Definitions
- organic electroluminescent materials and devices have also been known for about 30 years (see, for example, US-A-3, 172,862). Until recently, however, such devices were severely limited in their practical applicability.
- EP 423 283 and EP 443 861 describe electroluminescent devices which contain a film of a conjugated polymer as the light-emitting layer (semiconductor layer). Such devices offer many
- a typical device according to EP 423 283 consists of a light-emitting device
- a first contact layer is in Contact with a first surface, a second contact layer with a further surface of the semiconductor layer.
- the polymer film of the semiconductor layer has a sufficiently low concentration of extrinsic charge carriers, so that charge carriers are introduced into the semiconductor layer when an electric field is applied between the two contact layers, one of which
- Conjugated polymer is a polymer that has a delocalized electron system along the main chain.
- the delocalized electron system gives the polymer semiconductor properties and gives it the ability to transport positive and / or negative charge carriers with high mobility.
- EP 423 283 and EP 443 861 describe poly- (p-phenylene-vinylene) as the polymeric material for the light-emitting layer, which is used for
- Patent application WO98 / 27136 describes aryl-substituted poly (p-arylenevinylenes) which are also suitable for producing green electroluminescence.
- a further improvement of the polymers published there can be seen from WO99 / 24526.
- a defect in such polymers is also disclosed here: depending on the polymer, different proportions of triple and single bonds (TBB defect) occur in the main chain. The proportion of this defect appears to be reciprocal in relation to the achievable lifespan: a high proportion of defects lowers the operative lifespan, a low proportion significantly increases it.
- the defect rate can be influenced by the substitution pattern used, and that this rate starting from aryl-substituted monomers (according to WO98 / 27136) can be significantly reduced by the insertion of CN, F, Cl, an amino, alkyl or (thio) alkoxy group.
- Solubility or insolubility in the sense of this application should be defined, as is also specified in W099 / 21936 (page 3, lines 2 to 7): Soluble polymers therefore means that they have a concentration range of at least 0.5% in a common organic solvent (aromatic , as well as non-aromatic solvents, which can contain halogen or can also be halogen-free, such as Toluene, anisole, chlorobenzene, methylene chloride, chloroform, xylene, dioxane, THF, cyclohexanone and the like. ⁇ .) form a clear, ungelled solution at room temperature or at least at a temperature below 60 ° C, preferably below 50 ° C, particularly preferably below 40 ° C. This property is necessary in order to guarantee technical processing into thin films.

- polymers are insoluble which only give a clear solution at significantly lower concentrations, or which already gel above approx. 60 ° C.
- the polymers of the invention show such a solubility, in contrast, the polymers disclosed in US 5,558,904 do not have such a solubility, so that they are not identical.
- the polymers of the invention represent a significant improvement over this prior art.
- Solubility of polymers made from such monomers is not achieved by suitable substitution or copolymerization but by lowering the molecular weight. However, this measure is detrimental to the goal of a long operating life in an electroluminescent device.
- WO99 / 21936 discloses soluble polymers (page 3), it is not known how these soluble polymers can be achieved with the disclosed terphenyl structures should be. This is particularly unclear if these structures are present in proportions of more than 25%, as is preferred in WO99 / 21936 (page 2, lines 6 to 12 in connection with the information in table 2, page 20). If the explicitly named monomer 4,4 "-bis (3,7-dimethyloctyloxy) -2 ', 5'-bis (chloromethyl) -p-terphenyl is used, for example, in a ratio of 30 mol% as

- copolymers which have 1, 2 or 3 different repeating units of the formula (I).
- Copolymers in the sense of the invention include statistical, alternating, regular and block-like structures. Likewise preferred are polymers containing repeating units of the formula (I) in which the symbols and indices have the following meanings:
- Aryl 1 , aryl 2 is the same or different phenyl, 1- or 2-naphthyl, 1-, 2- or 9-
- aryl substituents aryl 1 , aryl 2 in formula (I) have the following meanings are particularly preferred: phenyl, 1-naphthyl, 2-naphthyl or 9-

- Repeating unit according to formula (I) are in each case identical or different from one another. Differences can already exist due to a different substitution pattern. To increase solubility, this can be a preferred embodiment of the invention.
- the polymers according to the invention can be obtained, for example, from starting materials of the formula (IV) in which the symbols and indices have the meaning explained under formula (I) and shark, shark 'represents Cl, Br or I by dehydrohalogenation polymerization; this is usually done by reacting one or more monomers in a suitable solvent with a suitable base.
- polymers which contain repeating units of the formula (I) can now be synthesized by the above-mentioned polymerization variant - with the addition of further comonomers.
- Such comonomers are, for example, the compounds listed below.
- electroluminescent materials are materials which can be used as an active layer in an electroluminescent device.
- Active layer means that the layer is capable of emitting light when an electric field is applied (light-emitting layer) and / or that it improves the injection and / or the transport of the positive and / or negative charges
