  Asymmetrical Azobenzene Liquid Crystals with High Birefringence Prepared via Click Chemistry

  摘要：

  Asymmetrical azobenzene liquid crystals with high birefringence were prepared via the click chemistry method. The chemical structures of the synthetic intermediates and compounds were confirmed by FT-IR and( 1)H-NMR. The liquid crystal behavior, including transition temperatures and phase sequences, were investigated by DSC and POM. The effect of the alkyl substituents on liquid crystal behavior is discussed in detail. Then, the birefringence values of the liquid crystals were measured using polarizing light interferometry method. Moreover, the characteristics of selective reflection, which was associated with the value of birefringence, were studied.
