Hierarchical discs

Abstract

The hierarchical self-assembly of disc-shaped molecules leads to the formation of discotic liquid crystals. These intriguing materials are of fundamental importance not only as models for the study of energy and charge migration in self-organised systems but also as functional materials for various device applications. This has generated tremendous interest in this field. In this review article, we have summarised our synthetic work on discotic liquid crystals.

Side Chain Liquid Crystalline Polymers: Advances and Applications

“…16.3a), molecules have orientationally ordered arrangement of discs with no long-range translational order. This is the least order (usually high temperature) in the disc-like molecules (Kumar 2009). The nematic mesophase can be assimilated to a lamellar nematic liquid crystal, in which the director vector (an optical axis) is perpendicular to the average direction along which the flat molecules are aligned, as illustrated in Fig.…”
