Optical Activity in the Isotropic and Blue Phases of a Chiral Liquid Crystal

Abstract

Some liquid crystals exhibit mesophases between the isotropic phase and the chiral nematic (or cholesteric) phase. There may be up to three different spatial structures in a temperature interval as small as 1 K. These phases are optically not birefringent and they reflect preferentially short wavelengths: that is why they are called blue phases1.KeywordsLiquid CrystalOptical RotationOptical ActivityIsotropic PhaseCholesteric Liquid CrystalThese keywords were added by machine and not by the authors.
