Synthesis and Ferroelectric Properties of a Homologous Series of Chiral Esters of 2,5-DiphenylpyrimidinesA new homologous series of (S)-2-(4-n-alkyloxyphenyl)-5-{4-(2-chloro-3-methylpropanoyloxy)-phenyl}-pyrimidines has been synthesized. Polymorphy, phase transition temperatures and transition enthalpies as well as the ferroelectric properties of these compounds are presented. Especially, the influence of the length of the non chiral side chain on the tilt angle (measured by x-ray) and the spontaneous polarization in the SmC* phase as well as in a novel smectic phase type (SmM*) which has been discovered in these compounds will be discussed.
