Document Type and Number:
WIPO Patent Application WO/2023/074408
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a novel thiophene compound; a method for synthesizing said thiophene compound; and a composition containing said thiophene compound. This composition can be used in coating materials, inks, adhesives, pressure-sensitive adhesives, gas barrier films, color filters, optical films, optical lenses, touch panels, and the like. The present invention relates to a thiophene compound represented by chemical formula (I) or chemical formula (II). (I) (In the formula, R1, R2 and R3 may be the same as, or different from, each other, and each denote a hydrogen atom, -OR4, -SR4, -C(=O)-R4, a phenyl group, a 2-thienyl group or a 3-thienyl group, and R2 may bond to R1 or R3 to form a sulfur atom-containing ring together with the two thiophene ring-forming carbon atoms to which R2 and R1 or R3 are bonded. R4 moieties may be the same as, or different from, each other, and each denote an alkyl group having 1-5 carbon atoms. Y1 denotes a single bond or an alkylene group having 1-10 carbon atoms.) (II) (In the formula, R5, R6 and R7 may be the same as, or different from, each other, and each denote a hydrogen atom, -OR4, -SR4, -C(=O)-R4, a phenyl group, a 2-thienyl group or a 3-thienyl group, and R5 may bond to R6 to form a sulfur atom-containing ring together with the two thiophene ring-forming carbon atoms to which R5 and R6 are bonded. R4 moieties may be the same as, or different from, each other, and each denote an alkyl group having 1-5 carbon atoms. Y1 denotes a single bond or an alkylene group having 1-10 carbon atoms.)
