Preparation and Magnetic Properties of All-Organic Chiral Liquid Crystal

Abstract

We have established the synthetic method for all-organic chiral liquid crystalline materials which contain a chiral five-membered cyclic nitroxide unit within the rigid core and can show various calamitic mesophases. Here I report the preparation of racemic and enantiomerically enriched liquid crystalline matereials, which can show a nematic, chiral nematic, smectic C, or chiral smectic C phase over a wide temperature range, and their optical and magnetic properties.
