Dithia-s-indacene derivative

摘要

A 1,5-dithia-s-indacene or 1,7-dithia-s-indacene derivative represented by general formula (1): wherein R¹ and R² each independently represents a hydrogen atom, an alkyl group or an alkoxy group; R³-R¹² each independently represents a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom or a cyano group; either of X¹ and X² represents a sulfur atom while the other represents a carbon atom; either of X³ and X⁴ represents a sulfur atom while the other represents a carbon atom; R¹³, R¹⁴, R¹⁵ or R¹⁶ is present only in the case where X¹, X², X³ or X⁴, respectively, is a carbon atom, and R¹³, R¹⁴, R¹⁵ or R¹⁶ each independently represents a hydrogen atom, an alkyl group or a halogen atom; and a broken line independently indicates a double bond in the case where X¹, X², X³ or X⁴ to which the broken line is connected represents a carbon atom or a broken line independently indicates a single bond in case X¹, X², X³ or X⁴ to which the broken line is connected represents a sulfur atom. A liquid crystal composition comprising the 1,5-dithia-s-indacene or 1,7-dithia-s-indacene derivative represented by the general formula (1). An electronic device comprising the liquid crystal composition.
