Abstract

PURPOSE:To obtain such a high density recording medium which induces a chemical change or physical change in a molecular unit by providing the monomolecular film of a metallic chelate compd. having the N=N bond which desorbs metallic ions or metallic atoms by cistrans isomerization when applied with the rays of light or the cumulative film thereof and electrodes. CONSTITUTION:The chelate complex molecular film cumulated to the two layers consisting of cis-type chelate coordinate molecules 1 and metallic ions (or metallic atoms) 3 is formed on a glass substrate 5 on which a transparent electrode 7 is deposited by evaporation. The substrate constituted by laminating a fatty acid 4 on a glass substrate 5 on which another transparent electrode 7 is deposited by evapora tion is formed and is disposed to face the above-mentioned substrate. A bias voltage is applied between both electrodes and trans-type isomerizing light 6 consisting of the light such as UV rays are visible light which can supply the energy necessary for isomerization is irradiated thereto according to a certain pattern. Then, the photoisomerization reaction arises in the irradiated part where the transfer to the trans-type chelate coordinate molecules a rises to release the metallic ions 3 and to permit the recording of information. Monitor light 10 is then irradiated to a record ing medium and the change in the absorption of the light is read from transmitted light 9, 9' by which the recording is reproduced.

For example, regarding an optical recording medium that uses a thin film of an organic compound as a recording layer,
It is also disclosed in Japanese Patent Application Laid-Open No. 58-125246. All of them relate to laser recording media in which recording layers are made of organic dyes and recording and reproduction are performed using laser beams. In particular, the medium disclosed in JP-A-58-125248 uses a thin film of a cyanine dye represented by as a recording layer. A cyanine dye solution represented by the general formula CI) is coated on a plastic substrate to a thickness of 1000 Å or less, for example, about 300 A, using a spin coater or the like to form a thin film. If the molecular distribution and orientation within the film is random, light scattering occurs within the film upon light irradiation, and when viewed microscopically, the degree of chemical reaction that occurs each time the film is irradiated differs. Therefore, it is desirable for the recording medium to have a uniform molecular distribution and orientation within the film, and it is also required that the film thickness be as thin as possible in order to achieve high recording density. However, when using the coating method, the proof thickness is limited to about 300 people, and it is difficult to solve the problem that the molecular distribution and orientation within the film are random.

Even when producing a monomolecular film or a monomolecular layer stack of photopolymerizable olefin monomers, a manufacturing method is adopted in which a parent group or a hydrophobic group is introduced into a photoreactive compound and the photoreactive compound is directly supported on a substrate. Therefore, not only is it difficult to easily produce various functional films, but also there is a fear that photoreactivity may decrease due to the introduction of parent groups and hydrophobic groups. Furthermore, there is a problem that requires extremely complicated operations regarding the control of molecular orientation within the film plane, which is important when performing extremely advanced high-density recording.[Problems to be solved by the invention] The present invention eliminates the drawbacks of such conventional examples, and provides (1) a method for relatively easily producing various functional films, and (2) a method for producing various functional films in which the various functions of functional molecules can be realized when the film is made into a thin film. too,
3) A method for forming a film in such a way that the film is expressed without loss or deterioration; As a result of various studies on how to orient the particles with an ordered structure, the present invention was completed. Furthermore, by using such a film forming method, it has become possible to easily provide a high-sensitivity, high-resolution recording medium with high quality.

Next, to prevent this precipitate from freely diffusing on the aqueous phase and spreading too much, a partition plate (or float) is installed to limit the area of development and control the state of aggregation of the membrane material, and Obtain surface pressure ■. By moving this partition plate, the developed area can be reduced to control the state of aggregation of the film material, and the surface pressure can be gradually increased to set the surface pressure (2) suitable for producing a cumulative film. By gently raising and lowering the clean carrier vertically while maintaining this surface pressure, the chelate complex molecular film is transferred onto the carrier. A chelate complex molecule layer film is produced as described above, and a chelate complex molecule layer cumulative film having a desired degree of accumulation is formed by repeating the above-described operations.

In order to transfer the chelate complex molecular layer onto the carrier, in addition to the above-mentioned vertical dipping method, methods such as the horizontal deposition method and the rotating cylinder method can be used. The horizontal adhesion method is a method in which the carrier is brought into horizontal contact with the water surface and transferred, and the rotating cylinder method is a method in which a cylindrical carrier is rotated on the water surface to transfer the chelate complex molecular layer onto the surface of the carrier. In the vertical immersion method described above, when a carrier with a wood-philic surface is lifted out of water in a direction across the water surface, a layer of chelate complex molecules with the hydrophilic groups of the chelate complex molecules facing the carrier is formed on the carrier. When the carrier is moved up and down as described above, one layer of chelate complex molecules is stacked up in each step.The direction of the film-forming molecules is reversed between the pulling step and the dipping step, so according to this method, the distance between each layer is A Y-shaped film is formed in which the hydrophilic groups of the chelate complex molecules face each other, and the hydrophobic groups of the chelate complex molecules face each other. On the other hand, the horizontal deposition method is a method in which the carrier is brought into horizontal contact with the water surface and transferred, and a layer of chelate complex molecules with the hydrophobic groups of the chelate complex molecules facing the carrier side is formed on the carrier.
