Definitions
- the conjugated polymers according to the prior art sometimes already show good properties when used in PLEDs. Despite the progress made, however, they do not yet meet the requirements placed on them for unproblematic processing and for high-quality applications. Thus, the stability of many polymers according to the prior art against oxygen and / or other air constituents is by no means satisfactory. H. the polymers show significantly poorer properties in PLEDs after contact with air. As a result, the efficiency and lifespan of the polymers decrease drastically. This necessitates the processing of the polymers and the production of the PLEDs under inert conditions, which represents a considerable additional outlay and thus a technological disadvantage.
- the PLED results obtained with these polymers show that these polymers are still not suitable for electroluminescence: the threshold voltages are higher than 8 V, depending on the polymer and device configuration even up to 20 V, and the external quantum efficiencies are in the range from 0.05 to 0.6%, sometimes even much lower. Both the voltages and the quantum efficiencies are thus well behind the prior art, and it is obvious that the higher PL quantum efficiency does not contribute to satisfactory EL efficiencies. These polymers are therefore unsuitable for commercial use in PLEDs.
- Copolymers of this unit with phenylene units are also known. This results in alternating thienylene-phenylene polymers (e.g. J.M. Xu et al., Macromolecules 2001, 34, 4314). Results of these polymers in electroluminescence are not shown; however, it can be inferred from the description that these polymers are not suitable for electroluminescence. Some derivatives are described as showing strong interaction of the polymer chains, which results in a shift in the fluorescence wavelength. Such emission bands often show a very low efficiency. In addition, these polymers could only be produced with a low molecular weight, which for industrial use, e.g. B. the processing by printing techniques is unusable.
- the polymers are only very poorly soluble in solvents such as toluene or xylene, which are usually used for processing the polymers from solution.
- solvents such as toluene or xylene, which are usually used for processing the polymers from solution.
- the production of PLEDs with these polymers is therefore associated with considerable difficulties, or will only be possible in poor quality.
- Copolymers of unsubstituted dithienylphenylene or dithienylanthrylene units with spirobifluorenes and other comonomers have been shown as examples in WO 03/020790. There are no particular advantages of these units. However, polymers containing these units have problems in synthesis and processing due to the poor solubility of the oligomers and polymers. For example, synthesis is often not possible in homogeneous solution, processing is more difficult, as are the preparation of solutions for these polymers, and when used in PLEDs, no homogeneous films of the polymers are obtained.
- the invention relates to polymers containing at least 5 mol%, preferably at least 10 mol%, particularly preferably at least 40 mol% of units of the formula
- X is the same or different on each occurrence CR 2 , N (R 1 ), -CR 2 -CR 2 - or -N (R 1 ) -CR 2 -;
- Z is the same or different at each occurrence CR or N;
- radicals R can and which can also be substituted by one or more non-aromatic radicals R, it also being possible for two or more of the radicals R to form an aromatic or aliphatic, mono- or polycyclic ring system with one another, or fluorine, chlorine, CN, N (R 1 ) 2 , Si (R 1 ) 3 or B (R 1 ) 2 ;
- A is the same or different at each occurrence S, O or N (R 1 );
- Z is the same or different at each occurrence CR or N, with the proviso that the central unit (II) describes no quinoxaline, no benzothiadiazole and no unsubstituted anthracene and with the further proviso that at least one radical R is not hydrogen; m is the same or different at each occurrence 1, 2 or 3; the other symbols are as described under formula (1); the dashed bond in formula (1) and formula (2) as in all other formulas means the linkage in the polymer; it should not represent a methyl group here.
- radicals R can form a ring system with one another. This also applies in particular to the radicals R at position X, so that, for example, spiro systems, in particular spirobifluorene, are expressly included. This also enables more extensive bridged systems, such as, for example, ice or trans-indofluorene or related structures.
- the polymers according to the invention can be conjugated, partially conjugated or non-conjugated.
- the polymers are conjugated or partially conjugated, in a particularly preferred embodiment the polymers are conjugated.
- conjugated polymers are polymers which contain mainly sp 2 -hybridized (or also sp-hybridized) carbon atoms in the main chain, which can also be replaced by corresponding heteroatoms. In the simplest case, this means alternating double and single bonds in the main chain. Mainly means that of course (involuntary) defects that occur Conjugation interruptions lead, do not invalidate the term "conjugated polymer".
- this application text also refers to conjugate if, for example, arylamine units and / or certain heterocycles (ie conjugation via N, O or S atoms) and / or organometallic complexes (ie conjugation via the metal atom) are present in the main chain .
- units such as simple (thio) ether bridges, alkylene bridges, ester, amide or imide linkages would be clearly defined as non-conjugated segments.
