Abstract
The parallel alignment of anisotropic molecules gives rise to the anisotropy of various physical properties, which is the striking feature of the liquid-crystalline state. It will be shown that there is a close relation between the anisotropy of physical properties and the molecular structure, as well as the phase structure. The anisotropy of physical properties is an essential condition for a number of practical applications besides the temperature range and the chemical stability. Therefore, the knowledge of structure-property relations is of growing interest in molecular engineering of liquid crystalline compounds with specific properties.
