Sažetak
A liquid crystal (LC) is a state of matter that occurs between solid and liquid. The molecular shape influences the packing of molecules and also determines the longer-range attractive and repulsive forces responsible for the stability of liquid-crystalline phases. Changing the structures of the mesogenic units and the terminal groups attached to them, varying the length of the spacer and the links between it and the mesogenic units enables investigation of structure-property relations. [1] The chirality of molecules in LC has a remarkable influence on the macroscopic physical properties of these systems, including the appearance of new phases. Our study has been focused on the synthesis of LC molecules with chiral aryl-3-hydroxy propanoate mesogenic core and its influence on the formation of mesophases (Fig. 1). The utilisation of different aromatic groups changes the electron distribution within the mesogenic core. The incorporation of the naphthyl group broadens the molecule, while a biphenyl group extends its length and polarizability of the mesogenic core promoting interactions between identical mesogenic units. [2] Synthetic pathway and a comparison of the mesomorphic properties of aryl-3-hydroxy propanoate compounds will be discussed.
