A series of new optically active cyclic ethers such as tetrahydrofurans, chromans and dihydrobenzofurans were synthesized, and their physical properties as a chiral dopant for FLC were investigated. Correlation between the the chemical structures and the physical properties, especially spontaneous polarization (Ps), are discussed and compared with that of the corresponding lactones.
