Abstract: PURPOSE:To obtain the oriented film which can extremely adequately control the orientation of liquid crystal molecules by irradiating the surface of the high-polymer film on an electrode substrate with a high-intensity UV layer, thereby forming periodic patterns. CONSTITUTION:The surface of the high-polymer film of the electrode substrate of a liquid crystal display device is irradiated with the high-intensity UV laser to form the periodic patterns. Arom. polyether sulfone, arom. polyimide and arom. polyester are used as the high-polymer film. XeF, XeCl, KrF, ArF or F2 excimer laser is used as the UV layer. The beam is passed through a mask (metallic pattern) in order to form the periodic patterns. The swarf by the laser splashes at a high speed and does not stick. The cutting depth is controllable by a laser wavelength, effluence and pulse number. The ruggedness which is physically and chemically stable is thus formed.

Abstract: PURPOSE:To obtain an ultrathin organic film, by using a cyclodextrin derivative having a specified structural formula. CONSTITUTION:A cyclodextrin derivative represented by formula 1 (wherein R is a 4C or higher alkyl, X is a functional group bondable to at least two atoms, Y is hydrogen, an acyl or an ether group and n is an integer >=6). An ultrathin organic film can be prepared from this derivative by the following process. Namely, a thin film of said cyclodextrin derivative is formed on the surface of an aqueous solution and a solid substrate is allowed to pass through this film to deposit the cyclodextrin derivative thereon. Examples of said solid substrate include an ordinary glass plate, those formed by laminating monomolecular membranes of, e.g., stearic acid or arachic acid thereon, quartz, aluminum, calcium fluoride, etc.

Abstract: PURPOSE:To simplify the structure of a cell and to improve low-voltage driving, memory characteristic, etc., by preparing an electrochromic modifying electrode of a two-electron oxidation-reduction system formed of a chemically stable salt. CONSTITUTION:The compds. expressed by formulas I-IV are used for the electrochromic display device consisting of the electrolytic cell in which the electrode formed by modifying an org. compd. allowing a reversible change of the color by an electrochemical redox reaction is used as a working electrode. In formulas I-IV, X denotes respectively halogen, acetic acid, perchloric acid anion; R denotes an alkyl, acetyl group, aryl group, nitrogenous heterocylic group; R denotes a hydrogen atom., methoxy group; Ar, Ar' denote an aryl group, nitrogenous heterocylic group. The aryl group and the nitrogenous heterocylic group contain a condensed ring and substitution products of alkyl, methoxy, halogen, nitro, etc. The redox type org. compd. can be thereby fixed to the electrode surface and, therefore, the structure of the cell is simplified and the driving voltage is lowered.

Abstract: PURPOSE:To obtain the hyper thin film composed of an inclusion compd. of cyclodextrin and an org. molecule by incorporating a specific cyclodextrin derivative to the titled film. CONSTITUTION:The hyper thin film of the inclusion compd. of the cyclodextrin and the dye is formed by synthesizing a molecule which contains the cyclodextrin part as a hydrophilic group and a long chain hydrocarbon group as a hydrophobic group by substituting the primary alcohol part of the cyclodextrin with a functional group contg. the long chain hydrocarbon group, and by mixing an azo dye and said molecule in an org. solvent, and by spreading the obtd. mixture on the surface of water to form a stable monomolecular film composed of the cyclodextrin and the dye and the inclusion compd. thereof, and subsequently laminating said monomolecular film on a substrate. The hydrophobic group and the hydrophilic group which have an appropriate molecular volume and strength, and the balance thereof are important as the cyclodextrin derivative in order to form the stable monomolecular film on the surface of water. Said cyclodextrin derivative is shown by formula I wherein R is >=8C long chain hydrocarbon group, (n) is an integer of >=6.

Abstract: PURPOSE:To prompt the formation of J associated body and to transform a part of the area of thin film selectively to associate by controlling the associated state of org. dye molecules in Langmuir-Blodgett's film which is a typical example of org. ultra thin film by the impression of magnetic field. CONSTITUTION:A magnetic field is impressed to associated org. dye molecules in Langmuir-Blodgett's film which is a typical example of org. ultra thin film to prompt the formation of J associated body. An org. dye having the structure for forming the J associated body is used as the org. dye molecule. Suitable org. dye molecule is a molecule of cyanine dye, merocyanine dye, or squarylium dye. Further, the magnetic field to be impressed to the associated org. dye molecules is regulated to >=100 gauss. Thus, the formation of J associated body is prompted and selective transformation of a part of the area of thin film to associate has become possible.

Abstract: PURPOSE:To obviate the generation of dust and the rupture of films, etc., by subjecting thin films formed of org. molecules contg. arom. rings by using an LB method (Langmuir-Blodgette method) to a heat treatment to cause thermal decomposition polymn. thereby forming conductive or semiconductive thin films. CONSTITUTION:The thin films are formed of the org. molecules having the arom. rings by using the LB method. The thin films are then heat treated in a high vacuum or inert gaseous atmosphere to cause the thermal decomposition polymn., by which the org. thin films having both of a liquid crystal orienting function and a conductive or semiconductive function in combination are formed. The LB films obtd. in such a manner are used as liquid crystal oriented films 3. For example, two sheets of LB film accumulated substrates 4, 4 laminated with transparent electrodes 2 and the liquid crystal oriented films 3 successively on glass substrates 1 are disposed to face each other in such a manner that the immersion directions intersect orthogonally with each other and a spacer 5 is interposed therebetween to form a liquid crystal cell 6. A liquid crystal 7 is injected into the cell 6 and the cell is so formed that the electrodes 2 and 2 can be energized therebetween.

EXAMPLE:Tri-n-decylmethylumonium-bis[(4,5-dimercapto)-1,3-dithiol-2-on e]gold complex. USE:A display element, information memory device, ultrathin film switching element, wiring material for ultra-high-density LSI. PREPARATION:The organic complex of formula can be produced e.g. by reacting a methanol solution of 4,5-bis(benzoylthio)-1,3-dithiol-2-thione with metallic sodium, adding and reacting sodium tetrachloroaurate(III) dihydrate to the reaction product and reacting the product with tri-n- decylmethylammonium bromide. An electrically conductive ultrathin film is produced by forming an ultrathin film of the complex by Langmuir Blodgett method and oxidizing the film.
