Smectic Polymorphism and Molecular Shape-the Orthogonal Phases

Abstract

A method has been developed that can be used to describe the volume of space occupied by a given molecule with a known conformational structure as it rotates about a defined axis. The packing requirements of these volumes of revolution have been utilized in the prediction of phase formation, particularly of the B and E phases. Conculusions indicate that the subtle balance balance between steric and dipolar properties of a mesogen determine the pahse types ultimetely exhibited by the material.
