Definitions
- the present invention relates to electronic devices such as organic electroluminescent devices (OLEDs), light emitting electrochemical cells (LEECs), organic solar cells (OSCs), organic field effect transistors and organic lasers comprising organo-transition metal complex compounds as light emitters and / or light absorbers. Described are some particularly suitable complex compounds and their use in the opto-electronic field.

- OSCs organic solar cells
- organic field effect transistors organic lasers comprising organo-transition metal complex compounds as light emitters and / or light absorbers. Described are some particularly suitable complex compounds and their use in the opto-electronic field.
- Organo-transition metal complex compounds are important building blocks for opto-electronic devices such as organic solar cells or organic electroluminescent devices. This is especially true for compounds that can act as triplet emitters. In the case of a triplet emission, also called phosphorescence, high internal quantum yields of up to 100% can be achieved, provided that the singlet state, which is excited and energetically above the triplet state, can relax completely into the triplet state and radiationless Competitive processes remain meaningless. Many triplet types that are suitable for opto-electronic applications - -
- emitters have the disadvantage of having a long emission lifetime, e.g. may result in a drop in efficiency in provided with such emitters OLED devices.
- organo-transition metal compounds have been proposed which have a very small energy gap ⁇ between the lowest triplet state and the singlet state lying above them, and which therefore provide efficient back-filling even at room temperature the efficiently occupied ⁇ state into the Si state.
- This reoccupation opens a fast emission channel out of the short-lived Si state, which makes it possible to significantly reduce the total emission lifetime.
- complexes with metal centers were described with a d 8 -Elektronenkonfiguration, ie in particular based on the very expensive metals rhodium, iridium, palladium, platinum and gold.

- the complex compounds described are generally very soluble in organic solvents such as benzene or toluene. This opens up the possibility of printing a fundamentally arbitrary substrate with the complex compounds. Accordingly, there is also a process for producing an electronic device such as the subject-matter of the present invention described above, wherein the described metal complex compound having the at least one anionic ligand of the formula I is printed on a substrate.
- the complexes were generally prepared by stirring the respective tetradentate ligand with an excess of the respective metal halide in tetrahydrofuran. After filtration, it was overlaid with diethyl ether and the crystalline product was isolated.
- the complexes (1) to (5) showed excellent decay behavior and were easy to prepare.
- the tetranuclear copper complex (3) with a PNNP configuration glowed blue both as a solid and in solution as well as in a polymer matrix (polymethyl methacrylate, PMMA).
- FIGS. 1 to 5 show the spatial structures of copper complexes (1) to (5) determined by means of X-ray diffractometry:
- the structure of the dinuclear copper complex (1) is shown in FIG. 1 shown. This complex exhibits an emission at about 515 nm at room temperature in the solid state. - -
- the structure of the trinuclear copper complex (2) is shown in FIG. For clarity, only the ipso carbon atoms of the phenylphosphine radicals are shown.
- This complex exhibits at room temperature in toluene an emission of about 520 nm (with an excitation at about 360 nm).
- FIG. 3 The structure of the tetranuclear copper complex (3) is shown in FIG. This complex shows at room temperature, both in toluene and embedded in a polystyrene matrix, an emission at about 480 nm.
- the structure of the hexanuclear copper complex (4) is shown in FIG. For clarity, the methyl radicals of the isopropyl groups are not shown.
- This complex exhibits emission at about 550 nm at room temperature both as a solid and embedded in a PMMA matrix.
- the structure of the hexanuclear copper complex (5) is shown in FIG. For clarity, the methyl radicals on the cyclohexane rings are not shown.
- This complex shows at room temperature as a solid body emission at about 550 nm and in PMMA at 557 nm.
