摘要：
A kind of chiral azobenzene was synthesized. The formation of chiral azobenzene was confirmed by IR. and H-1 NMR spectroscopy, and mesomorphic properties were investigated by DSC and POM. The reversible optically induced switching effect between trans and cis isomer of chiral azobenzene was demonstrated by a UV/Vis/NIR spectrophotometer. It was found that cholesteric liquid crystal molecular alignment could be adjusted by these chiral azobenzene.
