Phthalocyanine compounds, production method thereof, and near infrared ray absorption materials containing the same

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to novel phthalocyanine compounds, a method of producing the compounds, and near infrared ray (IR) absorption materials having a high solubility in solvents. The novel phthalocyanine compounds according to the present invention have an absorption in a near IR band of 600 to 1,000 nm, have an excellent solubility, and have an excellent light-fastness which is inherent to phthalocyanines. Therefore, the novel phthalocyanine compounds of the present invention provide an excellent effect when used for near IR absorption pigments for writing and reading signals in optical recording media using a semiconductor laser, liquid crystal display devices, optical character readers, etc.; near IR sensitizers; light-heat conversion agents in heat-sensitive transfer, heat-sensitive paper, heat-sensitive mimeographic plate, etc.; near IR absorption filters; asthenopic inhibitors; and photo-conductor materials. Furthermore, these phthalocyanine compounds exhibit excellent effects when used for photosensitive pigments for curing tumors, having a high texture transmissibility and a high absorption of rays of light in a long wavelength band, or for heat ray shielding materials for automobiles and building materials.
Furthermore, the novel phthalocyanine compounds of the present invention exhibit excellent effects as visible ray absorbing materials such as color separation filters for use in imaging tubes, liquid crystal devices, pigments for selective absorption filters of color cathode-ray tube (CRTs), color toners, inks for ink jet, bar code inks for preventing fake, and so forth.
2. Description of the Related Art
Recently, semiconductor lasers have been used as a light source for writing and reading signals in optical recording media such as compact disks, laser disks, optical memory devices, optical cards, etc., liquid crystal display devices, optical character readers, and so forth. Therefore, demands are increasing for materials absorbing near infrared rays (IR), or "near IR absorption pigments", which are used for photoconductor materials, near IR absorption filters, asthenopic inhibitors, light-heat conversion agents in heat-sensitive transfer, heat-sensitive paper, heat-sensitive mimeographic plate, etc., near IR sensitizers, photo-sensitive pigments for curing tumors, having a high texture transmissibility and a high absorption of rays of light in a longwave band, or heat ray shielding materials for automobiles and building materials. Among them, intensive studies have been made on phthalocyanine type compounds which are stable to light, heat, temperature, etc., and have a high fastness, to control their absorption wavelengths in accordance with intended applications, or to dissolve them in solvents in accordance with the intended applications.
As devices have become diversified in recent years, pigments having various absorption characteristics in accordance with applications have been desired. Nevertheless, it has been difficult to control the absorption wavelengths of the phthalocyanine type compounds. The pigments must be converted to a thin film without complicated steps such as vacuum evaporation or dispersion in a solvent, and in this case, a solvent which does not corrode substrates used for the devices must be used. Furthermore, the pigments must be dissolved in the resins used therewith. For these reasons, pigments capable of being dissolved in high concentrations in a variety of solvents in accordance with the applications have been required, but most of the phthalocyanine type compounds are insoluble in solvents.
Phthalocyanine compounds having solubility, which may be advantageous from the aspect of practical application, are disclosed recently. For example, 3,6-octaalkoxyphthalocyanine is known from Japanese Unexamined Patent Publication (KOKAI) No. 61-223056, but this compound involves problems such that control of the absorption wavelength is limited to a low wavelength side, and that an economical phthalocyanine cannot be obtained because the production process is complicated.
Japanese Unexamined Patent Publication (KOKAI) Nos. 60-209583, 61-152685, 63-308073 and 64-62361 disclose those compounds which improve solubility, and at the same time, expand the absorption wavelength to a longer wave length side by introducing a large number of thioether groups into the phthalocyanine skeletal structure for substitution. Among them, Japanese Unexamined Patent Publication (KOKAI) Nos. 60-209583 and 61-152685 disclose synthesis examples wherein the thioether groups are introduced into the phthalocyanine skeletal structure, particularly into the 3,6-positions. This method obtains the phthalocyanine compound having the thioether group at the 3,6-positions by heating a phthalocyanine compound having chlorine atoms at the 3,6-positions of the phthalocyanine skeletal structure and an organic thiol compound in a quinoline solvent in the presence of KOH. Since the yield is as low as about 20% to about 30%, however, this method has a problem of a poor production efficiency. Moreover, the solubility is still insufficient and the range of the absorption wavelength is limited.