- partially conjugated polymers are understood as meaning polymers in which longer conjugated sections in the main chain are interrupted by non-conjugated sections, or polymers which contain longer conjugated units in the side chains of a polymer which is not conjugated in the main chain.
- the polymers according to the invention can also contain further structural elements. These are u. a. such as those in the
- Patent applications WO 02/077060 and DE 10337346.2 have already been disclosed. The others
- Structural units can, for example, come from the classes described below:
- Group 1 units which significantly increase the hole injection and / or transport properties of the polymers
- Group 2 units which significantly increase the electron injection and / or transport properties of the polymers
- Group 3 units which have combinations of individual units of group 1 and group 2
- Group 4 units which influence the morphology or, if appropriate, also the emission color of the polymers.
- HOMO highest lying occupied molecular orbital
- LUMO lowest unoccupied molecular orbital
- the polymers according to the invention contain units from group 3 in which units which increase the hole transport properties and which increase the electron transport properties, ie units from group 1 and group 2, are bonded directly to one another. Such units often lead to color shifts in yellow or red in the polymer.
- Aromatic, carbocyclic structures which have 6 to 40 C atoms, or stilbene or bisstyrylarylene derivatives, which can each be substituted or unsubstituted by a C 1 to C 40 organic radical, are preferred.
- metal complexes that can emit light from the singlet or triplet state or that can also perform other functions.
- the polymers according to the invention generally have 10 to 10,000, preferably 20 to 5000, particularly preferably 50 to 2000 repeating units.
- an average of at least 2 non-aromatic C atoms are present in the substituents per repeating unit. At least 4, particularly preferably at least 8, non-aromatic C atoms are preferred. Some of these C atoms can also be replaced by O or S. However, this can mean that a certain proportion of repetition units, according to formulas (1) and (2) as well as other structure types, do not have any more carries non-aromatic substituents. For good solubility of the polymer, however, it is necessary for the units of the formula (2) to have at least one aromatic or preferably non-aromatic substituent.
- any long-chain substituents with more than 12 C atoms in a linear chain, preferably none with more than 8 C atoms, particularly preferably none with more than 6 C atoms ,
- non-aromatic C atoms are contained in corresponding straight-chain, branched or cyclic alkyl or alkoxy chains.
- X CR 2 or CR 2 -CR 2 also preferably applies to the group ,
- These structural units are very particularly preferably selected from the groups of the fluorenes according to formula (3), the 9,9'-spirobifluorenes according to formula (4) which are substituted or unsubstituted with an organic radical to C 40 or the dihydrophenanthrenes according to formula (5):
- Formula (3) Formula (4): Formula (5): fluorene spiro-9,9'-bifluorene 9,10-dihydrophenanthrene
- Preferred structures are ice or trans-indofluorenes according to formulas (6) and (7):
- Formula (6) Formula (7): trans-indofluorene, cis-indofluorene
- Z is the same or different CR on each occurrence, the above restrictions still apply; A is the same or different at each occurrence O or S; m is the same or different at each occurrence 1 or 2; the other symbols are defined as above under formula (2).
- Z is the same or different CR on each occurrence, the above restrictions still apply and at least two radicals R not equal to hydrogen; A is S on every occurrence; R is as defined above under formula (1); R 1 is as defined above; m is 1 for each occurrence.
- copolymers according to the invention can have statistical, alternating or block-like structures. How copolymers with block-like structures can be obtained is described in detail, for example, in the unpublished application DE 10337077.3. Properties such as solubility, solid phase morphology, color, charge injection and transport properties, optoelectronic characteristics, etc. can be set by using different structural elements.
- Polymers according to the invention are preferred which, in addition to structural units according to formulas (1) and (2), also contain at least one structural unit from groups (1) to (4). It is particularly preferred if at least one of these structural units has charge transport properties, that is to say the polymer contains structural units from group (1) and / or (2).
- the proportion of these structural elements is preferably at least 1 mol%, particularly preferably at least 5 mol%, very particularly preferably at least 10 mol%.
- the maximum proportion of these structural elements is preferably at most 80 mol%, particularly preferably at most 40 mol%.
- the polymers according to the invention are prepared by polymerizing several monomers, of which at least one repeats units of the formula (1) and one repeats unit of the formula (2). A few polymerization reactions have all proven particularly useful, all of which lead to C-C linkages:
- polymer according to the invention may also be preferred not to use the polymer according to the invention as a pure substance, but as a mixture (blend) together with other polymeric, oligomeric, dendritic or low-molecular substances. These can, for example, improve hole or electron transport or influence the charge balance. Such blends are therefore also part of the present invention.
- the invention further relates to solutions and formulations of one or more polymers or blends according to the invention in one or more solvents.
