Enhancement of the cholesteric induction power by macrocyclization in liquid crystal dimers with a chiral spacer

Abstract

A liquid crystal dimer with a chiral spacer increases the helical twisting power in a nematic liquid crystal solvent by a factor of four because the two tails are connected. In the macrocyclized dimer, the two mesogens are fixed in a skewed overlapping alignment with the handedness determined by the spacer’s chirality.
