## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an element which emits light by converting electric energy into light, and more particularly to an organic electroluminescent element which can be suitably used in the fields of display elements, back lights of liquid crystals, illumination light sources, exposing apparatus for electrophotography, labels, sign boards and the like.
2. Description of the Related Art
Since an electroluminescent element is a spontaneously emitting wholly solid element, has high visibility, and withstands impacts, wide application thereof is expected. Currently, an electroluminescent element using an inorganic fluorescent substance is popular and is used widely. Since such an electroluminescent element requires alternating current voltage in a range of 200 V or greater and 50 to 1000 Hz for driving, it has a problem in that a running cost thereof is high and luminance is insufficient. On the other hand, study of an electroluminescent element using an organic compound first started using a single crystal of anthracene or the like, but a film thickness of the element is as great as 1 mm, and the element requires a driving voltage of 100 V or greater. For that reason, as reported in Thin Solid Films, 94, 171(1982), thinning by a deposition method has been tried.
Light emission by these electroluminescent elements is a phenomenon in which electrons are injected from one electrode and holes are injected from another electrode, whereby, a light emitting material in an electroluminescent element is excited to a high energy level, and an excited light emitting substance releases, as light, extra energy produced when returned to a ground state. However, in these electroluminescent elements, a driving voltage is still as high as 30 V, densities of electron carriers and hole carriers present in a film are low, and a probability of production of photons by recombination of carriers is low. Therefore, sufficient luminance cannot be obtained, and these electroluminescent elements have not been put to practical use.
However, in 1997, Tang et al. reported in Appl. Phys. Lett., 51, 913(1987) and Japanese Patent Application Laid-Open (JP-A) No. 59-194393 that a high luminance of 1000 cd/m2 or larger can be obtained under a low driving voltage of around 10 V by an organic electroluminescent element. This organic electroluminescent element is a function separated-type organic electroluminescent element in which a hole transporting organic low-molecular compound, and a fluorescent organic low-molecular compound having electron transporting ability are successively deposited in order, as an extremely thin film, on a transparent substrate by a vacuum deposition method. Since this study by Tang et al., organic luminescence elements have been actively studied and developed.
These multilayer electroluminescent elements have a structure in which an organic light emitting substance and a charge transporting organic compound (charge transporting material) are deposited on an electrode, and the light emission by these elements is caused by recombination of holes and electrons, which are generated in both materials and move in the charge transporting material.
In this case, as the organic light emitting substance, organic dyes emitting fluorescene such as a 8-quinlinol aluminium complex and a coumarin compound are used. In addition, examples of the charge transporting material include diamino compounds such as N,N-di(m-tolyl) N,N′-diphenylbenzidine and 1,1-bis[N,N-di(p-tolyl)aminophenyl]cyclohexane, a 4-(N,N-diphenyl)aminobenzaldehyde-N,N-diphenylhydrazone compound and the like.
Organic electroluminescent elements using these organic compounds have high light emitting properties, but they have problems with respect to heat stability upon light emission and the storage stability. A thickness of a layer formed of an organic compound in an electroluminescent element is very thin, being as thin as several tens to several hundred of nanometers. Therefore, a voltage applied per unit thickness of a layer composed of this organic compound becomes very high, and the element is driven at a high current density of a few mA/cm2. Therefore, a large amount of Joule heat is generated from this layer. For this reason, a hole transporting low-molecular compound and a fluorescent organic low-molecular compound which are formed into an amorphous film are gradually crystallized as a temperature thereof is elevated and, finally, those compounds are melted, thereby causing a reduction in luminance and dielectric breakdown in many cases. Therefore, there is a problem in that a lifetime of the organic electroluminescent element is reduced. It is considered that the low heat stability of this organic electroluminescent element is derived from a low glass transition temperature of a material used in an organic electroluminescent element. That is, low-molecular compounds used as such a material have a low melting point and have high symmetry.
Thus, in order to solve the problem regarding heat stability, an organic electroluminescent element using N,N-di(1-naphthyl)N,N′-diphenylbenzidine with an α-naphthyl group introduced therein, as a material which has an improved glass transition temperature and can obtain a stable amorphous state, has been reported in Technical Study Report of the Electronic Information Communication Society, OME95-54(1995) and, for the same purpose, an organic electroluminescent element using a star burst amine has been reported in Proceedings of the 40th Applied Physics Related Associated Seminar 30a-SZK-14(1993). However, when these materials are used alone, since there is an energy barrier derived from ionization potential of a hole transporting material, hole injectability from an anode or hole injectability into a light emitting layer can not be satisfied. Further, in a 2-layered type element in which a hole transporting layer and a light emitting layer are deposited, a mutual diffusion phenomenon is caused. In addition, it is required that a material used in an organic electroluminescent element has heat stability with respect to heat treatment during a step of preparing an organic electroluminescent element, such as deposition, baking, annealing, wiring, sealing and the like, and with respect to change over time due to long term use of the organic electroluminescent element. For this reason, it is desired that a glass transition temperature of a material used in an organic electroluminescent element is even higher.
On the other hand, an electroluminescent element using a high-molecular material in place of a low-molecular compound has also been studied and developed. For example, in Nature, 357,577(1992) and JP-A No. 10-92576, there has been proposed an element using an electrically conductive polymer such as poly(p-phenylenevinylene) or the like. In addition, in Proceedings of the 42nd Polymer Discussion Meeting 20J21(1993), there has been proposed an element using a polymer in which triphenylamine is introduced on a side chain of polyphosphazene. Further, in Proceedings of the 38th Applied Physics Related Associated Seminar 31p-GI-2(1991), there has been proposed an element using a material in which an electron transporting material and a fluorescent dye are mixed into hole transporting polyvinylcarbazole.
These high-molecular materials have a comparatively higher glass transition points than that of a low-molecular compound. However, since poly(p-phenylenevinylene) is subjected to heat treatment after spin coating with a soluble precursor, defects are easily generated in a conjugated polymer on a main chain and light emitting properties are remarkably reduced. In addition, phosphazene has a high ionization potential, and thus, charge injecting properties are reduced. Further, polyvinylcarbazole has a high glass transition point, but has a problem due to traps. In addition, when a low-molecular compound is mixed into polyvinylcarbazole, the low-molecular compound acts as a plasticizer. For this reason, an organic electroluminescent element using these high-molecular materials has not yet caught up with the multilayer-type electroluminescent element using an organic low-molecular compound, in luminance, light emitting efficiency and the like.
In addition, a method of preparing an organic electroluminescent element is desirably a coating method in view of simplification of preparation, processibility, enlargement, cost and the like and, additionally, Proceedings of the 50th Applied Physics Society Seminar, 29p-ZP-5(1989) and Proceeding of the 51th Applied Physics Society Seminar, 28a-PB-7(1990) report that an organic electroluminescent element can also be prepared by a casting method. However, since a charge transporting material has deteriorated solubility in or compatibility with a solvent or a resin, the charge transporting material is easily crystallized and, thus, the above preparation methods lead to defects in preparation and properties of an organic electroluminescent element.

