Synthesis of Chiral Azobenzene and their Effect on Cholesteric Liquid Crystal

Article Preview

Abstract:

A kind of chiral azobenzene was synthesized. The formation of chiral azobenzene was confirmed by IR and 1H 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.
