Examples
The following describes in detail examples of the present invention, but the present invention is not limited thereto.
Example 1
(1) Synthesis of 3, 3 ', 5, 5 ' -tetraacetylenyl-1, 1 ' -diamantane
In a 1000mL four-necked flask equipped with a thermometer, a stirrer and a reflux tube, 14g (0.6mol) of sodium metal and 600mL of n-octane were charged, and the internal temperature was cooled to 0 ℃. While stirring vigorously, a solution obtained by dissolving 64.5g (0.3mol) of 1-bromoadamantane in 300mL of n-octane in advance was slowly added dropwise. During the dropping, the internal temperature is maintained at 0 ℃ to 5 ℃. After the completion of the dropwise addition, the reaction was continued for 1 hour unless the temperature was raised. Then, about 1500mL of cold water was poured, and the crude product was filtered, washed with pure water, and dried. Further, the crude product was recrystallized from hot hexane. The obtained recrystallized product was dried under reduced pressure to obtain 32.6g of a product. The absorption of Br group (in the vicinity of 690-515 cm-1) was lost by IR analysis, and the molecular weight was 270 by mass analysis, from which it was confirmed that the product was 1, 1' -diamantane.
Into a 2000mL four-necked flask equipped with a thermometer, a stirrer and a reflux tube, 700mL of carbon tetrachloride and 70g (0.44mol) of bromine were charged, and 54.1g (0.2mol) of the 1, 1' -diamantane obtained above was gradually added with stirring. When adding, the internal temperature is maintained at 20 ℃ to 30 ℃. After the addition, the reaction was continued for 1 hour, unless the temperature was increased. Then, about 2000mL of cold water was poured, and the crude product was filtered, washed with pure water, and dried. The crude product was recrystallized from hot ethanol. The obtained recrystallized product was dried under reduced pressure to obtain 65.0g of a product. The absorption of the bromo group was found to be 690 to 515cm-1 by IR analysis, and the molecular weight was 586 by mass analysis, from which it was confirmed that the product was 3, 3 ', 5, 5 ' -tetrabromo-1, 1 ' -diamantane.
In a flask, 20g (34mmol) of 3, 3 ', 5, 5 ' -tetrabromo-1, 1 ' -diamantane obtained above and 18mL (256mmol) of vinyl bromide were dissolved in 120mL of methylene chloride, and 3.0g (22mmol) of aluminum (III) chloride was added dropwise under dry nitrogen at-15 ℃ and the solution was stirred for 1 hour. Further, 20mL of water was added dropwise at-15 ℃ and the mixture was returned to room temperature to obtain a reaction solution. The reaction mixture obtained above was poured into 200mL of a 10% aqueous hydrochloric acid solution, extracted 3 times with 40mL of dichloromethane each time, washed with 40mL of water, dried over magnesium sulfate, and the organic layer was concentrated to obtain 18.2g of 3, 3 ', 5, 5 ' -tetrakis (dibromoethyl) -1, 1 ' -diamantane.
Further, 3 ', 5, 5 ' -tetrakis (dibromoethyl) -1, 1 ' -diamantane obtained above was dissolved in 20mL of dimethyl sulfoxide, and 28g (250mmol) of potassium tert-butoxide was added thereto at room temperature, followed by stirring for 48 hours. The reaction mixture was poured into 400mL of water, extracted 3 times with 200mL of dichloromethane each time, washed with 200mL of water, dried over magnesium sulfate, and the organic layer was concentrated to obtain 11.0g of 3, 3 ', 5, 5 ' -tetraacetylenyl-1, 1 ' -diamantane.
(2) Polymerization of 3, 3 ', 5, 5 ' -tetraalkynyl-1, 1 ' -diamantane and production of varnish for copper-doped organic film
5g of 3, 3 ', 5, 5 ' -tetraacetylenyl-1, 1 ' -diamantane obtained in example 1(1) above was dissolved in 45g of 1, 3-dimethoxybenzene, 0.1g of bis (benzonitrile) palladium (II) dichloride was added, and the reaction was carried out under dry nitrogen at 190 ℃ for 6 hours, and the reaction solution was added dropwise to 10-fold volume of methanol, and the precipitate was collected and dried to obtain a prepolymer. The molecular weight of the prepolymer was determined in terms of styrene by Gel Permeation Chromatography (GPC) using TOSOHCORPORATION, and the number average molecular weight (Mn) was 18200. Further, as a result of calculating the remaining rate of unreacted unsaturated bonds in the prepolymer from the absorbance ratio between the IR spectrum of carbon-carbon triple bonds in the preamplified polyamantane compound and the IR spectrum of carbon-carbon triple bonds in the prepolymer, the remaining rate of unreacted unsaturated bonds was 61%. The IR analysis was performed by using FT IR8900 manufactured by SHIMADZU. 3g of the obtained prepolymer was dissolved in 27g of cyclopentanone, filtered through an テプロソ (registered trademark) filter, and copper-doped by a method conventional in the art to obtain a copper-doped varnish for organic films.
(3) Manufacture of capacitive touch screen
An electrode layer was formed on the optical filter, and the above copper-doped organic material varnish was applied on the optical filter and heat-treated at 400 ℃ for 1 hour to form an electrode layer having a thickness of 0.1. mu.m.
Example 2
(1) Synthesis of 3, 3 ', 5, 5' -tetramethyl-7, 7 '-diacetylene-1, 1' -diamantane
The same procedures as in example 1(1) were repeated except for using 72.9g (0.3mol) of 1-bromo-3, 5-dimethyladamantane in place of 64.5g (0.3mol) of 1-bromoadamantane in example 1(1) and changing the bromine amount to 35g (0.22mol) to obtain 58g of a product. The IR analysis revealed that the absorption of the bromine group was 690 to 515cm-1, and the molecular weight was 484 by mass analysis, from which it was found that the obtained product was 3, 3 ', 5, 5' -tetramethyl-7, 7 '-dibromo-1, 1' -diamantane.
In example 1(1), the same procedures as in example 1(1) were repeated except that 50g (103mmol) of the 3, 3 ', 5, 5 ' -tetramethyl-7, 7 ' -dibromo-1, 1 ' -diadamantane obtained above was used instead of 20g (34mmol) of 3, 3 ', 5, 5 ' -tetrabromo-1, 1 ' -diadamantane, the amount of bromine was changed to 27.25mL (387.5mmol) in 18mL (256mol), and the amount of aluminum chloride (III) was changed to 4.55g (33.3mmol) in 3.3 ', 5, 5 ' -tetramethyl-7, 7 ' -diacetylene-1, 1 ' -diadamantane, 31.5g of 3, 3 ', 5, 5 ' -tetramethyl-7, 7 ' -diacetylene-1, 1 ' -diadamantane was obtained.

In examples 1 and 2, a prepolymer was obtained in the same manner as in example 1 and 2 except that 5g of 3, 3 ', 5, 5 ' -tetramethyl-7, 7 ' -diacetylene-1, 1 ' -diamantane obtained in example 2 and 1 was used in place of 5g of 3, 3 ', 5, 5 ' -tetraacetylene-1, 1 ' -diamantane. The number average molecular weight of the prepolymer obtained was 21300. The remaining ratio of unreacted unsaturated bonds was 21%. 3g of the obtained prepolymer was dissolved in 27g of cyclopentanone, and copper doping was performed by filtration through a filter using a conventional method in the art to obtain a copper-doped varnish for organic films.
(3) Manufacture of capacitive touch screen
Using the copper-doped varnish for organic material obtained above, a semiconductor device was obtained by performing the same steps as in example 1 (3).
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
