- Example 4 As the organic molecular film of Example 4, a solution of 1 / 100th the concentration of the nonadecenyl trichlorosilane solution used for the formation of the self-assembled film of Example 3 (that is, a 0.01% by weight solution of nonadecyltrichlorosilane) An organic molecular film was formed by the same method as in Example 3 except that a self-assembled film was formed using Table 7 shows the absorption intensity area of the infrared absorption spectrum of Example 4 measured in the same manner as in Example 3. After forming the self-assembled film, the film thickness was measured using a scanning probe microscope and found to be about 1 nm (approximately the molecular length of nonadecenyltrichlorosilane).
- Example 4 As a comparison between Example 3 and Example 4, a film (Comparative Example 4) was prepared in which heptafluorobutyric acid was arranged on an aluminum substrate by the same method as Example 3 without forming a self-assembled film.
- Table 8 shows the absorption intensity area of the infrared absorption spectrum of Comparative Example 4 measured by the same method as in Example 3 above.
- the organic molecular film of Example 5 is the same as the forming method of Example 1, except that the constituent molecules of the self-assembled film and the dripping liquid dropped on the self-assembled film are different. Formed.
- Example 5 synthesized ⁇ - by a technique described in Japanese Patent No. 2889768 (3 Choi - Le) - decyl - 1 wt 0/0 solution (solvent trichlorosilane, hexadecane to Arudoritsu Chi Co., Ltd. Kanto I
- 2-propylthiophene manufactured by Aldrich was used as the dropping solution dropped onto the self-organized membrane. After forming a self-assembled film that also has ⁇ -(3-Che) -decyl-trichlorosilane force, and measuring the film thickness with a scanning probe microscope, it was about lnm (approximately ⁇ - ( 3—Cher) -decyl-trichlorosilane molecular length).
- the values of the absorption intensity areas in the table are all measured values of the organic molecular film containing 2-propylthiophene.
- the value obtained by subtracting the measured value of the monomolecular film (blank) consisting only of the tissue capsule was used.
- the infrared absorption spectrum ( ⁇ (3) of the 3000-2765 wave number (hereinafter also referred to as “second wave region”) of the organic molecular film of Example 5 was used.
- -Chenyl A peak derived from decyluteochlorosilane
- the absorption intensity area of the second wave number region derived from the self-assembled film did not change, so that ⁇ -(3 Cenyl) -decyl-trichlorosilane force
- the self-assembled membrane is thought to have a strong influence on the change caused by the incorporation of 2-propylthiophene, which is not changed by heating. From this result, it was found that the organic molecular film of Example 5 was a thin film in which 2-propylthiophene was inherently contained in a self-assembled film having ⁇ - (3-cenyl) -decyl-trichlorosilane force.
- Example 5 What should be noted in this Example 5 is the presence of 2-propylthiophene in a form inherent in the self-assembled film on the substrate, even though the substrate was heated above the boiling point of 2propylthiophene. It was that the infrared absorption spectrum which shows was observed. This consists of the long-chain alkyl group of ⁇ - (3 chalc) -decyl-trichlorosilane (first organic molecule) and the propyl group of 2-propylthiophene (second organic molecule) that make up the self-assembled film.
- Example 5 As a comparison with Example 5, two samples were formed on an aluminum substrate without forming a self-assembled film. A thin film (Comparative Example 5) in which lopyrithiophene was arranged in the same manner as in Example 5 was produced. Table 10 shows the absorption intensity area of the infrared absorption spectrum of Comparative Example 5 measured by the same method as in Example 5.
- the absorptivity of the second wave number region derived from 2-propylthiophene was observed at a substrate temperature of 25 degrees.
- the substrate temperature was 80 degrees, the absorption intensity in the second wavenumber region decreased, but an infrared absorption spectrum was observed.
- the substrate temperature was 125 degrees and when the substrate temperature was 170 degrees, absorption in the second wavenumber region was not observed.
- the absorption in the first wavenumber region derived from the thiophene ring of 2-propylthiophene was not observed when the substrate temperature was 80 ° C or higher. This indicates that 2-propylthiophene is evaporated by heating the substrate when a self-assembled film is formed.
- the organic molecular film structure of the present invention can be used as various functional molecular films, and in particular, can be expected to be applied to electronic devices.
