| Popis: |
Seven two ring chiral benzoates with different terminal substituents being isotropic liquids or low temperature monotropic compounds were tested as dopants inducing ferroelectricity in non-chiral Sc mixtures composed from esters. It was found that some of them strongly enhance the stability of smectic C in four component ester mixture up to the concentration of 30 wt.%. The spontaneous polarization Ps, the tilt angle θ, and both parts of complex dielectric permitivity of the doped mixtures upon dopant concentration and temperature were investigated. |
