Observation of a helicoidal smectic A (SmA*) phase in polymorphic liquid-crystal systems with an induced spiral structure

The induction of a helicoidal smectic A (SmA*) phase in binary polymorphic systems including the achiral mesogen p-(n-hexyl) oxyphenyl ether p-(n-octyl) oxybenzoic acid and the chiral smectogen A N-[4-(n-nonylphenyl)benzoyloxy] benzylidene-S-1-benzylethylamine is demonstrated. Induction of SmA*- and N*-phases is observed at small (∼ 1 mole %) concentrations of the chiral component along with an increase in the SmC* → SmA* phase-transition temperature compared to that of the SmC → N transition of the starting achiral mesogen and a decrease in the angle of inclination of the molecules in the SmC* layers
