摘要：

Anew central linkage group aromatic Schiff base liquid crystal has been synthesized by using condensation of an Alkyl chloride (CnH2n+1(Cl)n=4,5,6,7).This crystal was characterized by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). Schiff base liquid crystal sample exhibiting the sematic phase. The temperature variation of the dielectric anisotropy (Delta epsilon) of the sample has been measured. The dielectric anisotropy was found to be (Delta epsilon =0.38). This research studies the effects of concentration of Schiff base liquid crystal on the behavior of optical hunting and threshold power.
