The main objective is to gain new knowledge on mesomorphic, structural, photochromic, dielectric and electro-optic properties of liquid crystalline (LC) phases with ferro- and antiferroelectric ordering in new materials with the aim to improve understanding of molecular structure - physical property relationship for this class of soft matter materials. Low molar mass LCs, monomeric LC materials and eventually side-chain liquid crystalline polymers and elastomers will be considered for the studies. Work on the PhD. thesis will include the following tasks: (I) sample preparation and alignment; (II) identification and study of mesophases and phase transitions for new LC materials; (III) measurements of the spontaneous polarization, molecular tilt angle, helix pitch length for the ferro- and antiferroelectric phases; (IV) study of dielectric, electro-optic and photochromic properties of new LCs; (V) discussion of the obtained results and established effects with respect to molecular structure of the studied LC materials.
