The Preparation and Thermodynamic Properties of Some Chiral 4-Alkyl-4′-Cyanostilbenes and Tolans

  • Chapter

Abstract

It is well established that optically active nematogens exhibit cholesteric mesophases. The term “chiral nematic” was coined by Dolphin1 to describe this general class of liquid crystals. Examples of chiral nematic liquid crystals have been synthesized based on Schiff bases1,2 aromatic esters,3 cinnamic esters4 and biphenyls.5 We have recently prepared two new series of liquid crystals with the trans stilbene and tolan structures6,7 and have now obtained the optically active analogs in these series. This paper will describe the compound preparation and list the thermodynamic properties that were obtained.
