Electrophysical properties of a system with induced antiferroelectric phase comprising cyano compound

Abstract

The DSC, electrooptic and X-ray results for the system composed of two synclinic compounds CNCH2COO(CH2)6OphPhCOOPhCOOC*H(CH3)C6H13 and C5H11COO(CH2)3OPhCOOPhPhCOOC*H(CH3)C6H13 are presented. The antiferroelectric SmC*A phase induces in this system and it was confirmed by physical measurements. It was found out that the mechanism of SmC*A phase induction is different than in systems comprising compound with perfluoroalkyl chain.
