A synthetic pathway is described for the preparation of the homologous series of (R)-(2-chloropropyl)-4-benzoates with high optical purity.The liquid crystalline members of the series exhibit smectic A phase and can be used as chiral dopants in ferroelectric mixtures.The n=8 member was used in a mixture exhibiting monotropic and the n=9 member enantiotropic smectic C* phase around room temperature.

Applicability of ferroelectric liquid crystals to large screens handling high density information has been demonstrated.High speed and bistable effect are the greater advantages of these materials.The chemical problems to be solved were to synthesize broad-band room temperature substances with high polarisation, negative dielectric anisotropy, large pith and adequate tilt angle.A number of compounds having in their structure the R-(-) 2 chloro propyl group have been synthesized. The smectic stability for these series has been examined.Some compounds exhibit the chiral smectic C phase.All of them can be used as chiral dopants in broad-band room temperatures mixtures.Some examples of these mixtures will be presented.Keywords: liquid crystal, ferroelectric, smectic C, display, material, chiral
