Definitions
- An electroluminescent (EL) arrangement is characterized in that it emits light when an electrical voltage is applied under current flow.
- LEDs light emitting diodes
- the emission of light occurs because positive charges ("holes”, holes) and negative charges (“electrons”, electrons) recombine while emitting light.
- inorganic semiconductors such as gallium arsenide are used today.
- Point-like display elements can be produced on the basis of such substances. Large-scale arrangements are not possible.
- electroluminescent arrangements based on evaporated low-molecular organic compounds are known (US Pat. Nos. 4,539,507, 4,769,262, 5,077,142, EP 0 406 762, EP 0 278 758, EP) -A 0 278 757).
- Polymers such as poly (p-phenylene) and poly (p-phenylene vinylene (PPV)) are also described as electroluminescent polymers: G. Leising et al, Adv. Mater. 4 (1992) No. 1; Friend et al., J. Chem. Soc, Chem. Commun. 32 (1992); Saito et al, Polymer, 1990, vol. 31, 1137; Friend et al, Physical Review B, Vol. 42, No. 18, 11670 or WO-A 90/13148.
- Further examples of PPV in electroluminescent displays are described in EP-A 0 443 861, WO-A 92/03490 and 92/03491.
- EP-A 0 294 061 presents an optical modulator based on polyacetylene.
- PPV derivatives proposed (WO-A 92/16023).
- Polymer blends of different compositions are also known: M. Stolka et al., Pure & Appt. Chem., Vol. 67, No. 1, pp 175-182, 1995; H. Bässler et al., Adv. Mater. 1995, 7, No. 6, 551; K. Nagai et al., Appl. Phys. Lett. 67 (16), 1995, 2281; EP-A 0 532 798.
- the organic EL devices typically contain one or more layers of organic charge transport compounds.
- the basic structure in the order of the layers is as follows:
- Layers 3 to 7 represent the electroluminescent element.
- an EL arrangement consists of two electrodes, between which there is an organic layer that fulfills all functions - including the emission of light.
- Such systems are described, for example, in application WO-A 90/13148 based on poly (p-phenylene vinylene).
- Multi-layer systems can be built up by vapor deposition processes, in which the layers are applied successively from the gas phase, or by casting processes. Casting processes are preferred due to the higher process speeds. However, the dissolving process of a layer that has already been applied can be difficult in certain cases when layering over with the next layer.
- the object of the present invention is to provide electroluminescent arrangements with high luminance, novel metal complexes with improved solubility in common solvents being used as emitters and / or electron conductors. These new types of metal complexes should also be able to be applied by vapor deposition from the gas phase.
- zone is synonymous with layer.
- the present invention therefore relates to an electroluminescent arrangement composed of a substrate, an anode, an electroluminescent element and a cathode, at least one of the two electrodes being transparent in the visible spectral range and the electroluminescent element being one or more zones from the group of the hole-injecting zone , hole-transporting zone, electroluminescent zone, electron-transporting zone and electron-injecting zone in the order mentioned, each of the zones present also being able to take on tasks of the other zones mentioned, characterized in that the electroluminescent element contains a thiophene carboxylate metal complex.
