摘要
合成了１个新的手性Ｓｃｈｉｆｆ碱类液晶并以ＤＳＣ、偏光显微镜及变温红外光谱等手段对其热致相变过程进行了研究。
A new chiral liquid crystal with Schiff base group has been prepared. The struc ture of liquid crystal was confirmed by elementary analyses and ￣o 1H NMR. 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.
