  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.

  A series of four novel azobenzene liquid crystals (LCs) with high birefringence were synthesized by coupling of intermediate molecules with a phenylacetylene fragment. The chemical structures of synthetic intermediates and compounds were confirmed by FT-IR and H-1-NMR. The LC behavior including transition temperatures and phase sequences were investigated by differential scanning calorimetry (DSC) and polarizing optical microscope (POM). As a very important parameter, the birefringence was also measured using polarizing light interferometry method. Moreover, the characteristics of selective reflection which was associated with the birefringence of the N*-LC dropped with azobenzene LCs and the effect of trans-cis photoisomerization of these compounds on selective reflection were studied in detail.
