eng	New Ferroelectric Liquid Crystalline Materials with an Azo Group in the Molecular Core	Six series of new liquid crystalline materials with an azo group located in different parts of the mesogenic core of the molecule have been synthetized and their physical properties studied.The chiral segments of these materials are based on alkoxypropionate or alkyllactate units. For the compounds which show the ferroelectric SmC* phase, the temperature of the spontaneous polarization, the spontaneous tilt angle, the helix pitch and the complex permitivity has been studied. The effect of shifting the azo group in the molecular core and lateral substitution in the core on the pysical properties are discussed.	ferroelectric;liquid crystals;smectic;synthesis;physical properties
