摘要： According to the invention, the surface of a substrate possessing an active hydrogen group is contacted with a chemical adsorbent containing a radical generation precursor group or metal ion capturing group within a molecule - also possessing a reactive functional group such as halosilyl or alkoxy silyl at its end - to form a chemical adsorption film by removing the unreacted chemical adsorbent. Radicals are then generated or magnetism is expressed on the chemical adsorption film. For example, when the diazo group on the film surface is irradiated with ultraviolet rays and transformed into carbene, an organic magnetic chemical adsorption monomolecular film is obtained. It may also be possible to form such a film by contacting the chemically absorbed film with a chemical adsorbent possessing the reactive functional group at its end, so that organic molecules possessing unpaired electrons derived from a metal or radical are oriented, forming a magnetic organic film.

摘要： An information recording layer on a substrate provides a method of recording information by selectively opening the rings of dicyclopentadiene skeletons, thus recording information by forming cyclopentadiene skeletons. The information recorded by the method can be erased by the cycloaddition of cyclopentadiene skeletons. Information can also be recorded or erased by incorporating or eliminating a metal ion from a selectively opened section of a ring of a dicyclopentadiene skeleton after forming an organic thin film comprising the dicyclopentadiene skeleton. Alternatively, after the formation of an organic thin film comprising a cyclopentadiene skeleton, a heterocycle or a benzene ring, a metal ion is incorporated or eliminated from a section between at least two rings of the cyclopentadiene skeleton, the heterocycle or the benzene ring. Thereafter, a metallocene skeleton or a skeleton analogous to the metallocene skeleton is formed or eliminated, thus recording or erasing information. The selective opening of a section of a dicyclopentadiene skeleton ring is carried out by heat or light. The readout of the information is performed by recognizing the cyclopentadiene skeleton, the metallocene skeleton, the skeleton analogous to the metallocene skeleton or the metal atom. The information recording layer of the invention is a chemically adsorbed monomolecular film 15 with a thickness at the angstrom level.

摘要： A durable and extremely water- and oil repellent ultra thin film is formed on the surface of a substates such as glass, ceramics, fabrics, fur and cloth by a dehydrochlorination reaction between a functional group such as a hydroxyl group or an imino group on the surface of the substrate. The coating film of the material comprises a plurality of chlorosilyl groups was formed on the surface of the substrate by dipping and holding the substrate comprising functional groups on its surface in a solution prepared by dissolving a material comprising fluorocarbon groups and a plurality of chlorosily groups in a non-aqueous solvent and drying the substrate which is then taken out from the solution in a substantially moistureless or low moisture atomosphere and removing the non-aqueous fluorocarbon-based organic solvent remaining on the substrate. Further, when the coating film is left in an atomosphere comprising moisture, i.e., humid air, the coating film is polymerized by a dehydrochlorination reaction between the coating film and the moisture in the atomosphere. The film is formed on the surface of the substrate containing hydroxyl groups, imino groups or carboxyl groups through -SiO- bonds or -SiN

摘要： A chemically adsorbed multilayer film is formed through the process of replacing a halogen atom on the surface of a chemically adsorbed film with an alkaline metal or changing the halogen atom to a Grignard group by Grignard reaction. This manufacturing method does not disrupt the molecules of the chemically adsorbed film, is easy to perform, low in cost and is safe. After replacing the halogen (for example, Br) on the surface of the film with an alkaline metal such as Li, a condensation reaction including a dealkalihalide reaction is promoted by contacting the chemically adsorbed film with an adsorbent, such as a chemical adsorbent - containing a halosilane group at one end of a molecule - dissolved in a nonaqueous solvent. A chemically adsorbed multilayer film is then formed by reacting the chemically adsorbed film with water after removing unreacted adsorbents using a nonaqueous solution.

摘要： According to the invention, molecules having conductive, photofunctional and other functions are secured by chemical bonds to a substrate via a chemically adsorbed monomolecular film by an adsorption process. The process comprises a step of contacting the substrate with a non-aqueous solution containing a material. The material includes a straight chain molecules having a plurality of chlorosilyl groups at both ends. A reaction occures between hydroxyl groups on the substrate surface and chlorosilyl groups at one of the ends of the material having the chlorosilyl groups. Prior to the reaction the substrate is washed with a non-aqueous organic solution by dipping the substrate in a non-aqueous solution containing molecules having a specific function for causing the reaction of the molecules with the chlorosilyl groups at the other end of the molecules having the chlorosilyl groups, thereby securing the molecules to the surface of the substrate.

摘要： A lubricating film of the invention is comprised of a chemically adsorbed monomolecular film, in which long-chain molecules are chemically bonded to at least one surface of a substrate via siloxane bonding, and layers of chemically adsorbed monomolecular film are formed on the surface of the previously formed chemically adsorbed monomolecular film after changing the groups at the end of chemical admolecules to monofunctional groups. The lubricating film has excellent endurance against sliding, with lubrication and anti-abrasion properties, and such properties of the film can be maintained for a long period. A chemically adsorbed monomolecular film can be formed on a substrate surface via covalent bonding (SiO-) by the dehydrochlorination reaction between active hydrogens on the substrate surface and the silane-based chemical adsorbent comprising dimethylsilyl groups. The substrate formed with the chemically adsorbed monomolecular film is then treated by an oxidation treatment, an alkaline treatment or an energy irradiation, thus changing the dimethylsilyl groups to the active hydrogen groups such as hydroxyl groups, imino groups or the like. The above-noted chemical adsorbent is contacted to the substrate surface, thus forming a chemically adsorbed multilayer film. Moreover, a long-chain hydrocarbon compound can be physically adsorbed to the surface of the chemically adsorbed multilayer film.
