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.
