Synthesis and characterization of new liquid crystalline compounds derived from novel aromatic ring structures

Abstract

The research on non-covalent interactions has become an important area of research due to their significance in biological functions, drug delivery applications, material properties and the device fabrication. Supramolecular assemblies of complex structure have been found in natural and artificial systems, which arises as a result of multiple non-covalent interactions among small structural motifs and molecular sub-units(1). With this broad area of supramolecular science, research on the properties and applications of liquid crystals have caught increasing attention in the last two decades(2). Liquid crystals (LCs) are functional soft materials which possess both order and mobility(3) ranging from the molecular to macroscopic level(4) . These liquid crystals are classified into thermotropic LCs (temperature dependent) and lyotropic LCs (mesophase is obtained by varying concentration and /or temperature). Based on the shape of the mesogenic molecules, thermotropic LCs are classified into three groups: (a) calamitic (rod-like), (b) bent-core (bad rods, boomerang, banana-like) and (c) discotic (disk-like) LCs
