Thermotropic Liquid Crystals from Planar Chiral Compounds: Optically Active Mesogenic [2.2]Paracyclophane Derivatives

The way in which chirality is introduced in a mesogenic molecule is important for determining the properties of the resultant liquid‐crystalline material. The thermotropic liquid‐crystalline compounds (see figure) based on planar, chiral [2.2]paracyclophane (PC) exhibit stable mesophases over a wide...

Description
Summary:The way in which chirality is introduced in a mesogenic molecule is important for determining the properties of the resultant liquid‐crystalline material. The thermotropic liquid‐crystalline compounds (see figure) based on planar, chiral [2.2]paracyclophane (PC) exhibit stable mesophases over a wide temperature range, while the mesophase type could be tuned by altering the nature of the substituents in the PC unit. The planar chiral PC derivatives also reveal a sufficiently high twisting ability in a nematic host.
