Abstract
Two series of new chiral liquid crystalline substances have been synthesized with a lactate chiral group. All compounds exhibit the blue phase, the cholesteric phase and the SmA phase. The ferroelectric SmC* phase was observed for the substance with two chiral centers (n=10) only. The soft mode was detected in the whole range of the SmA phase for all substances and temperature dependences of its relaxation frequency and dielectric strength were determined.
