The Properties of Liquid Crystal Materials Incorporating the -CH2O- Inter-ring Linkage

To establish more securely the influence of the -CH2O- inter-ring linkage upon the properties of mesogens of both high and low dielectric anisotropy, a range of ethers with the following general structure has been prepared and their properties examined. The thermal and electro-optic properties of the compounds are discussed, and comparisons made where possible with analogous materials incorporating the -CH2CH2- linkage.