DETAILED DESCRIPTION OF THE INVENTION
The organic electroluminescent element of the present invention is an electroluminescent element, which comprises at least one pair of electrodes comprising an anode and a cathode, at least one of which having light transmissive, and at least one organic compound layer disposed between the electrodes, wherein the at least one organic compound layer contains at least one kind of non-conjugated polymer having terminal groups, and at least one of terminal groups of the non-conjugated polymer contains a fluorescent substance emitting fluorescence in a solid state.
In the invention, the “non-conjugated polymer” is a polymer having a repetition structure containing at least one σ bond on a main chain of the polymer, and is not particularly limited as long as at least one of terminal ends of the main chain has a fluorescent substance emitting fluorescence in a solid state (hereinafter, referred to as “fluorescent substance”).
In a non-conjugated molecule such as a molecule in which a plurality of light emitting compounds such as a fluorescent substance and the like continuously link together, an emitting intensity of the light emitting compound contained in the molecule is remarkably reduced as compared with a light emitting compound unlinked with any compound in some cases. In view of this point, it is preferable that the emitting compound is dispersed in a molecule. Since the non-conjugated polymer used in the invention has at least one non-connected fluorescent substance at terminal ends of a chain of the molecule, the aforementioned reduction in light emitting efficiency can be prevented and, as a result, sufficient light emitting intensity can be obtained.
Alternatively, a fluorescent substance may be added to any position other than terminal ends of a molecular chain of a polymer. However, when a non-conjugated polymer dose not have a fluorescent substance at terminal ends of the molecular chain, functional groups at terminal ends of the molecular chain may has an adverse effect on light emission of a fluorescent substance added to a part other than the terminal ends in some cases. In addition, when a charge moves on a molecular chain, functional groups at the terminal ends may suppress mobility of the charge in some cases.
However, since the non-conjugated polymer used in the invention has a fluorescent substance in place of at least one of functional groups at terminal ends of a molecular chain, it can sufficiently exert the light emitting properties of a non-connected fluorescent substance. In addition, when a charge moves on a molecular chain, mobility of the charge may be improved. Further, replacement of a functional group at a terminal end with a fluorescent substance is easy in synthesis of a non-conjugated polymer.
Further, the non-conjugated polymer used in the invention may have a fluorescent substance on both terminal ends. In this case, an emission color of the non-conjugated polymer can be easily adjusted to a desired color by choosing from combinations of fluorescent substances having different emission colors from each other. Such a non-conjugated polymer can be easily synthesized by copolymerization reaction.
Since the aforementioned non-conjugated polymer can be synthesized by selecting a structure of a part other than a fluorescent substance and adjusting a molecular weight, it is easy to obtain desired properties (e.g. heat stability, solubility in and compatibility with solvent and resin). For this reason, a non-conjugated polymer having excellent heat stability and film forming ability can be easily obtained.
As explained above, the non-conjugated polymer used in the invention has a high light emitting intensity, has high light emitting efficiency, has excellent charge moving properties, and is excellent in heat stability, and a film of the polymer can be easily made. Therefore, since in the organic electroluminescent element of the invention, the at least one organic compound layer contains the aforementioned non-conjugated polymer, light emitting intensity is high, the light emitting efficiency is high, a life of the element is long, and it is easy to make the element.
Examples of a fundamental structure of such a non-conjugated polymer include polymers comprising polyester, polyether, polyurethane, polyimide, polyamide, polyetherketone, polycarbonate, polysulfide, polyethersulfide, a silicon-containing polymer, and a germanium-containing polymer, or copolymers thereof. Among these, it is preferable that a fundamental structure of the non-conjugated polymer is any of polyester, polyether and polyurethane, in view of ease of synthesizing, heat stability, solubility in and the compatibility with a solvent and a resin, and the like.
In addition, the non-conjugated polymer may have a molecular chain on which a charge can move. In this case, it is preferable that the non-conjugated polymer is a hole transporting polymer.
It is preferable that the non-conjugated polymer as explained above comprises a repetition unit containing at least one partial structure selected from the group consisting of the following general formulas (I-1) and (I-2).
Since such a non-conjugated polymer is excellent in the heat stability during light emission, and solubility in and compatibility with a solvent and a resin, it is easy to prepare an organic electroluminescent element and, further, as an organic electroluminescent element, reliability of the light emitting property and a element life can be improved.

