Abstract

The synthesis and mesomorphic properties of new non-symmetrical bent-shaped compounds containing a chiral moiety are reported. These materials were built up from 3-hydroxybenzoic acid as a central unit with a chiral terminal group derived from lactic acid. A columnar phase of the B 1REV type with tilted molecules was observed in a wide temperature range down to room temperature. The ferroelectric-like character of switching with one peak in a half-period of the triangular electric field was observed and supported by texture observations and electro-optical changes. A longer terminal group ending with a double bond makes the compounds ready for polymerisation.
