Sažetak
Inspired by the current research in the field of achiral banana-shaped molecules with ferroelectric properties, four series of dimeric molecules with alkylene spacer I-IV were prepared. The aim of this work was to study the odd-even effect of the spacer and the influence of the chain length on the liquid-crystalline properties of prepared compounds. According to the texture all the compounds display mesogenic properties. Generally, compounds with even number of carbon atoms in the spacer behave like rods while compounds with odd number show the properties characteristic of bent-shaped molecules. Their mesogenic behaviour in relation to odd-even number of carbon atoms in the spacer and different chain length will be discussed.