A non-conjugated polymer comprising a repetition unit at least one partial structure selected from the group consisting of the general formulas (I-1) and (I-2) is not particularly limited, but a polyester represented by the following formula (II-1) or (II-2), a polyether represented by the following general formula (III-1), and a polyurethane represented by the following general formula (IV-1) or (IV-2) are suitable.




In the general formulas (II-1) and (II-2), A1 represents at least one selected from the structures represented by the above general formulas (I-1) and (I-2), Y1 represents a divalent alcohol residue, Z1 represents a divalent carboxylic acid residue, m represents an integer of 1 to 5, and p represents selected from a range of 5 to 5,000.
In the general formula (III-1), A1 represents at least one selected from the structures represented by the above general formulas (I-1) and (I-2), and p represents an integer from 5 to 5,000.
In addition, in the general formulas (IV-1) and (IV-2), A1 represents at least one selected from the structures represented by the above general formulas (I-1) and (I-2), T represents a divalent straight hydrocarbon group having a carbon number of 1 to 6, or a divalent branched hydrocarbon group having a carbon number of 2 to 10, Y2 and Z2 represent divalent diisocyanate, alcohol or amine residue, m represents an integer from 1 to 5, and p represents an integer from 5 to 5,000.
The structure represented by A1 in the general formulas (II-1), (II-2), (III-1), (IV-1) and (IV-4) represents at least one selected from the structures represented by the general formulas (I-1) and (I-2), and two or more structures may be used, if necessary.
In addition, in the non-conjugated polymer used in the invention as explained above, at least one of terminal groups has a fluorescent substance emitting fluorescence in a solid state. Such a fluorescent substance may be an inorganic fluorescent substance or an organic fluorescent substance, an organic fluorescent substance is preferable in view of a magnitude of light emitting quantum efficiency and diversity of a material, and an organic fluorescent substance which has a further high quantum efficiency, is chemically stable, and has heat resistance is more preferable.
Examples of such a organic fluorescent substance include a compound having a substituted or unsubstituted monovalent benzene ring or a substituted or unsubstituted monovalent polynuclear aromatic hydrocarbon having an aromatic ring number of 2 to 10, a compound having a substituted or unsubstituted monovalent condensed aromatic hydrocarbon having an aromatic ring number of 2 to 10, and a compound having a substituted or unsubstituted monovalent aromatic heterocyclic ring.
More specifically, examples thereof include polyacene derivative compounds such as a naphthalene derivative, an anthracene derivative, a tetracene derivative, a perylene derivative, a pyrene derivative and the like, a styrylamine compound, a quinacridone derivative compound, a rubulene derivative compound, a coumarin derivative compound and a pyran derivative compound
In addition, since chelating metal complexes containing a metal such as Al, Zn, Be, Mg, Eu, Ga, Pt, Ir and the like have high fluorescent quantum efficiency, are chemically stable and have heat resistance, they can be suitably used as a fluorescent substance.
In addition, it is preferable that a maximum peak wavelength of fluorescent spectrum of a fluorescent substance is in the visible light region (380 nm to 700 nm). When a maximum peak wavelength is outside a range of the visible light region, sufficient light emitting intensity is not obtained in some cases.
Examples of such a fluorescent substance are shown in Tables 89 to 95, but the fluorescent substance used in the invention is not limited to them.

