Abstract

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-S_B-S_G-K on the cooling sequence.

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