Abstract

The purpose of this study is to synthesize the ester system ferroelectric liquid crystals 4-(4-(2- methylbutyloxy carbonyl)phenyl)-4'-alkoxy-biphenyl-4-carboxylates (MBPABC_n). In addition to the basic physical of single liquid crystal, such as tilt angle, pitch length, birefringence ((Delta) n), spontaneous polarization (Ps), response time and electro-optics properties, etc., and the physical properties of liquid crystal mixture are studied. The FLC mixture of MBPABC₈ and 4-(4-(2-methylbutyloxy carbonyl)phenyl)4'alkoxy benzoate (MOCPAB₈) present smectic C* phase with wide temperature range. In addition, the tilt angle and spontaneous polarization increased as increasing the MBPABC composition. The results indicate that further consideration for device applications can be made.