- polymer solutions can be prepared is described, for example, in WO 02/072714, WO 03/019694 and the literature cited therein. These solutions can be used to produce thin polymer layers, for example by surface coating processes (for example spin coating) or by printing processes (for example inkjet printing).
- the polymers according to the invention can be used in PLEDs. How PLEDs can be produced is described in detail as a general method in WO 04/037887, which must be adapted accordingly for the individual case. As already described above, the polymers according to the invention are particularly suitable as electroluminescent materials in PLEDs or displays produced in this way.
- electroluminescent materials are materials which can be used as an active layer in a PLED.
- 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 (charge injection or charge transport layer).
- the invention therefore also relates to the use of a polymer or blend according to the invention in a PLED, in particular as an electroluminescent material.
- the polymer according to the invention or the blend preferably serves as the emitting material.
- the invention also relates to a PLED with one or more active layers, at least one of these layers containing one or more polymers or blends according to the invention.
- the active layer can be, for example, a light-emitting layer and / or a charge transport layer and / or a charge injection layer.
- the polymers according to the invention have the following advantages:
- the polymers according to the invention have a significantly higher air stability than polymers according to the prior art. This applies in particular to green-emitting copolymers. This is of enormous importance since the processing of the polymers and the manufacturing process of the PLEDs can be significantly simplified. While previously the polymer films had to be produced in an inert atmosphere for optimal electroluminescence results, which means a considerable technological outlay, the polymer films with polymers according to the invention can be produced in air without the electroluminescence suffering as a result.
- the polymers according to the invention show significantly better properties than polymers which contain unsubstituted units of the formula (2). They have better solubility in a wider range of solvents and are not prone to gel formation. This makes the polymers easier to process and forms more homogeneous films in the PLED. Processing by printing techniques, e.g. B. Inkjet printing is made possible. It also enables a higher proportion of these units to be polymerized into the polymer than is possible with unsubstituted units.
- a combination of units of the formulas (1) and (2) and possibly further units leads to polymers which emit green (or, depending on the comonomer, also red or white) light with very good color coordinates. Although this is not an immediate advantage, since other polymers also have good color coordinates, it is a crucial prerequisite for the use of these polymers. In particular, polymers according to the invention have better color coordinates in the green than comparable polymers which contain unsubstituted units of the formula (2).

- HPLC had a purity of 99.7%. The yield was 50 g (92%).
- the polymers were synthesized by SUZUKI coupling according to WO 03/048225.
- the composition of the synthesized polymers P1 to P4 (Examples 8 to 11) is summarized in Table 1.
- Comparative polymers (Examples 12 to 14; hereinafter referred to as V) were also synthesized, which instead of units according to formula (2) contain monomer M5 or monomer M6 as green-emitting units according to the prior art.
- Table 1 Properties of polymers according to the invention and their comparison with polymers according to the prior art; all polymers were made via a Suzuki polymerization. * GPC measurements: THF; 1 mL / min, Plgel 10 ⁇ m Mixed-B 2 x 300 x 7.5 mm 2 , 35 ° C, Rl detection was calibrated against polystyrene.
- Example 16 Comparison of the viscosity of the polymer solutions The viscosity of some polymer solutions with substituted and unsubstituted dithienylarylene units was investigated. The results are shown in Table 2.
- the polymers according to the invention have a viscosity which is many times lower than polymers according to the prior art which contain unsubstituted dithienylia / Ien units. This becomes all the more evident since the polymers P1 and P3 examined here have a (in some cases significantly) higher molecular weight than the comparative polymer V3 and the viscosity increases with the molecular weight.
- the concentration of the comparative polymer was lower than that of the polymers of the invention, and the viscosity of a polymer solution increases with increasing concentration. If one also takes these aspects into account, it can be concluded that the effect is even more pronounced if polymers of the same molecular weight are compared in solutions of the same concentration.
- Example 17 Comparison of the Air Stability of the Polymers PLEDs were produced using polymer P1 and the same polymer V1, on the one hand in a nitrogen atmosphere and on the other hand in air, and the electroluminescence of the devices thus obtained was investigated. The results are summarized in Table 3.
- Example 18 Voltage and voltage increase during operation
- PLEDs were produced with polymer P1 and comparative polymer V1, and the operating voltage was monitored when the devices were operated with a constant current density of 10 mA / cm 2 .
- the change in the operating voltage with time is shown in FIG. 1.
- the voltage required for a current density of 10 mA cm 2 is significantly lower for the polymer P1 according to the invention than for the comparison polymer V1. Furthermore, it can be seen from the figure that the voltage rise in the polymer according to the invention is significantly lower and even almost zero, while it is significantly higher in the comparative polymer. This is an important result since it shows that the polymer according to the invention is more stable to current than the comparison polymer.
