Effect of Chiral Dopants Molecular Structure on Temperature Dependencies of Induced Cholesteric Helical Pitch

摘要

Effect of the chiral dopants molecular structure onthe kind of the temperature dependencies of the inducedcholesteric helical pitch has been studied for LC systems on thebase of 4-pentyl-4'-cyanobiphenyl or 4-methoxybenzylidene-4-butylaniline including chiral S, #alpha#-phenylethylamine and E-1R, 4R-2-(4-phenylbenzylidene)-p-menthance-3-one derivatives.The established correlations and their possible reasons have been discussed.
