Research of novel azobenzene liquid crystal with high birefrience and the phase behavior

摘要

In order to obtain an important azobenzene liquid crystal with high birefrience, click chemistry reaction was used to preparation the compound. In this paper, the novle azobenzene liquid crystal was synthesized by (4-Ethynyl-phenyl)-(4-trifluoromethyl-phenyl)-diazene and C_8H_(17)Br as raw materials. In addition, the synthesized compound was characterized by FT-IR and ~1H-NMR to confirm the consistent structure, and the liquid crystal phase behaviors of phase sequences were investigated by polarizingmicroscope (POM).
