DITHIA-s-INDACENE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a new liquid crystalline compound having more improved physical properties. SOLUTION: A 1,5-dithia-s-indacene derivative or a 1,7-dithia-s-indacene derivative is represented by general formula (1) (wherein, R1and R2denote each independently a hydrogen atom, an alkyl group or an alkoxy group; R3to R12denote each independently a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom or a cyano group; either one of X1and X2is a sulfur atom and the other is a carbon atom; either one of X3and X4is a sulfur atom and the other is a carbon atom; R13, R14, R15and R16are present only when X1, X2, X3and X4are the carbon atoms and denote each a hydrogen atom, an alkyl group or a halogen atom; and dotted lines denote each a double bond when X1, X2, X3and X4to which the dotted lines are bound are carbon atoms and denote each a single bond when the X1, X2, X3and X4to which the dotted lines are bound are sulfur atoms).
