Abstract
Physical macroscopic properties such as the spontaneous polarization Ps, the tilt angle θ, dielectric permittivity ε⊤ as a function of temperature were measured for system with induced SmCA* composed simultaneously of three ring chiral esters with partially fluorinated terminal chain and nonfluorinated. Dielectric and spontaneous polarization measurements on heating and cooling runs show a thermal hysteresis for the phase transition between SmC* and SmCA* phases.
