New Chiral Ether Derivatives of 2-Arylidene-p-Menthane-3-Ones as Components of Induced Ferroelectric Systems

Abstract

New 2-arylidene-p-menthane-3-ones containing the ether bridging group in the arylidene fragment have been synthesized and studied as chiral dopants in ferroelectric liquid crystal mixtures. The ferroelectric properties of these compositions were compared with those for compositions including chiral dopants that do not contain any bridging group. The influence of bridging group and terminal alkyl substituent length in the dopant molecule on the ferroelectric parameters of systems studied is discussed.

Key Words:

• induced ferroelectricity
• chiral dopants
