Embodiment 1

[0041] (1) Synthesis of 3,3',5,5'-tetraethynyl-1,1'-diadamantane

[0042]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 t...

Embodiment 2

[0051] (1) Synthesis of 3,3',5,5'-tetramethyl-7,7'-diethynyl-1,1'-diamantane

[0052] 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.

[0053] 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 discloses an organic capacitive touch screen which comprises a protective glass layer, a polarizer, upper glass, an electrode layer, an optical filter, a liquid crystal layer, a TFT (thin film field effect transistor) layer and lower glass, wherein the material of the electrode layer is a copper-doped prepolymer containing a cagelike-structure compound.

Description

technical field [0001] The invention relates to a touch screen, in particular to an organic capacitive touch screen. Background technique [0002] At present, capacitive touch screens have become the main components of human-computer interaction in the market, and can provide better user experience effects than traditional resistive touch screens and infrared touch screens. Therefore, it is more and more used in portable consumer electronic products such as mobile phones, MIDs, and tablet computers, and has become an indispensable main component. [0003] The currently used electrode materials, when touched, the capacitance change is not large enough, the touch sensitivity is not high, and a good touch screen function cannot be realized. Contents of the invention [0004] An organic capacitive touch screen comprises a protective glass layer, a polarizing plate, an upper glass, an electrode layer, a light filter, a liquid crystal layer, a thin film field effect transistor ...
