New biphenyl and phenylpyrimidine type ferroelectric liquid crystals were synthesized and their physical properties studied. Each of these compounds has a chiral carbon atom directly linked to the core structure or has a methylene chain between the chiral carbon atom and the core moiety. The internal methylene chain and the core structure have an effect on the temperature range of the phase transition and the rotational viscosity in the Sc* phase, respectively.