Japanese Unexamined Patent Publication (KOKAI) Nos. 60-209583, 61-152685 and 64-62361 disclose Synthesis Examples wherein eight to sixteen thioether groups are introduced into the phthalocyanine skeletal structure.
This method obtains phthalocyanine having eight to sixteen thioether groups at the benzene ring of the phthalocyanine skeletal structure by heating a phthalocyanine compound having eight to sixteen chlorine and/or bromine atoms at the benzene ring of the phthalocyanine skeletal structure with an organic thiol compound in a quinoline solvent in the presence of KOH. The yield, however, is from about 20% to about 30% and the problem of a poor production efficiency remains unsolved, in the same way as described above.
Namely, since the substitution efficiency of the chlorine or bromine atoms to the thioether groups is low, the production yield becomes low, as well. Accordingly, an unreacted phthalocyanine in which the thioether groups have not been substituted with the chlorine atoms, or an unreacted phthalocyanine in which the thioether groups have been partially substituted with chlorine atoms, is generated. It is practically difficult to separate these unreacted phthalocyanine compounds from an intended phthalocyanine compound. For this reason, substantially only phthalocyanine mixtures having various compositions can be obtained.
Further, Japanese Unexamined Patent Publication (KOKAI) No. 64-62361 describes compounds as "polythiol substitution, mixed, condensed type phthalocyanine composition" even after separation using a silica gel, and admits that unreacted compounds remain. If a part of the chlorine atoms are left, solubility drops remarkably, and this leads to the drawback that the pigment cannot be easily dissolved and converted to a thin film as an IR absorption pigment, or other uses such as visible light absorption filter.
The method described in Japanese Unexamined Patent Publication (KOKAI) No. 63-308073 obtains a phthalocyanine compound at a yield of 42% by heating monobromotetradecachlorophthalocyanine and an organic thiol mixture comprising 2-aminothiophenol and 4-methylphenylthiol in a DMF solvent in the presence of KOH. Since in this method different organic thiol mixtures are simultaneously added and reacted, however, a resulting phthalocyanine mixture comprises phthalocyanines having different combinations of substituents, and therefore homogeneous product cannot be obtained. Accordingly, the application of the reaction product to those applications requiring the control of the absorption wavelength, such as the use as ink for cyan color ink jet, or as a near IR absorption pigment, is limited, for example. Although the reaction product has a solubility, its solubility is not yet sufficient for thin film formation or for dissolution in a resin.
Japanese Unexamined Patent Publication (KOKAI) Nos. 64-42283 and 3-62878 propose near IR absorption pigments having alkoxyl groups and alkylthio groups introduced into the phthalocyanine nucleus. Nevertheless, since most of these products are derived from starting materials having the substituent groups at the 3,6-positions, which have low practical utility, they involve the problem of practical applicability. The solubility of the product remains at a low level, and there is a limit to the derivation of phthalocyanines having controlled absorption wavelengths. To introduce the substituent groups into the 4,5-positions, the reference methods derive phthalocyanines from the starting materials in which the 4,5-positions are chlorinated. Accordingly, due to this low substitutivity, chlorine atoms, as a factor lowering the solubility, remain in the product.
Further, phthalocyanines soluble in alcohols are described in Japanese Unexamined Patent Publication (KOKAI) No. 63-295578. According to this reference, substituted thiocopper phthalocyanine mixtures obtained by reacting monobromo-tetradecachlorocopper phthalocyanine with an organic thiol mixture consisting of 2-aminothiophenol and 4-methylphenylthiol, such as hepta(4-methylphenylthio)-tetra(1-amino-2-thiophenyl-1,2-ylen)-copper phthalocyanine, is sulfonated by fuming sulfuric acid to obtain a phthalocyanine having ten sulfonic acid groups on an average, and the reaction product is then treated with a basic material such as tetrabutylammonium salt to convert them to sulfonamide groups, etc., and thus phthalocyanines having solubility in alcoholic solvents are obtained.
