Mesomorphic properties of lactic acid derivatives and their racemic mixtures in comparison with analogous non-chiral compounds.
Original language description
Abstract We have synthesized series of lactic acid derivatives and studied their mesomorphic properties. Selected homologues consist from a molecular core laterally substituted by a chlorine atom, and we modified both terminal chains. We concentrated on the effect of the terminal alkyl length in the chiral part. For selected homologues both enantiomers were prepared and mixed in racemic mixtures. For all compounds we studied mesomorphic behavior and for one homologue a re-entrance of the SmA phase below the tilted SmC phase was detected, for both chiral enantiomers as well as for the racemic mixture. For chiral compounds with the SmC* phase ferroelectric properties were studied by dielectric spectroscopy and switching properties were described. Re-entrance of the SmA phase was experimentally proved by several experimental techniques including x-ray measurements.
