Thermodynamic studies of induced antiferroelectric phases in chiral and racemic systems

Abstract

Bi- and multicomponent mixtures consisted of two groups of synclinic chiral esters: first one with a partially fluorinated terminal chain and the second one with hydrogenated terminal chain have been used for investigations. For some systems the induction of the anticlinic smectic CA* phase was observed. Enthalpies of the phase transitions for the systems with induced smectic CA phase upon compositions and specific heat were measured by DSC method.
