<p>The method of the present invention for forming a monomolecular membrane on a substrate comprises the steps of (1) mixing (a) at least one substance having a water-soluble polar head (hydrophilic portion) and a water-insoluble organic tail (hydrophobic portion) in the molecule, the head being ionizable into a cation when spread on water, and (b) at least one substance having a water-soluble polar head (hydrophilic portion) and a water-insoluble organic tail (hydrophobic portion) in the molecule, the head being ionizable into an anion when spread on water, to obtain a mixture, (2) developing the mixture on an aqueous subphase to form a monomolecular layer, and (3) transferring the monomolecular layer to a substrate while applying a surface pressure to the layer. According to the present invention, there can be formed a unidimensionally controlled membrane which develops a higher function than do the conventional two-dimensionally controlled membranes. Consequently, the method of the present invention can be applied, for example, to the formation of wiring patterns of a molecular level.</p> |