This method, however, involves the following problems.
The chlorine atoms are likely to partially remain, and if they remain, the solubility of the compounds drops remarkably.
Phthalocyanines are obtained as a mixture, and when the mixture is used as the near IR absorption pigment, the uniform characteristics cannot be obtained. Therefore, its application is limited.
The production process is extremely complicated, and the yield at each production step is low.
Since the sulfonation reaction is carried out in an aqueous system and then, the reaction product is purified by dialysis, this method involves the problems yet to be solved as an industrial production method.
To solve these problems, in Japanese Patent Application Nos. 1-209599, 2-125518 and 2-144292, the inventors of the present invention attempted to extend the absorption to a longer absorption wavelength and to improve solubility in solvents by selectively replacing fluorine atoms of octadecafluoropphthalocyanine with alkylthio groups or arylthio groups, and obtained certain effects. However, compounds having higher solubility are desired and an absorption wavelength, too, is desired to be extended to a longer wavelength.

In the production method 1 of the novel phthalocyanines according to the present invention, fluorine-containing phthalonitrile as the starting material can be synthesized preferably in accordance with the following scheme (1) or (2). The solvents used for the synthesis in each of the following schemes are inert solvents such as nitrobenzene, acetonitrile, benzonitrile, etc., or aprotonic polar solvents such as pyridine, N,N-dimethylacetoamide, N-methyl-2-pyrolidinone, triethylamine, tri-n-butylamine, dimethyl-sulfone, sulforan, etc.
Preferred condensing agents are organic bases such as triethylamine, tri-n-butylamine, etc., and potassium fluoride. Nucleophilic substitution reagents such as aniline, toluidine, anisidine, n-butylamine, n-octylamine, etc., also can be used as the condensing agent. These synthesizing methods have been disclosed by the inventors of the present invention, in Japanese Patent Application Nos. 63-65806, 1-103554, 1-103555 and 1-209599. ##STR17## wherein Y has the same meaning as in the general formula (II).
Any solvents can be used as the organic solvent used in the method (1) of producing novel phthalocyanine according to the present invention as long as they are inert solvents not having a reactivity with the starting materials. Examples of such organic solvents are inert solvents such as benzene, toluene, xylene, nitrobenzene, monochlorobenzene, dichlorobenzene, trichlorobenzene, chloronaphthalene, methylnaphthalene, ethylene glycol, benzonitrile, etc., or aprotonic polar solvents such as pyridine, N,N-dimethylformamide, N,N-dimethylacetoamide, N-methyl-2-pyrolidinone, triethylamine, tri-n-butylamine, dimethylsulfone, dimethyl sulfoxyde, sulforan, etc., and preferred are chloronaphthalene, trichlorobenzene, benzonitrile, and N-methyl-2-pyrodinone.
In the production method (1) of the novel phthalocyanine of the present invention, phthalonitrile represented by the general formula (II) is preferably used in an amount of 2 to 30 parts by weight on the basis of 100 parts by weight of the organic solvent. The metal compound represented by the general formula (III) is preferably used in an amount of 0.20 to 0.35 mole, preferably 0.25 to 0.30 mole, on the basis of one mole of phthalonitrile represented by the general formula (II).
The reaction temperature is preferably within the range of 100.degree. to 250.degree. C., and particularly preferably within the range of 120.degree. to 200.degree. C.
The reaction solvents used in the method (2) of producing the novel phthalocyanine of the present invention are inert solvents such as nitrobenzene, monochlorobenzene, dichlorobenzene, trichlorobenzene, chloronaphthalene, benzonitrile, etc., or aprotonic polar solvents such as pyridine, N,N-dimethylacetoamide, N-methyl-2-pyrolidinone, triethylamine, tri-n-butylamine, dimethylsulfone, dimethyl sulfoxyde, sulforan, etc. Preferred are benzonitrile, N,N-dimethyl-acetoamide, N-methyl-2-pyrolidinone, triethylamine, and tri-n-butylamine.
