2, -OH, C (= 0) OH, C (= 0) OR ^3, C (= 0) N (R ³⁾ _2, C (= 0) SR ^3, C (= S) SR ^3, Si (R ⁴ ) ₃ , B (OR ⁵ ) ₂ , B (N (R ⁶ ) ₂ ) ₂ , C (= O) R ³ , P (= 0) (R ⁷ ) ₂ , As (= 0) ( R ⁷ ) ₂ , P (= S) (R ⁷ ) ₂ , As (= S) (R ⁷ ) ₂ , S (= O) R ³ , S = NR ³ , S (= O) NR ³ , S ( = 0) ₂ NR ³ , S (= O) ₂ R ³ , 0-S (= O) ₂ R ³ , SF ₅ , a linear alkyl, alkoxy or thioalkoxy group having 1 to 40 carbon atoms or a linear alkenyl or alkynyl group having 2 to 40 carbon atoms or a branched or cyclic alkyl, alkenyl, alkynyl, alkoxy or thioalkoxy group having 3 to 40 carbon atoms, each of which may be substituted by one or more R ⁹ radicals, wherein one or more adjacent CH ₂ groups by - R ⁹ C = CR ⁹ -, -CEC-, or an adjacent CH ₂ group by -Si (R ⁴ ) ₂ -, -Ge (R ⁴ ) ₂ -, - Sn (R ⁴ ) ₂ , - C (= O) -, -C (= S) -, -C (= Se) -, -C = N-, -C (= O) O-, -C (= O) N (R ³ ) - , -P (= 0) (R ⁷ ) -, -As (= 0) (R ⁷ ) -, - P (= S) (R ⁷ ) -, -As (= S) (R ⁷ ) -, - S (= O) -, -S (= O) ₂ -, -NR ² -, -O-, or -S- may be replaced and wherein one or more H atoms are represented by deuterium, F, Cl, Br, I , CN, CF ₃ or N0 ₂ may be replaced, or an aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, each of which may be substituted by one or more radicals R ² , or an aryloxy or heteroaryloxy group having 5 to 60 aromatic ring atoms which may be substituted by one or more radicals R ⁹ , or a diarylamino group, diheteroarylamino group or arylheteroarylamino group having 10 to 40 aromatic ring atoms which may be substituted by one or more radicals R ⁹ , or a combination of these systems; two or more of these substituents R may also together form a monocyclic aliphatic ring system with a total of five or six ring members. For R ² to R ⁹ , the definitions given in formula 1 apply.

Polymerizable radicals are those radicals which carry polymerizable functional units which can be homopolymerized with themselves or copolymerized with other monomers. Thus, the molecules of the invention can be obtained as a polymer having the following repeating units of the formulas 4 and 5, which can be used as polymers in the light-emitting layer of the optoelectronic component.
