The monolayers are arranged two-dimensionally with a certain orientation such that the hydrophilic groups of the molecules are on the water surface and the hydrophobic groups are kept away from water, and then the monolayers are transferred to the surface of the solid substrate. This is repeated as many times as necessary to accumulate the monomolecular film on the substrate.

形成されているところが示されている。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 shows formation diagrams of several types of monomolecular films partitioned by partitions. In FIG. 1, the water surface is divided into partitions 1, 2, 3, and a barrier 4 which are linear,
It is shown that four types of monomolecular films a, b, c and d are formed in a stripe shape.

ものであって、本発明において必須のものでない。In the present invention, the partition may be provided so that the monomolecular films formed on the water surface are not mixed. The number of sections and monolayers may be any number as long as it is plural. The barrier provides a surface pressure necessary for forming a monomolecular film by narrowing the development area of the compound for forming a monomolecular film spread widely on the water surface. Note that this barrier is used for facilitating the production of a monomolecular film, and is not essential in the present invention.

い。In FIG. 1, a barrier 4 is provided independently in each section so that they can move independently.
If a suitable piston oil or the like is dropped and developed, it becomes easy to keep the surface pressures of the monomolecular films a to d substantially equal. In the present invention, the monolayers have substantially the same surface pressure so that the condition of the monolayer in each section can be maintained in a good and uniform state, and the stripes are clearly maintained even after the partition is removed. It is preferable that

に移動させて取除く態様をも包含するものである。FIG. 2 shows that the partition is removed from FIG. 1 to form four types of monomolecular films on the water surface. In the present invention, "removing a partition" means that there is no partition between adjacent monomolecular films, and therefore, the partition is simply lifted in the vertical direction and removed. In addition to the embodiments, the invention also includes an embodiment in which, for example, the partition is moved in the horizontal direction, or the monomolecular film is removed by moving it on a water surface having no partition.

る。In FIG. 3, the four types of monomolecular films of FIG. 2 are arranged so that each monomolecular film is arranged in a stripe shape and the entire width thereof is gradually narrowed to control the stripe width.
The formation of a striped monomolecular film is shown.

ない。FIG. 4 shows that two types of monomolecular films f and g are formed in a section where the water surface is divided by partitions 5 and 6 and a barrier 7. Reference numeral 8 denotes a Langmuir-type surface pressure sensor. Partition 5 in this state
If the surface pressures of the monomolecular films f and g are equal, the flow of the monomolecular film does not occur between the monomolecular films f and g.

る。FIG. 5 shows that the partition 5 is removed from FIG. 4 to form two types of monomolecular films on the water surface. In FIG. 5, a part of the monomolecular film f is transferred to the substrate 9 and removed, so that the monomolecular films f and g are placed on the water surface having no partition so as to compensate for the transferred amount. The molecular films f and g move so as to gradually narrow the entire width, and a controlled stripe-shaped monomolecular film is formed.

Also, it is not necessary to perform the transfer so as to have a pattern similar to the monomolecular film already accumulated on the substrate, and if desired, shift the pattern or transfer a monomolecular film of a completely different pattern. It can also be cumulative.

Essentially no different. Therefore, as the substance for forming a single molecule, the accumulating method or the accumulating operation, various conventionally known substances can be adopted and modifications can be made without departing from the spirit of the present invention.
