Paper Abstract

For the relation between the sign and size of the helical twisting power (HTP) and the absolute configuration of a chiral molecule, a couple of different effects are responsible which contribute with different weighting factors to the induction of the pitch of a cholesteric phase. With the concept of decomposition of the chiral induction in an intramolecular and intermolecular chirality transfer two of these effects, the independent contribution of chiral groups within the dopant - far away form each other - to the HTP and the dependence of the HTP on the orientation of the orientation axis with respect to the molecular skeleton of the dopant have been analyzed.
