TECHNICAL FIELD The present invention relates to a novel stilbene derivative, which can be used as an organic photoconductive material and a fluorescent brightener for electrophotography, and provides a material that is particularly useful as an organic photoconductive material for electrophotography. It is something. Prior Art Conventionally, many materials including poly-N-vinylcarbazole have been proposed as organic photoconductive materials for photoreceptors used in electrophotography. The "electrophotographic method" referred to here generally means that a photoconductive photoreceptor is first charged in a dark place by, for example, corona discharge, and then the electrostatic latent image is formed by selectively discharging the charge only in the exposed areas. This is one of the image forming methods in which an image is formed by visualizing this latent image using a developing means using toner or the like. The basic characteristics required of a photoreceptor in such an electrophotographic method are 1) to be charged to an appropriate potential in a dark place, 2) to have little discharge of charge in a dark place, and 3) to be able to withstand light irradiation. Examples include discharging charges more quickly. However, the reality is that conventional photoconductive organic materials do not necessarily satisfy these requirements. On the other hand, selenium and zinc oxide are known as photoconductive inorganic materials, and among them selenium is widely used in practical use. However, recently, in terms of the electrophotographic process, various demands have been placed on the photoreceptor. For example, in addition to the above-mentioned basic characteristics, there is also a demand for a flexible belt-like photoreceptor in terms of shape. However, in the case of selenium, it is generally difficult to create such shapes. Purpose An object of the present invention is to provide a novel stilbene derivative that is particularly useful as a photoconductive material, which eliminates the above-mentioned drawbacks of photoconductive materials for photoreceptors. Structure The present invention is based on the general formula () (In the formula, X represents a chlorine atom, R 1 represents a lower alkyl group or a benzyl group, and R 2 represents a benzyl group or a phenyl group.) Such stilbene derivatives have the general formula () [In the formula, X is a halogen atom, Y is

2に示す。A triphenylphosphonium group represented by [Formula] (wherein Z represents a halogen ion) or a dialkylphosphorous acid group represented by -PO(OR) 2 (herein, R represents a lower alkyl group)] The phenyl derivative represented by the following general formula () (In the formula, R 1 is a lower alkyl group or a benzyl group,
R 2 represents a benzyl group or a phenyl group. ) can be obtained by reacting with an aldehyde compound represented by: The phenyl derivative represented by the general formula () can be obtained by heating the corresponding halomethyl compound and trialkyl phosphite or triphenylphosphine directly or in a solvent such as toluene, tetrahydrofuran, or N,N-dimethylformamide. easily manufactured by Here, the trialkyl phosphite is preferably an alkyl group having 1 to 4 carbon atoms, particularly a methyl group or an ethyl group. The phenyl derivative represented by the general formula () thus obtained and the aldehyde compound represented by the general formula () are mixed at room temperature in the presence of a basic catalyst.
The reaction is carried out at a temperature of approximately 100℃. As basic catalysts, mention may be made of caustic soda, caustic potash, sodium amide sodium hydride and alcoholates such as sodium methylate and potassium t-butoxide. In addition, as a reaction solvent, methanol, ethanol, isopropanol, butanol, 2-methoxyethanol,
1,2-dimethoxyethane, bis(2-methoxyethyl) ether, dioxane, tetrahydrofuran, toluene, xylene, dimethyl sulfoxide, N,N-dimethylformamide, N-methylpyrrolidone, 1,3-dimethyl-2-imidazolidinone etc. can be mentioned. Among them, polar solvents such as N,N-dimethylformamide and dimethyl sulfoxide are preferred. The reaction temperature depends on 1) the stability of the solvent used against the basic catalyst, 2) the reactivity of the condensation components (compounds of general formulas () and ()), and 3) the reactivity as a condensing agent in the basic catalyst. Therefore, a wide range of choices can be made. For example, when using a polar solvent, the temperature is actually room temperature to 100°C, preferably room temperature to 80°C. However, when the reaction time is shortened or a less active condensing agent is used, higher temperatures may be used. Examples of novel stilbene derivatives according to the present invention obtained in this way are as follows. The novel stilbene derivative according to the present invention is
It is extremely useful as a photoconductive material in electrophotographic photoreceptors, and can be sensitized optically or chemically with sensitizers such as dyes and Lewis acids. It is also particularly useful as a charge transfer material in so-called functionally separated photoreceptors that use organic pigments or inorganic pigments as charge generation materials. Examples of the sensitizer include methyl violet,
Triallylmethane dyes such as crystal violet, Santen dyes such as rose bengal, erythrosine, and rhodamine B, azine dyes such as methylene blue, 2,4,7-trinitro-9-fluorenone, 2,4-dinitro-9-fluorenone, etc. can be mentioned. In addition, as organic pigments, CI Pigment Blue 25 (CI No. 21180), CI Pigment Red
41 (CI No.21200), CI Base Cred 3
(CI No. 45210), phthalocyanine pigments such as CI Pigment Blue 16 (CI No. 74100), CI Butt Brown 5 (CI No.
73410), CI Violet Dye (CI No.
73030), and perylene pigments such as Argo Scarlet B and Instance Scarlet R. Inorganic materials such as selenium, selenium-tellurium, cadmium sulfide, and α-silicon can also be used. Next, the present invention will be explained in more detail with reference to Examples. Example 1 4-chlorobenzylphosphonium chloride

The reaction mixture was diluted with 300ml of water. The precipitated powder was separated by filtration, washed with water, and dried to obtain a pale yellow powder. Yield: 37.8g (yield 92.0%), melting point: 137.0-139.0
It was warm at ℃. Recrystallization from a mixed solvent of toluene-n-hexane with a trace amount of iodine gave pale yellow needle-like crystals of 4-chloro-4'-N,N-dibenzylaminostilbene. The yield was 33.4g (yield 81.5%), and the melting point was
