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 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.
