A new series of chiral homologous thiobenzoates with aliphatic end chains ranging from heptyloxy to dodecyloxy has been synthesized. It has been characterized by optical microscopy, DSC, pitch measurements and electro-optical study. The typical phase sequence of this series on heating is SmC*, N*, BPI, BPH and I phases. The interesting feature of these compounds is to exhibit the SmC*-N* phase transition; moreover the tilt angle in the ferroelectric smectic phase is. very large (similar to 45 degrees) and quasi-temperature independent.
