A Lyotropic Chiral Smectic C Liquid Crystal with Polar Electrooptic Switching

A Lyotropic Chiral Smectic C Liquid Crystal with Polar Electrooptic Switching

A lyotropic analogue of the ferroelectric smectic C* phase has been found. The lyotropic smectic C* phase shows macroscopic chirality effects, such as a helical ground state and polarity‐dependent electrooptic switching, thus indicating the presence of a spontaneous electric polarization. The helici...

Zusammenfassung:A lyotropic analogue of the ferroelectric smectic C* phase has been found. The lyotropic smectic C* phase shows macroscopic chirality effects, such as a helical ground state and polarity‐dependent electrooptic switching, thus indicating the presence of a spontaneous electric polarization. The helicity implies communication of the chiral director twist across the achiral solvent layers separating adjacent layers of the chiral mesogens.
