A solution of t-butyllithium in pentane (1.74 mol/) was added dropwise to the solution over 20 minutes. As the solution is added dropwise, the color changes from yellow to orange. After the dropwise addition was completed, the temperature in the system was gradually raised to room temperature over 1 hour, and then lowered to -70°C again. Add 5 ml of dimethyldichlorosilane (1.26 g) to this solution.
A tetrahydrofuran solution was added dropwise over 10 minutes. After aging at -70℃ for 30 minutes and at 0℃ for 30 minutes,
The solvent was distilled off. The obtained residue was dissolved in benzene, the salt was filtered off, and then passed through a silica gel column to remove decomposed products. Almost pure di(9-anthryl)dimethylsilane of the present invention was obtained by recrystallization from a mixed solvent of benzene and n-hexane. Identification was based on proton nuclear magnetic resonance spectra ( 1H -NMR) and high-resolution mass spectra. The results are shown below.

As described above, the novel di(9-anthryl)dimethylsilane compound of the present invention produces [4+2] adducts with different colors and structures in high yield when irradiated with light, and the [4+2] adducts are Quantitative regeneration of raw materials by heating. Therefore, by utilizing this reversible change in color tone, a benzene solution (5 to 10% by weight) obtained by dissolving the compound of the present invention in benzene is applied onto a substrate and dried to form a film. When this is irradiated with a laser beam or the like, the local color tone changes and a difference in light reflectance occurs between the irradiated area and other areas. By generating and detecting this reflectance difference, information can be recorded and reproduced. Next, by heating the area where the color tone has changed with a laser beam, the color tone will return to its original state and the recorded information can be erased.

Further, the compound of the present invention undergoes a structural change when the color tone changes due to light irradiation. By utilizing the change in solubility in a solvent due to this structural change, the compound of the present invention can be used in a photoresist. For example, when a mask is placed on a thin film of the novel compound prepared by a method similar to that described above and irradiated with light, a difference in solubility in the solvent occurs between the masked portion and the unmasked portion. This thin film can be treated with a solvent to form a resist pattern.