A weight average molecular weight Mw of the non-conjugated polymer used in the invention is not particularly limited, but when the non-conjugated polymer comprises a repetition unit containing at least one partial structure selected from the group consisting of the general formulas (I-1) and (I-2), it is preferable that the weight average molecular weigh Mw is in the range of 5000 to 300000.
Below, as a non-conjugated polymer, examples of polyester represented by the general formula (I-1) or (II-2) are shown in Tables 96 to 101, examples of polyether represented by the general formula (III-1) are shown in Tables 102 to 103, and examples of polyurethane represented by the general formula (IV-1) or (IV-2) are shown in Tables 104 to 107, but the polyester, the polyether and the polyurethane used in the invention are not limited to these examples.
Herein, the number in “A1” column of the “monomer” in Tables 96 to 107 corresponds to a compound having the number described in “structure” column in Tables 1 to 88 (specific examples of the above general formulas (I-1) and (I-2)). In addition, “m” means “m” shown in the general formulas (I-1) and (I-2). Hereinafter, an example (compound) with each number added thereto in Tables 96 to 107 is described as an example compound and, for example, an example with number 15 added thereto describes an exemplified compound (15).
In addition, in Table 96 to Table 101, example compounds, a partial structure of which is described only in “Y1” column, among “Y1” and “Z1” columns, mean polyester represented by the general formula (II-1). In addition, example compounds, a partial structure of which is described in both “Y1” and “Z1” columns, mean polyester represented by the general formula (II-2).
In addition, in Table 104 to Table 107, example compounds, a partial structure of which is described only in “Y2” column, among “Y2” and “Z2” columns, mean polyurethane represented by the general formula (IV-1). In addition, example compounds, a partial structure of which is described only in “Z2” column, among “Y2” and “Z2” columns, mean polyurethane represented by the general formula (IV-2).

A method of synthesizing the non-conjugated polymer used in the invention is not particularly limited, but the known methods can be utilized by combining them depending on a desired structure, and examples thereof are explained below. The following specific examples explain in detail the cases where a non-conjugated polymer comprising a repetition unit containing at least one partial structure selected from the group consisting of the above general formulas (I-1) and (I-2) is a polyester represented by the above general formula (II-1) or (II-2), a polyether represented by the above general formula (III-1), or a polyurethane represented by the above general formula (IV-1) or (IV-2).
I) In the Case of Polyester
When the non-conjugated polymer used in the invention is polyester represented by the above general formula (II-1) or (II-2), the non-conjugated polymer can be synthesized by polymerizing a monomer represented by the following general formula (II-3), for example, by the known method described in 4th edition, Experimental Chemical Course, vol. 28 (Maruzen Co., Ltd., 1992).

A′-A1-A′  (II-3)

