Abstract

Helical twisting power and temperature dependence of the induced helical pitch have been determined for some representatives of mono- and bis-arylidene derivatives of 3R-methylcyclohexanone in nematic 4-pentyl-4'-cyanobiphenyl. Obtained data were analyzed in comparison with respective values for p-menthan-3-one derivatives studied earlier and also for some arylidene derivatives of various isomeric methylcyclohexanones. Regularities observed were shown to associate with peculiarities of spatial structures of the chiral compounds studied. A significance of hard connection of the central chirality and spiral chirality of the stereospecific twisted arylidene grouping is proved.
