Abstract
Abstract Three types of chiral dimers, (R)-3-methyladipic acid bis[4-(5-alkyl-2-pyrimidinyl)phenyl] esters, (R)-3-methyladipic acid bis[4-(4-octylphenylcarbonyloxy)phenyl] ester and (R)-3-methyladipic acid bis(4-octyloxyphenyl) ester, were prepared and helical macrostructures induced in cholesteric (Ch) and chiral smectic C (SmC) phases by these chiral dimers investigated and compared to those created by an analogous chiral monomer. The effect of the core structures for chiral dimers and SmC hosts on the generation of helical macrostructures were also investigated. Matching of the core structures between chiral dimers and SmC hosts was found to have significant effect on the emerge of strong helical macrostructures in the SmC phases.