In the general formula (II-3), A1 represents at least one selected from the structures represented by the general formulas (I-1) and (I-2), A′ represents a hydroxyl group, a halogen atom, or a group —O—R18, and R18 represents an alkyl group, a substituted or unsubstituted aryl group, or an aralkyl group.
That is, polyester represented by the above general formula (II-1) or (II-2) can be synthesized as follows:
1) When A′ is a hydroxy group, a divalent alcohol represented by HO—(Y—O)m—H is mixed with a monomer at an approximately equivalent amount, and this is polymerized using an acid catalyst. As an acid catalyst, catalysts which are used for a normal esterification reaction such as sulfuric acid, toluenesulfonic acid, trifluoroacetic acid and the like can be used, and are used in the range of 1/10,000 to 1/10 parts by weight, preferably 1/1,000 to 1/50 parts by weight relative to 1 part by weight of a monomer. In addition, as a solvent, it is preferable to use a solvent which can be azeotroped with water in order to remove water produced during polymerization, toluene, chlorobenzene, 1-chloronaphthalene and the like are effective, and the solvent is used in the range of 1 to 100 parts by weight, preferably 2 to 50 parts by weight relative to 1 part by weight of a monomer. A reaction temperature can be set arbitrarily, but in order to remove water produced during polymerization, it is preferable that a reaction is performed at a boiling point of a solvent.
After completion of the reaction, when a solvent was not used, the reaction solution is dissolved in a solvent which can dissolve the reaction solution. When a solvent was used, the reaction solution is added as it is dropwise to a poor solvent in which a polymer is hardly dissolved, such as alcohols such as methanol, ethanol and the like, acetone and the like, to precipitate polyester. Then, precipitated polyester is separated, washed with water or an organic solvent well, and is dried. Further, if necessary, polyester is dissolved in a suitable organic solvent, the solution is added dropwise to a poor solvent, and re-precipitating treatment for precipitating polyester may be repeated. Re-precipitating treatment is preferably performed while effectively stirring with a mechanical stirrer or the like. A solvent which dissolves polyester upon re-precipitating treatment is used in the range of 1 to 100 parts by weight, preferably 2 to 50 parts by weight relative to 1 part by weight of polyester. In addition, a poor solvent is used in the range of 1 to 1,000 parts by weight, preferably 10 to 500 parts by weight relative to 1 part by weight of polyester.
2) When A′ is halogen, polymerization is performed by adding an organic basic catalyst such as pyridine and triethylamine to a mixture solution obtained by mixing a monomer and a divalent alcohol represented by HO—(Y—O)m—H at an approximately equivalent amount. An organic basic catalyst is used in the range of 1 to 10 equivalent, preferably 2 to 5 equivalent relative to 1 equivalent of a monomer. As a solvent, methylene chloride, tetrahydrofuran (THF), toluene, chlorobenzene, 1-chloronaphthalene and the like are effective, and the solvent is used in the range of 1 to 100 parts by weight, preferably 2 to 50 parts by weight relative to 1 part by weight of a monomer. A reaction temperature can be set arbitrarily. After polymerization, the reaction is subjected to re-precipitating treatment as described above, and is purified.
In addition, in the case of a divalent alcohol having the high acidity such as bisphenol, an interface polymerization method may be used. That is, polymerization can be performed by adding a divalent alcohol to water, adding an equivalent amount of a base to dissolve them, and adding a monomer solution at the same equivalent as that of a divalent alcohol while vigorously stirring. Upon this, water is used in the range of 1 to 1,000 parts by weight, preferably 2 to 500 parts by weight relative to 1 part by weight of a divalent alcohol. As a solvent which dissolves a monomer, methylene chloride, dichloroethane, trichloroethane, toluene, chlorobenzene, 1-chloronaphthalene and the like are effective. A reaction temperature can be set arbitrarily and, in order to promote a reaction, it is effective to use a phase transfer catalyst such as ammonium salt, sulfonium salt and the like. A phase transfer catalyst is used in the range of 0.1 to 10 parts by weight, preferably 0.2 to 5 parts by weight relative to 1 part by weight of a monomer.
3) When A′ is —O—R18, transesterification is available for polymerization. Such transesterification can be performed by heating a reaction solution which include a monomer, an excessive amount of a divalent alcohol [represented by HO—(Y—O)m—H] relative to the monomer, and a catalyst such as titanium alkoxide, acetate or carbonate of calcium and cobalt, or oxide of zinc or lead. A divalent alcohol is used in the range of 2 to 100 equivalent, preferably 3 to 50 equivalent relative to 1 equivalent of a monomer. A catalyst is used in the range of 1/10,000 to 1 parts by weight, preferably 1/1,000 to I-2 parts by weight relative to 1 part by weight of a monomer. A reaction is performed at a reaction temperature of 200 to 300° C. and, after completion of transesterification from a group —O—R18 to a group —O—(Y—O)m—H, it is preferable to perform a reaction under reduced pressure in order to promote polymerization by leaving of HO—(Y—O)m—H. Alternatively, a reaction may be performed while removing HO—(Y—O)m—H by azeotropy under a normal pressure using a high boiling point solvent such as 1-chloronaphthalene which can be azeotroped with HO—(Y—O)m—H.
Alternatively, polyester may be synthesized as follows: In aforementioned respective cases, after a compound represented by the following general formula (II-4) is produced by a reaction by adding an excessive amount of a divalent alcohol and, by using this compound in place of a monomer represented by the above general formula (II-3), the compound may be reacted with divalent carboxylic acid or divalent carboxylic halide according to the aforementioned method, whereby, polyester can be obtained.




In the general formula (II-4), A1 represents at least one selected from the structures represented by the above general formulas (I-1) and (I-2), Y1 represents a divalent alcohol residue, and m represents an integer from 1 to 5.
4) Introduction of a fluorescent substance is not particularly limited, but there are following methods. That is, when A′ is a hydroxy group, a fluorescent substance can be introduced in a polymer by copolymerizing monocarboxylic acid of a fluorescent substance, or after a polymerization reaction for a polymer, using monocarboxylic acid of a fluorescent substance to react them. In addition, when A′ is halogen, a fluorescent substance can be introduced into a polymer by copolymerizing monoacid chloride of a fluorescent substance, or after a polymerization reaction for a polymer, using monoacid chloride of a fluorescent substance to react them. When A′ is —O—R18, a fluorescent substance can be introduced into a polymer by copolymerizing monoester of a fluorescent substance, or after a polymerization reaction for a polymer, placing monoester of a fluorescent substance to react them.
II) In the Case of Polyether
When the non-conjugated polymer used in the invention is polyether represented by the above general formula (III-1), the non-conjugated polymer can be easily prepared by condensing between molecules of a compound having a hydroxyl group represented by the following general formulas (III-2).

