OPTICALLY ACTIVE COMPOUND AND LIQUID CRYSTAL COMPOSITION CONTAINING THE COMPOUND

摘要

An optically active compound of the general formula (1) useful as a chiral dopant, and use thereof for a liquid crystal composition, the above optically active compound having a remarkably large helical twisting power (HTP) of as large as 50 or more and having a property that the helical pitch induced decreases in length with an increase in temperature, so that the optically active compound has an excellent value as a chiral dopant for a nematic liquid crystal.
