Description

[0001] The invention relates to organic molecules, their use in optoelectronic devices such as organic light-emitting diodes (OLEDs) and in other optoelectronic devices, the optoelectronic device and methods for its manufacture. State of the art

[0002] In recent years, OLED (organic light-emitting diode) technology has become established in the field of display technology, and the first commercially available products based on this technology are now on the market. Besides display technology, OLEDs are also suitable for use in area lighting technology. For this reason, intensive research is being conducted into the development of new materials.

[0003] OLEDs are typically implemented in layered structures, which consist predominantly of organic materials. For better understanding, in Fig. Figure 1 shows a simplified structure as an example. The core of such components is the emitter layer, in which emitting molecules are typically embedded in a matrix. In this layer, negative charge carriers (electrons) and positive charge carriers (holes) meet and recombine to form so-called excitons (= excited states). The energy contained in the excitons can be released by the corresponding emitters in the form of light, a process known as 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.

[0004] Since the first reports on OLEDs (Tang et al. Appl. Phys. Lett. 1987, 51, 913), this technology has been continuously developed, particularly in the field of emitter materials. While the first materials, based on purely organic molecules, could only convert a maximum of 25% of excitons into light due to spin statistics, the use of phosphorescent compounds circumvented this fundamental problem, so that, at least theoretically, all excitons can be converted into light. These materials are generally transition metal complexes, in which the metal is chosen from the third period of the transition metals. Predominantly, very expensive precious metals such as iridium, platinum, or gold are used. (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).Besides the costs, the stability of the materials is also sometimes a disadvantage for their use.

[0005] A new generation of OLEDs is based on the exploitation of thermally activated delayed fluorescence (TADF: thermally activated delayed fluorescence, also known as singlet harvesting). For example, Cu(I) complexes can be used, which, due to a small energy gap between the lowest triplet state T1 and the singlet state S1 above it (ΔE(S1-T1)), can thermally reset triplet excitons to a singlet state. Besides the use of transition metal complexes, purely organic molecules (i.e., without a metal ion) can also exploit this effect.

[0013] An aromatic ring system according to this invention contains 6 to 60 carbon atoms in the ring system. A heteroaromatic ring system according to this invention contains 5 to 60 aromatic ring atoms, at least one of which is a heteroatom. The heteroatoms are selected, in particular, from nitrogen, oxygen, and / or sulfur. An aromatic or heteroaromatic ring system according to this invention is understood to be a system that does not necessarily contain only aryl or heteroaryl groups, but in which several aryl or heteroaryl groups may also be linked by a non-aromatic unit (in particular, less than 10% of the different atoms), such as an sp3-hybridized carbon, silicon, or nitrogen atom, an sp2-hybridized carbon, nitrogen, or oxygen atom, or an sp-hybridized carbon atom.For example, systems such as 9,9'-diarylfluorene, triarylamine, diaryl ethers, stilbene, etc., are to be understood as aromatic ring systems within the meaning of this invention, as are systems in which two or more aryl groups are connected, for example, by a linear or cyclic alkyl, alkenyl, or alkynyl group, or by a silyl group.

[0015] AF: Organic chemical unit (residue). It contains at least two different chemical units, AF1 and AF2; AF1: a first chemical unit comprising a conjugated system, in particular at least six conjugated π electrons (e.g., in the form of at least one aromatic system); AF2: a second chemical unit comprising a conjugated system, in particular at least six conjugated π electrons (e.g., in the form of at least one aromatic system); AF2 always has a lower (mathematical) HOMO number value compared to AF1 (and thus also a correspondingly lower LUMO number value than AF1).

[0016] In one embodiment, the molecules according to the invention have the features that - the difference between the energy of the HOMO of the second chemical unit AF2 and the energy of the HOMO of the first chemical unit AF1 > 0.8 eV is (Δ HOMO = HOMO(AF2) - HOMO(AF1) > 0.8 eV); - the difference between 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 between the energy of the LUMO of the first chemical unit AF1 and the energy of the HOMO of the second chemical unit AF2 is > 0.9 eV (Δ Gap = LUMO (AF1) - HOMO(AF2)> 0.9 eV).

[0017] In one embodiment, the chemical units AF1 and AF2 are linked in such a way that electronic communication between them is interrupted. This interruption is characterized by the localization of the frontier orbitals HOMO and LUMO on separate parts of the molecule, thus enabling a charge-transfer transition.

