Abstract
A kind of chiral azobenzene was synthesized. The formation of chiral azobenzene was confirmed by IR and1H NMR spectroscopy, and mesomorphic properties were investigated by DSC and POM. The reversible optically induced switching effect betweentransandcisisomer 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.
