To continue the search for novel series of ferroelectric liquid crystals, an additional two series of compounds, CS(+)-4-[(2-methylbutyl)phenyl]4′-trans-n-alkylcyclohexyl) benzoates and DS(+)-4-[(4-methylhexanoyl)phenyl]4′(4″-trans-n-alkylcyclohexyl) benzoates, where alkyl = C5-C6are reported in this paper. Their mesomorphic properties have been characterized by optical textural observations and DSC. Some of these compounds show a C-S*C-SA-N*-I phase transition sequence. The effects of the alkyl chains on transition temperatures and optically active terminal groups on phase behaviour are discussed.