[0018] In one embodiment, the chemical units AF1 and AF2 are connected to each other via a separator such that electronic communication between them is interrupted, characterized by the localization of the frontier orbitals HOMO and LUMO on separate molecular parts. The separator can have any structure, as long as interruption of electronic communication is ensured.

[0019] The energy values ​​HOMO(AF1), HOMO(AF2), LUMO(AF1), and LUMO(AF2) are calculated using density functional theory (DFT), where the attachment positions of the ambifunctional units and separators are saturated with a hydrogen atom according to their chemical valences. The specified limits refer to orbital energies in eV calculated using the BP86 functional (Becke, AD Phys. Rev. A1988, 38, 3098–3100; Perdew, JP Phys. Rev. B1986, 33, 8822–8827).

[0020] Electronic communication between the two chemical units AF1 and AF2 via conjugated bonds with an optional separator is disrupted when the frontier orbitals HOMO and LUMO are localized on separate molecular parts, thus enabling a charge-transfer transition. The localization of the frontier orbitals HOMO or LUMO is visualized using density functional theory (DFT) with the BP86 functional (Becke, AD Phys. Rev. A1988, 38, 3098-3100; Perdew, JP Phys. Rev. B1986, 33, 8822-8827): The one-electron density is calculated from the one-electron wavefunction by squaring and integrated over the space occupied by the molecular part under investigation. This space can be determined from the atomic coordinates and the van der Waals radii of the atoms. The resulting number corresponds to the proportion of the orbital on the molecular part.A majority separation of the frontier orbitals corresponds to an overlap parameter O in the range of 0.1–20%, enabling a charge-transfer transition. The overlap parameter O is between the HOMO wavefunction ϕ. a and the LUMO wave function ϕ b This results from the integral over the entire space of the smaller value of the squared wave function: O=∫ρ dτ with ρ={φa2,if |φa|<|φb|φb2,if |φa|≥|φb|

[0021] Assuming that two different AFs always occur in a molecule, an organic molecule in some embodiments exhibits several identical AFs.

[0022] The part of the organic molecule that represents the non-chemical units AF is also called separator S.

[0023] If the AF is removed, the molecular fragments remain, which are referred to here as separator S.

[0024] In particular, separator S distinguishes the organic molecules from prior art molecules by the separation of AFs (or donors and acceptors) shown here. Known organic emitters generally consist of directly linked chemical units. Separation of the conjugated aromatic systems does not occur in these, especially in connection with the localization of HOMO and LUMO on separate molecular parts. Separators serve to interrupt the electronic communication between the chemical units AF1 and AF2 by linking the units in such a way that the frontier orbitals HOMO and LUMO lie on predominantly separate molecular parts, which is not necessarily the case without the separator. Separators according to this invention do not significantly change the position of the HOMO or LUMO of the AFs shown in Table 1. For the purposes of this invention, a change of no more than ±0.4 eV is considered non-significant.The calculation of such energies is known and works according to the method described above using DFT calculation.

[0025] Spectroscopic selection rules (symmetrical molecules), measurement of the extinction coefficient (UV / VIS spectroscopy), or quantum chemical calculation of the oscillator strength can predict whether a quantum mechanical transition is allowed. The greater the oscillator strength, the more likely a transition is allowed and the faster the associated process (decay time). Decay times of < 50 µs are desirable. With a long decay time of the (organic) emitter, saturation effects occur quickly at high currents, negatively impacting the component lifetime and preventing the achievement of high brightness levels.

[0026] A measure of the decay time is the quantum mechanical overlap integral, which is approximately represented by the overlap parameter O defined above. The smaller the overlap integral, the more separated the frontier orbitals HOMO and LUMO are, and the more likely the charge-transfer transition. However, the probability of TADF emission decreases equally due to decreasing oscillator strengths.

[0027] When the overlap parameter O is set to 1, delayed fluorescence (TADF) due to a charge-transfer transition is no longer present.

[0028] To achieve efficient TADF emission with short decay times, the overlap integral must be adjusted. The desired overlap is achieved by the separator S.

[0029] A measure of the decay time is the ΔE(S1-T1) distance. This is influenced by the overlap of HOMO and LUMO. The magnitude of the quantum mechanical overlap integral, which can be calculated using the DFT method mentioned above, can be specifically controlled by selecting the separator. If complete separation of HOMO and LUMO occurs, this integral has a value of 0. The probability of efficient emission of the organic molecule decreases drastically. At a value of 1, delayed fluorescence (TADF) is replaced by spontaneous emission. The desired overlap is achieved by the separator S according to the invention.

[0030] It is advantageous if the separators S shown have two functional features (see below).
