<p>A monomer, if necessary, is dissolved in an organic solvent, and can be reacted at temperatures of not lower than the melting point and not higher than the boiling point of the organic solvent using, for example, an alkali or a suitable catalyst.</p>
<p>For example, known methods described in "Organic Reactions", vol. 14, p. 270-490, John Wiley & Sons, Inc., 1965, "Organic Reactions", vol. 27, p. 345-390, John Wiley & Sons, Inc., 1982, "Organic Syntheses", Collective Volume VI, p. 407-411, John Wiley & Sons, Inc., 1988, "Chemical Rev.", vol. 95, p. 2457 (1995), J.

<p>Chem., vol. 336, p. 247 (1994), Makromol. Chem., Macromol. Symp., vol. 12, p. 229 (1987) and the like can be used.</p>
<p>It is preferable that the organic solvent to be used is subjected to a deoxidation treatment sufficiently and the reaction is progressed under an inert atmosphere for generally suppressing side reactions though varying depending on compounds and reactions to be used.

<p>For carrying out the reaction, an alkali or suitable catalyst is appropriately added. These may be advantageously selected depending on the reaction to be used. As the alkali or catalyst, those dissolving sufficiently in a solvent to be used in the reaction are preferable.

In the case of the Heck reaction, monomers are reacted in the presence of a base such as triethylamine and the like using a palladium catalyst.</p>

<p>It may also be permissible that the temperature is raised up to near the boiling point of a solvent to cause ref lux. The reaction time is from about 1 hour to 200 hours.</p>
<p>In the case of the Grignard reaction, there are exemplified methods in which a halide and metal Mg are reacted in an ether-based solvent such as tetrahydrofuran, diethyl ether, dimethoxyethane and the like to give a Grignard reagent solution which is mixed with a monomer solution prepared separately, and a nickel or palladium catalyst is added while watching an excess reaction, then, the temperature is raised and the reaction is caused while ref luxing. The Grignard reagent is used in an amount of equivalent or more, preferably 1 to 1.5 equivalents, more preferably 1 to 1.2 equivalents based on monomers. Also in the case of polymerization by other methods than these methods, the reaction can be carried out according to known methods.</p>
<p>The reaction method is not particularly restricted and the reaction can be carried out In the presence of a solvent. The reaction temperature is preferably from -80 C to the boiling point of the solvent.</p>

<p>The method for producing the polymer thin film of the present invention may contain a process of orienting a polymer compound.</p>
<p>The polymer thin film containing a polymer compound oriented by this process shows improvement in electron mobility or hole mobility since main chain molecules or side chain molecules align along one direction.</p>
<p>As the method for orienting a polymer compound, there can be used methods known as a liquid crystal orientation technology, for example, methods described in "ekisho no kiso to oyo" (Shoichi Matsuinoto, Ichiyoshi Kadota collaboration, Kogyo Chosakai 1991), chapter 5, "kyoyudensei ekisho no kozo to bussei" (Atsuo Fukuda, Hideo Takezoe collaboration, Coronasha 1990), chapter 7, "ekisho vol. 3, no. 1 (1999), p. 3 to 16, and the like. Of them, a rubbing method, photo-alignment method, shearing method (shear stress applying method) and lifting coating method are simple and useful as an orientation method and easily used, and a rubbing method and a shearing method are preferable.</p>
<p>The rubbing method is a method of slightly rubbing the surface of a substrate with cloth and the like. As the substrate, glass, polymer film and the like can be used. As the cloth for rubbing a substrate, there can be used gauze, polyester, cotton, nylon, rayon and the like. When an orientation film is separately formed on a substrate, an orientation ability increases further. Here, mentioned as the orientation film are polyimide, polyamide, PVA, polyester, nylon and the like, and commercially available orientation films for liquid crystal can also be used. The orientation film can be formed by a spin coat method, flexographic printing and the like. The clothe used for rubbing can be appropriately selected according to the orientation film to be used.</p>
<p>The photo-alignment method is a method in which an orientation film is formed on a substrate and irradiated with polarized UV light or with UV light at inclined incident angle, to impart an orientation function. As the orientation film, mentioned are polyimide, polyamide, polyvinyl cinnamate arid the like, and commercially available orientation films for liquid crystal can also be used.</p>
<p>In the rubbing method or photo-alignment method, orientation can be attained by sandwiching an oriented polymer compound material between substrate subjected to the above-described treatment. In this case, it is necessary to set the substrate temperature at which the material is in liquid crystal phase or isotropic phase. The temperature may be set before sandwiching a polymer compound material between substrate, or after sandwiching. It is also permissible that the polymer compound material is only coated on a substrate subjected to the orientation treatment. Coating of a polymer compound can be conducted by methods in which a polymer compound is placed on a substrate and set at a temperature of Tg or higher or at which liquid crystal phase or isotropic phase is shown, and the polymer compound is coated toward one direction by a rod and the like, alternatively, a polymer compound is dissolved in an organic solvent to prepare a solution which is coated by spin coat, flexographic printing and the like.</p>
<p>The shearing method is a method in which on a polymer compound material placed on a substrate, another substrate is placed, and the upper substrate is shifted toward one direction under temperatures causing liquid crystal phase or isotropic phase. In this case, when substrate subjected to the orientation treatment as described in the abovedescribed rubbing method and photo-alignment method are used, those of higher degree of orientation are obtained. As the substrate, glass, polymer film and the like can be used, and the subject to be shifted by stress may not be a substrate but a metal rod and the like.</p>
<p>The lifting coating method is a technology in which a substrate is immersed in a solution of a polymer compound, then, lifter. The organic solvent to be used in the polymer compound solution and the lifting speed are not particularly restricted, and can be selected and adjusted according to the degree of orientation of the polymer compound.</p>
<p>The process for orienting a polymer compound includes a case of performing after a process of rendering a polymer compound into a thin film such as a rubbing method, a shearing method and the like and a case of performing simultaneously with a process of rendering a polymer compound into a thin film such as a lifting coating method and the like. Alternatively, a process of manufacturing an orientation film may be contained before a process of rendering a polymer compound into a thin film.</p>
<p>Since the polymer thin film of the present invention has electron transportability or hole transportability, it can be used for various polymer thin film devices such as organic thin film transistors, organic solar batteries, optical sensors, electrophotography photoreseptors, spatial light modulators, photo-refractive devices and the like by controlling transportation of electrons or holes injected from an electrode or charges generated by light absorption. When the polymer thin film is used for these polymer thin film devices, it is preferable to orient the film by an orientation treatment before use since then electron transportability or hole transportability is further improved.</p>
