Abstract

The nematic liquid crystals (LCs) can be converted into cholesteric LCs by different chiral dopants. For the first time the dynamics of a cholesteric phase induction was investigated on dissolution of the single steroid crystal (vitamin D isomers and relative compounds) at the nematic droplet and the new effect of the crystal rotation has been discovered. In all cases the correlation between the rotation direction and screw sense of the cholesteric helix was found. A theoretical model and interpretation of the rotation effect has been proposed.
