Photochemical transformations of 2-arylidene-menthanones- chiral dopants for liquid crystalline systems

摘要

Photochemical E-Z isomerization reaction in the series of chiral 1R,4R-2-arylidene-p-menthanone derivatives has been studied and the behavior of starting materials and photoproducts in liquid crystalline systems was characterized. The differences in photochemical properties of the studied compounds with several benzene rings in arylidene fragments and those containing ester linking groups were revealed and discussed.
