Influence of Confining Geometries on Collective Dynamic Modes in Chiral Smectogens

While confined nematogens have been extensively investigated in adsorbents of a large variety of cavity sizes, comparably little is known about smectogens under geometrical restraints. We study ferroelectric smectogens in porous material from nanometer to micrometer cavity sizes. No influences on th...

Description
Summary:While confined nematogens have been extensively investigated in adsorbents of a large variety of cavity sizes, comparably little is known about smectogens under geometrical restraints. We study ferroelectric smectogens in porous material from nanometer to micrometer cavity sizes. No influences on the molecular dynamics but dramatic changes in the collective reorientation behaviour, in particular a disappearance of the collective modes in nanometer pores and in disordered cellulose membranes is observed.
