Chiral Induction of Micellar Cholesterics From Lamellar Phases

Abstract

It is shown for the first time that induced micellar cholesterics can be obtained from lamellar phases within the sequence: lamellar --> micellar nematic --> micellar cholesteric --> biphasic region --> isotropic phase. The pitch is shortened by over 50 per cent when the temperature is raised within the cholesteric range of about 15 K.