HO—A1-OH  (III-2)

In the general formula (III-2), A1 represents at least one selected from the structures represented by the above general formulas (I-1) and (I-2).
Polyether represented by the above general formula (III-1) can be specifically synthesized, for example, by the following method.
1) The aforementioned polyether can be synthesized by a method of heating and dehydration-condensing a monomer having two hydroxyl groups on both ends of a structure represented by A1, as in the above general formula (III-2). In this case, it is desirable that a monomer is heated to melt without using a solvent, and a reaction is performed under reduced pressure in order to promote a polymerization reaction by leaving of water. In addition, when a solvent is used, in order to remove water, it is effective to use a solvent which is azeotoped with water, for example, trichloroethane, toluene, chlorobenzene, dichlorobenzene, nitrobenzene, 1-chloronaphthalene and the like. In this case, a solvent is used in the range of 1 to 100 equivalent, preferably 2 to 50 equivalent relative to 1 equivalent of a monomer. In addition, a reaction temperature can be set arbitrarily, but in order to remove water produced during polymerization, it is preferable to perform a reaction at a boiling point of a solvent. When polymerization does not proceed, a solvent may be removed from a reaction system, and the reaction may be heated to stir at the viscous state.
2) The aforementioned polyether may be synthesized by a method of performing dehydration-condensation using, as an acid catalyst, protonic acids such as p-toluenesulfonic acid, hydrochloric acid, sulfuric acid, trifluoroacetic acid and the like, or Lewis acids such as zinc chloride and the like. In this case, an acid catalyst is used in the range of 1 to 1/10000 to 1/10 equivalent, preferably 1/1000 to 1/50 equivalent relative to 1 equivalent of a monomer. In order to remove water produced during polymerization, it is preferable to use a solvent which can be azeotroped with water. As such a solvent, toluene, chlorobenzene, dichlorobenzene, nitrobenzene, 1-chloronaphthalene and the like are effective, and they are used in the range of 1 to 100 equivalent, preferably 2 to 50 equivalent relative to 1 equivalent of a monomer. A reaction temperature can be set arbitrarily, but in order to remove water during a polymerization, a reaction is preferably performed at a boiling point of a solvent.
3) The aforementioned monomer can be also synthesized by a method using a condensing agent such as alkyl isocyanate such as cyclohexyl isocyanate and the like, alkyl cyanate such as cyclohexyl cyanate and the like, cyanate ester such as p-tolyl cyanate, 2,2-bis(4-cyanatophenyl)propane and the like, dichlorohexylcarbodiimide (DCC), trichloroacetonitrile and the like. In this case, a condensing agent is used in the range of I-2 to 10 equivalent, preferably 1 to 3 equivalent relative to 1 equivalent of a monomer. As a solvent, toluene, chlorobenzene, dichlorobenene, 1-chloronaphthalene and the like are effective, and they are used in the range of 1 to 100 equivalent, preferably 2 to 50 equivalent. A reaction temperature can be set arbitrarily, but it is preferable that a reaction is performed at room temperature to a boiling point of a solvent. Among synthesizing methods 1) to 3) explained regarding polyester, the synthesizing method 1) or 3) is preferable because isomerization and side reactions are hardly caused. In particular, the synthesizing method 3) is preferable because the reaction condition is milder.
After completion of the reaction, when a solvent was not used, the reaction solution is dissolved as it is in a solvent which can dissolve it. When a solvent was used, the reaction solution is added as it is dropwise to a poor solvent which hardly dissolves a non-conjugated polymer, such as alcohols such as methanol, ethanol and the like, acetone or the like, to precipitate polyether, and polyether is separate, washed with water or an organic solvent well, and dried. Further, if necessary, re-precipitating treatment be repeated in which polyether is dissolved in a suitable organic solvent, and the solution is added dropwise to a poor solvent to precipitate a monomer. Upon re-precipitating treatment, it is preferable to perform treatment while stirring effectively with a mechanical stirrer or the like. A solvent which dissolves a monomer upon re-precipitating treatment is used in the range of 1 to 100 equivalent, preferably 2 to 50 equivalent relative to 1 equivalent of polyether. In addition, a poor solvent is used in the range of 1 to 1000 equivalent, preferably 10 to 500 equivalent relative to 1 equivalent of polyether. Further, in the aforementioned reaction, it is possible to copolymerize using two or more kinds of, preferably 2 to 5 kinds of, more preferably 2 to 3 kinds of monomers. By copolymerizing different monomers, the electric property, the film forming property, the solubility and the fluorescent property can be controlled.
