Abstract: Anew chiral liquid crystal with Schiff base group has been prepared. The struc ture of liquid crystal was confirmed by elementary analyses and 1HNMR. Its phase transi tion was investigated by polarized optical microscope, DSC and temperature-depending FTIR spectra.The results showed that the chiral Schiff base showed monotropic phases behavior in certain temperature range, the phase sequence is I-N-SB-SG-K on the cooling sequence.

Key words: Liquid crystal, Smectic liquid crystal, Chiral liquid crystal, Nematic liquid crystal
