摘要：

New chiral dopants having a chiral center directly connected to the core aromatic ring were designed and synthesized. Those discussed here are 1-arylethyl alkyl ethers, 2-arylpropanoates, O-acyl and O-alkylcyanohydrins, 2-arylalkanenitriles, aryl alkyl sulfoxides, alpha-aryl-gamma-alkyl-gamma-lactones, and 1-aryl-2-alkyl-1-cyanocyclopropanes. Ferroelectric liquid crystal mixtures doped with one of the compounds exhibited high spontaneous polarization (Ps). The sign of Ps was found to well correlate to the absolute configuration of the chiral center of the dopant.