When a polymerization degree of polyether is too low, the film forming property is inferior, and a firm film is hardly obtained. On the other hand, a polymerization degree is too high, solubility in a solvent is reduced, and the processibility is deteriorated in some cases. Therefore, a polymerization degree is preferably in the range of 5 to 5000, more preferably in the range of 10 to 3000, further preferably in the range of 15 to 1000.
In order to introduce L1, as in a monomer, a hydroxyl group, that is, a terminal group R may be a hydrogen atom. However, when the polymer physical properties such as the solubility, the film forming property, the mobility and the like are adversely influenced, a terminal group R can be modified to control the physical property. For example, a terminal hydroxyl group can be alkyletherized with alkyl sulfate, alkyl iodide or the like. A specific reagent can be arbitrarily selected from dimethyl sulfate, diethyl sulfate, methyl iodide, ethyl iodide and the like, and is used in the range of 1 to 3 equivalent, preferably in the range of 1 to 2 equivalent relative to a terminal hydroxyl group. Upon this, a base catalyst can be used, and can be selected from sodium hydroxide, potassium hydroxide, sodium hydride, sodium metal and the like, and is used in a range of to 3 equivalent, preferably in the range of 1 to 2 equivalent relative to a terminal hydroxyl group.
A reaction can be performed at 0° C. to a boiling point of a solvent to be used. In addition, as a solvent used thereupon, a single solvent selected from inert solvents such as benzene, toluene, methylene chloride, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyl-2-imidazolidinone and the like, or a mixed solvent of 2 to 3 of them can be used. In addition, depending on a reaction, a quaternary ammonium salt such as tetra-n-butylammonium iodide and the like may be used as a phase transfer catalyst. Alternatively, a terminal hydroxyl group may be acylated using acid halide to convert a terminal group R into an acyl group.
Examples of acid halide are not particularly limited, but include acryoyl chloride, crotonoyl chloride, methacryloyl chloride, n-butyl chloride, 2-furoyl chloride, benzoyl chloride, cyclohexanecarbonyl chloride, enantyl chloride, phenylacethyl chloride, o-toluoyl chloride, m-toluoyl chloride, p-toluoyl chloride and the like. They are used in the range of 1 to 3 equivalent, preferably 1 to 2 equivalent relative to a terminal hydroxyl group. Upon this, a base catalyst can be used, and can be selected arbitrarily from pyridine, dimethylaminopyridine, trimethylamine, triethylamine and the like, and is used in the range of 1 to 3 equivalent, preferably 1 to 2 equivalent relative to acid chloride. Examples of a solvent to be used thereupon include benzene, toluene, methylene chloride, tetrahydrofuran, methyl ethyl ketone and the like.
A reaction can be performed at 0° C. to a boiling point of the solvent, preferably, in the range of 0° C. to 30° C. Further, acylation may be also performed using acid anhydride such as acetic anhydride and the like. When a solvent is used, specifically, inert solvents such as benzene, toluene, chlorobenzene and the like can be used. A reaction can be performed at 0° C. to a boiling point of the solvent, preferably, 40° C. to a boiling point of a solvent.
Besides, an urethane residue (—CONH—R′) can be introduced into a terminal end using monoisocyatnate. Specifically, monoisocyanate can be arbitrarily selected from benzyl isocyanate, n-butyl isocyanate, t-butyl isocyanate, cyclohexyl isocianate, 2,6-dimethyl isocyanate, ethyl isocyanate, isopropyl isocyanate, 2-methoxyphenyl isocyanate, 4-methoxyphenyl isocyanate, n-octadecyl isocyanate, phenyl isocyanate, I-propyl isocyanate, m-tolyl isocyanate, p-tolyl isocyanate, 1-naphthyl isocyanate and the like. Monoisocyanate is used in the range of 1 to 3 equivalent, preferably 1 to 2 equivalent relative to a terminal hydroxyl group.
Examples of a solvent to be used upon this include benzene, toluene, chlorobenzene, dichlorobenzene, methylene chloride, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone, 1,3-dimethyl-2-imidazolidinone and the like. A reaction can be performed at a temperature of 0° C. to a boiling point of a solvent to be used. When a reaction hardly proceeds, metal compounds such as dibutyltin (II) dilaurate, tin (II) octylate, lead naphthenate and the like, or tertiary amines such as triethylamine, trimethylamine, pyridine, dimethylaminopyridine and the like may be added as a catalyst.
In addition, introduction of a fluorescent substance is not particularly limited, but the following methods are exemplified. That is, a method of acylating a terminal hydroxyl group by a monoacid salt compound of a fluorescent substance, and a method of introducing an urethane residue into a terminal hydroxyl group by using monoisocyanate of a fluorescent substance can be applied.

