Chiral phenoxypropionates having halogenated 2,5-diphenylpyrimidine cores were synthesized and the effect of a halogeno-substituent on the physical properties such as mesomorphic behavior, spontaneous polarization (Ps) and response time (τ) were investigated.The introduction of a halogen atom to the phenyl ring of 2,5-diphenylpyrimidine core led to a decrease in the thermal stability of mesophases.The Ps values in the achiral host liquid crystal mixture were increased by introducing the halogen atom.However, response times were not improved. - Keywords: ferroelectric liquid crystal, phenoxypropionate, halogeno-substituent
