Abstract
Two series of new chiral liquid crystalline substances have been synthesize d with a lactate chiral group. All compounds exhibit the blue phase, the ch olesteric phase and the SmA phase, The ferroelectric SmC* phase was observe d 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 tempera ture dependences of its relaxation frequency and dielectric strength were d etermined.
