Embodiment

[0183] Hereinafter, the present invention will be described in detail through examples. These examples are for illustrating the present invention. The present invention is not limited to the following examples, and can be implemented with any modifications within the scope not departing from the gist thereof.

Synthetic example 1

[0184] [Synthesis Example 1: Synthesis of p-vinylbenzenethiol]

[0185] 1.64 g of Mg powder was dispersed in 53 mL of tetrahydrofuran (THF) at room temperature under a nitrogen atmosphere, and 8 mL of 4-bromostyrene (manufactured by Aldrich) was slowly added dropwise. In order to suppress the rise of the heat of reaction during the reaction, it was cooled stepwise to -15°C to prepare a Grignard reaction solution. While maintaining this temperature, sulfur powder (manufactured by Aldrich) was added to the reaction liquid, and the temperature was gradually returned to 0° C. over 3 hours. After 3 hours, 1N NaOH aqueous solution was added to the reaction liquid, followed by stirring. The reaction liquid was filtered off, and liquid separation was carried out with ether. The aqueous layer was collected and concentrated under reduced pressure at room temperature. 1N HCl was slowly added to the aqueous layer, and when the pH was adjusted to 6.5, the aqueous layer was pale yellow. ...

Synthetic example 2

[0190] [Synthesis Example 2: Protection of Thiol by Acetyl Group]

[0191] 2.7 g of p-vinylbenzenethiol obtained in Synthesis Example 1 was dissolved in 300 mL of THF at -5°C under a nitrogen atmosphere, and 10 mL of pyridine was added as a deoxidizer. After stirring well for 1 hour, 3 g of acetyl chloride was slowly added dropwise. After the dropwise addition was completed, the mixture was stirred for 1 hour, and pyridine hydrochloride was precipitated. The pyridine hydrochloride was filtered off, the filtrate was concentrated under reduced pressure at low temperature, and liquid separation and extraction were performed with benzene and water, and the organic layer was concentrated under reduced pressure at low temperature to obtain a light yellow liquid. This liquid was purified by alumina column chromatography (dichloromethane) to obtain p-vinylbenzenemercaptan having an acetyl-protecting group as the target product.

[0192] In addition, the obtained products were measur...

Abstract

For the purpose of providing an insulting layer which enables to improve device characteristics when used in an electronic device, a polymer insulator containing a repeating unit represented by the formula below is contained in the insulating layer. In the formula, R represents a direct bond or an arbitrary linking group; Ar represents an optionally substituted divalent aromatic group; and R represents a hydrogen atom, a fluorine atom or a monovalent organic group.

Description

technical field [0001] The present invention relates to an insulating layer, an electronic component having the insulating layer, a field effect transistor, and polyvinylthiophenol. Specifically, the present invention relates to an insulating layer capable of improving electrical performance, an electronic component and a field effect transistor having the insulating layer. Effect transistors, and polyvinylthiophenol that can be used for the insulating layer. Background technique [0002] As an organic insulating layer expected to be used as a constituent member of an organic thin film transistor or the like, for example, polyimide, benzocyclobutene, photoacryl or the like are used. However, the actual situation is that the organic insulating layer has not yet exhibited device characteristics to the extent that it can replace the inorganic insulating layer (see Patent Document 1). Therefore, in order to realize organic electronic devices such as organic thin film transistor...