When the non-conjugated polymer used in the invention is polyurethane represented by the above general formula (IV-1) or (IV-2), the non-conjugated polymer can be synthesized by polymerizing monomers represented by the following general formulas (IV-3) to (IV-6) by the known method, for example, described in 4th Experimental Chemical Course, vol. 28 (Maruzen Co., Ltd., 1992), New Polymer Experiment, vol. 2 (Kyouritsushupan) 1995 and the like.

HO—A1-OH  (IV-3)

NCO—A1-OCN  (IV-4)





H2N—A1-NH2  (IV-6)

In the general formulas (IV-3) to (IV-6), A1 represents at least one selected from the structures represented by the above general formulas (I-1) and (I-2).
Specifically, for example, when monomers represented by the general formulas (IV-3) and (IV-4) are used, polyurethane can be synthesized as follows.
When a monomer is a divalent alcohol represented by the general formula (IV-3), the monomer is mixed with diisocyanate represented by the OCN—Y—NCO at an equivalent amount and, when a monomer is diisocyanate represented by the general formula (IV-4), the monomer is mixed with a divalent alcohol represented by HO—Y—OH at an equivalent amount, whereby, polyaddition is performed.
As the catalyst, catalysts which are used in a reaction of synthesizing polyurethane by normal polyaddition, such as organometal compounds such as dibutyltin (II) dilaurate, dibutyltin (II) diacetate, lead naphthenate and the like can be used. In addition, when aromatic diisocyanate is used in synthesis of polyurethane, tertiary amines such as triethylenediamine and the like can be used as a catalyst. These organometal compounds and tertiary amines may be used by mixing them as a catalyst. An amount of a catalyst is in the range of 1/10,000 to 1/10 parts by weight, preferably 1/1,000 to 1/50 parts by weight relative to 1 part by weight of a monomer. Any solvents may be used as far as they dissolve a monomer and diisocyanate, or divalent alcohols. However, in view of the reactivity, it is preferable to use a solvent having the low polarity or a solvent forming no hydrogen bond to alcohols, and toluene, chlorobenzene, dichlorobenzene, 1-chloronaphthalene are effective. An amount of a solvent is in the range of 1 to 100 parts by weight, preferably 2 to 50 parts by weight relative to 1 part by weight of a monomer. A reaction temperature can be arbitrarily set.

Further, if necessary, re-precipitating treatment may be repeated in which polyurethane is dissolved in a suitable organic solvent, and the solution is added dropwise to a poor solvent, to precipitate polyurethane. Upon re-precipitated treatment, it is preferable to perform the treatment while effectively stirring with a mechanical stirrer or the like. A solvent which dissolves polyurethane upon re-precipitating treatment is used in the range of 1 to 100 parts by weight, preferably 2 to 50 parts by weight relative to 1 part by weight of polyurethane. In addition, a poor solvent is used in the range of 1 to 1,000 parts by weight, preferably 10 to 500 parts by weight relative to 1 part by weight of charge transporting polyurethane.
On the other hand, when monomers represented by the general formulas (IV-5) and (IV-6) are used, polyurethane can be synthesized as follows:
That is, when a monomer is bischloroformate represented by the general formula (IV-5), synthesis of polyurethane can be performed by mixing with diamine represented by 2HN—Y2—NH2 at an equivalent amount and conducting polycondensation. In addition, when a monomer is diamine represented by the general formula (IV-6), synthesis of polyurethane can be performed by mixing with bischloroformate represented by ClOCO—Y2—OCOCl at an equivalent amount and conducting polycondensation.

In addition, when basicity of diamine represented by 2HN—Y—NH2 is high, an interface polymerization method may be used. That is, polymerization can be performed by adding water to diamine, adding an equivalent amount of an acid to dissolve the material, and adding diamine and a solution of an equivalent amount of a monomer represented by the aforementioned general formula (IV-5) while vigorously stirring. Upon this, water is used in the range of 1 to 1,000 parts by weight, preferably 10 to 500 parts by weight relative to 1 part by weight of diamine.
As a solvent which dissolves a monomer, methylene chloride, dichloroethane, trichloroethane, toluene, chlorobenzene, 1-chlorohaphthalene and the like are effective. A reaction temperature can be arbitrarily set. In addition, in order to promote a reaction, it is effective to use a phase transfer catalyst such as ammonium salt, sulfonium salt and the like. A phase transfer catalyst is used in the range of 0.1 to 10 parts by weight, preferably 0.2 to 5 parts by weight relative to 1 part by weight of a monomer.
In addition, introduction of a fluorescent substance is not particularly limited, but following methods are exemplified.

In the case of a layer construction of the organic electroluminescent element shown in FIGS. 1 to 4, a metal, metal oxide, metal fluoride and the like which can be vacuum-deposited and has small work function for carrying out electron injection are used in a rear surface electrode 7.

The dispersed state for the aforementioned respective materials (non-conjugated polymer, light emitting material etc.) may be the state where materials are dispersed at a molecular level, or the state where fine particles such as fine crystals are dispersed. In the case of a method of forming a film using a coating solution, in order to obtain the state of dispersion at a molecular level, it is necessary to select a dispersing solvent in view of the dispersing property and the solubility of the aforementioned respective materials.
