Anti-ferroelectric liquid crystal compound

摘要

A novel anti-ferroelectric liquid crystal compounds of the formula (1), wherein R is a linear alkyl group having 6 to 12 carbon atoms, X is a hydrogen atom or a fluorine atom, m is an integer of 1 to 3, n is an integer of 1 or 2, and C* is an asymmetric carbon atom. The above anti-ferroelectric liquid crystal compounds have an anti-ferroelectric phase in a broad temperature range, so that they can be advantageously used as a main component for a liquid crystal material for practical use or as a component for a liquid crystal composition.
