(57) [Abstract] [Purpose] A novel liquid crystal compound having ferroelectricity, either alone or mixed with another liquid crystal compound, a method for producing the same, An optical switching element that uses this. [Structure] General formula (1) R-S-A-COO (A) m -OCO-CFH-Q (1) (R: an alkyl group having 1 to 18 carbon atoms, A: a phenylene group, m; 1 Or 2, Q: an alkyl group having 1 or more carbon atoms.) [Effect] The compound as a whole may be used as a dopant liquid crystal in which a ferroelectric phase is induced by adding a small amount of the compound of the general formula (1) or the base liquid crystal. Very good. |