In the production method (2) of the novel phthalocyanine of the present invention, phthalocyanine represented by the general formula (IV) is preferably used in an amount of 2 to 30 parts by weight on the basis of 100 parts by weight of the organic solvents. The nucleophilic substitution compound represented by the general formula (V) is preferably used in an amount of 1 to 1,000 mol parts on the basis of one mole part of phthalocyanine represented by the general formula (IV), particularly preferably within the range of 2 to 300 mole parts. When these nucleophilic substitution compounds are liquid under the condition of the use, the starting materials can be used, as such, as the solvent without effecting a dilution by using the organic solvents described above.
The reaction temperature is preferably within the range of 40.degree. to 250.degree. C., particularly preferably 80.degree. to 200.degree. C.
Among the phthalocyanine compounds represented by the general formula (I) of the present invention, phthalocyanines having the phenyl group which is substituted by the alkylcarbonyl group, can be converted to the carboxyl group by the hydrolysis for example by heating in an aqueous sulfuric acid solution.
The production process (3) of the present invention provides a fluorine-containing phthalocyanine of the present invention represented by the formula (VI). The phthalocyanine (VI) can be obtained by sulfonating a fluorine-containing phthalocyanine represented by the formula (VII). In this method, as sulfonating agents, sulfuric acid, fuming sulfuric acid, sulfur trioxide, chlorosulfuric acid, fluorosulfuric acid, amidesulfuric acid, and sulfur trioxide complex are mentioned. Preferably, sulfuric acid, fuming sulfuric acid, sulfur trioxide, sulfer trioxide complex, chlorosulfuric acid and fluorosulfuric acid are used, and especially chlorosulfuric acid is preferable.
The organic solvents used in the Production Process (3) may be any solvents as long as they can dissolve the starting materials or can form a slurry. Examples of such solvents include halogen type solvents such as dichloromethane, chloroform, carbon tetrachloride, 1,2-dichlorethane, 1,1,2-trichlorethane, 1,1,2,2-tetrachloroethane, etc., aromatic solvents such as nitrobenzene, benzonitrile, etc., and carbon disulfide. Particularly preferred are the halogen type solvents such as dichloromethane, 1,2,2-dichloromethane, chloroform, carbon tetrachloride, 1,1,2,2-tetrachloroethane, etc., because they have a high solubility for the starting materials and can smoothly carry out the sulfonation reaction.
The reaction temperature is selected appropriately in accordance with the kind of the starting materials, the solvent, and other conditions, but is generally selected within the range of room temperature to 200.degree. C., preferably from 40.degree. C. to 150.degree. C.
The novel fluorine-containing phthalocyanine compound of the general formula (VI) produced by the Production Process (3) has high solubility in organic solvents, particularly in alcoholic solvents. Examples of the alcoholic solvents are C1 to C12 straight chain or branched chain alcohols such as methanol, ethanol, propanol, etc.; cellosolves such as ethyl cellosolve; glycols such as monoethylene glycol, diethylene glycol, etc.; diacetone alcohol; and halogenated alcohols such as tetrafluoropropanol.
In the phthalocyamine compound of the general formula (VI), the aryl group in the starting phthalocyanine is sulfonated to provide a suitable solubility in the alcoholic solvent. In the present invention, when the sulfonic acid group per se is introduced into phthalocyanine, solubility in the alocholic solvent becomes high, but the solubility can be improved further by reacting the sulfonic acid group with ammonia or with organic amines to convert it to an ammonium salt or a sulfone amide group.
These fluorine-containing phthalocyanine compounds also have a solubility in water. To further improve the solubility in water, it is effective to react the sulfonic acid group with a metal such as an alkali metal to convert it to a metal salt of the sulfonic acid group.
