3B13 Combinatorial Synthesis and Property of Liquid Crystals Formed by Achiral Banana-Shaped Molecules

Abstract

Combinatorial methodologies that were developed for the high-speed synthesis and high-throughput screening of pharmaceuticals could help to overcome the time-consuming "one-at-a-time" process of material synthesis and evaluation. This study demonstrates the application of this technique in designing new materials for liquid crystalline molecules, especially achiral banana-shaped molecules. Previously, the banana-shaped molecules have been extensively studied, since they exhibited various kinds of smectic phases that possess unusual properties. Particularly, a presence of chiral and/or helical smectic phases is interesting, since the molecules do not have the asymmetric carbon. In this work, we will present new banana-shaped molecules that possess different alkyl functional chains on both side chains. We also present tentative conclusions about the correlation between structure and property.
