The DSC, electrooptic and X-ray results for the system composed of two synclinic compounds CNCH₂COO(CH₂)₆OPhPhCOOPhCOO*H(CH3)C₆H₁₃ and C₅H₁₁COO(CH₂)₃OPhCOOPhPhCOO*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 SnC*A phase induction is different than in systems comprising compound with perfluoroalkyl chain.