The fluorine-containing phthalocyanine (general formula (VII)) as a starting material of the production process (3) can be synthesized by any of the following synthesis methods (1) to (3). Among these synthesis methods, the first step of the methods (1) and (3), the second step of the method (1) and the second step of the method (3) have been disclosed in Japanese Patent Application Nos. 63-65806, 1-103554, 1-103555 and 1-209599, by the inventors of the present invention. ##STR18##
It is possible to use nitriles such as acetonitrile, and potassium fluoride, etc., as a condensing agent in the first step of each of the synthesis methods (1), (2) and (3). The reaction condition in the first step of the synthesis method (2) is the same as that of the first step in the synthesis method (1) except that the feed ratios of ROH, KF and tetrafluorophthalonitrile are different.
In the synthesis methods (2) and (3), it is also possible to mitigate the reaction condition of the first step in such a manner that the 4-position or the 5-position is not completely substituted by OR or SR but a fluorine atom partially remains, and to use this reaction product as the starting material of the second step. In these cases, the reaction product containing unsubstituted fluorine atoms at the 4- and 5-positions besides the fluorine atoms of the 3- and 6-positions, exists in phthalocyanines as the intended final reaction product, but such a product may be contained within the range which does not exert an adverse influence on properties such as the solubility.
Phthalocyanines of the types A), B) and C) of the definite examples given above among the phthalocyanine compounds of the general formula (I) are highly soluble in organic solvents, particularly in alcoholic type solvents and ketone type solvents such as straight-chain or branched chain alcohols as typified by methanol, ethanol, propanol, etc.; cellosolves such as ethyl cellosolve; glycols such as monoethylene glycol, diethylene glycol, etc.; diacetone alcohol; halogenated alcohols such as tetrafluoropropanol; acetone, and methyl ethyl ketone. This is due to the synergistic effect of the fluorine atoms substituted to the phthalocyanine nucleus and the functional group. Moreover, various absorption wavelengths can be controlled broadly by selecting the number of the fluorine atoms, the kind of the substitution groups and the center metal.
The phthalocyanine of the type D) of the definite example given above is highly soluble in organic solvents, particularly in hydrocarbon solvents such as benzene, toluene and xylene. This is due to the synergistic effect of the fluorine atoms and the functional group substituted on the phthalocyanine nucleus. Moreover, the absorption wavelength can be widely controlled by selecting the number of the fluorine atoms, the kind of substituent groups, and the center metal.
When compared with known phthalocyanine compounds soluble in the alcoholic solvent (e.g. the compounds disclosed in Japanese Unexamined Patent Publication (KOKAI) No. 63-295578, the above-mentioned type E) compound of the present invention has a higher solubility in the alcoholic solvent, even though the sulfonated product is not converted further to a sulfone amide. The compound of the present invention, of course, also can have a higher solubility in the alcoholic solvent when converted to a sulfone amide. The compound of the present invention has an absorption in the near IR band of 600 to 1000 nm.
It is believed that these unique functions are brought about by the cooperation between the two fluorine atoms at the 3,6-positions of the phthalocyanine ring, and the fluorine atom, the ether aryl group, the thioether aryl group at the 4-position or the 5-position and the sulfonic acid group bonded to them.
According to the production method of the present invention, a molecular design of compounds having different near IR absorption wavelength band or solubility in accordance with the intended applications becomes possible, and since a complicated production step is not necessary in this case, the present invention is industrially advantageous. Namely, the present invention can introduce desired substituents into the phthalocyanine ring in accordance with the intended object, and further, can produce efficiently phthalocyanine having a high purity. The novel compound of the present invention does not contain the chlorine atom and the bromine atom that lower the solubility, as described in Japanese Unexamined Patent Publication (KOKAI) No. 63-295578, and the fluorine atoms in the compound of the present invention have the effect of improving the solubility.
As described above, the novel compounds of the present invention can control the absorption wavelength within the absorption wavelength band of 600 to 1,000 nm in accordance with the object, and have a high solubility in solvents in accordance with the application, and in both hydrophilic solvents and lipophilic solvents; they also have the excellent light-fastness inherent to phthalocyanine. Therefore, the novel compounds of the present invention can be used as the near IR absorption pigment in fields in which this has not been accomplished by the prior art techniques.
