Embodiment 1

[0042] (1) Synthesis of 3,3',5,5'-tetraethynyl-1,1'-diamantane

[0043]14 g (0.6 mol) of metallic sodium and 600 mL of n-octane were added to a 1000 mL four-necked flask equipped with a thermometer, a stirrer, and a reflux tube, and the inner temperature was cooled to 0°C. While vigorously stirring, a solution obtained by dissolving 64.5 g (0.3 mol) of 1-bromoadamantane in 300 mL of n-octane was slowly added dropwise. Drop into the medium, and keep the internal temperature at 0°C to 5°C. After the dropwise addition, if the temperature did not rise any more, the reaction was continued for 1 hour. Then, about 1500 mL of cold water was injected, and the crude product was filtered, washed with pure water, and dried. Furthermore, the crude product was recrystallized with hot hexane. The resulting recrystallized product was dried under reduced pressure to obtain 32.6 g of a product. IR analysis revealed that the absorption of the Br group (near 690-515 cm-1) disappeared, and the...

Embodiment 2

[0052] (1) Synthesis of 3,3',5,5'-tetramethyl-7,7'-diethynyl-1,1'-diamantane

[0053] In embodiment 1 (1), replace 1-bromoadamantane 64.5g (0.3mol) with 1-bromo-3,5-dimethyladamantane 72.9g (0.3mol), the amount of bromine is changed to 35g ( Except for 0.22 mol), everything else was carried out in the same manner as in Example 1 (1), to obtain 58 g of a product. According to IR analysis, the absorption of the bromine group was found to be 690-515 cm-1, and the molecular weight obtained by mass analysis was 484. From this result, it can be known that the obtained product is 3,3',5,5'-tetramethyl-7,7' -Dibromo-1,1'-diamantane.

[0054] In Example 1(1), 50 g (103 mmol) of 3,3', 5,5'-tetramethyl-7,7'-dibromo-1,1'-diamantane obtained above was used to replace 3 , 3′,5,5′-tetrabromo-1,1′-diamantane 20g (34mmol), change bromine amount 18mL (256mol) to 27.25mL (387.5mmol), and aluminum chloride (III) 3.0g (22mmol) was changed to 4.55g (33.3mmol), and all others were carried out in ...

Abstract

The invention provides a method for manufacturing an organic capacitive touch screen. The method includes the steps of forming a thin-film transistor (TFT) layer on lower glass, forming a liquid crystal layer on the thin-film transistor (TFT) layer, forming an optical filter on the liquid crystal layer, forming an electrode layer on the optical filter, forming upper glass on the electrode layer and forming a polarizer and a protective glass layer on the upper glass. The material of the electrode layer is a copper-doped prepolymer containing a cage structure compound.

Description

technical field [0001] The present invention relates to a touch screen, in particular to an organic capacitive touch screen. Background technique [0002] At present, capacitive touch screen has become the main component of human-computer interaction in the market, which can provide better user experience than traditional resistive screen and infrared touch screen. Therefore, it is increasingly used in portable consumer electronic products such as mobile phones, MIDs, and tablet computers, and has become an indispensable main component. [0003] The electrode materials currently used, when touched, have insufficient capacitance change, low touch sensitivity, and cannot achieve a good touch screen function. SUMMARY OF THE INVENTION [0004] A manufacturing method of an organic capacitive touch screen, comprising: [0005] A thin film field effect transistor (TFT) layer is formed on the lower glass, a liquid crystal layer is formed on the thin film field effect transistor ...
