Five different chiral p-substituted anilines derived from 4-aminobenzoic acid and from 4-aminophenol were condensed with four carbocyclic and heterocyclic aldehydes in order to obtain chiral Schiff bases resembling DOBAMBC and HOBACPC.With the exception of the pyridine-3-carboxaldehyde derivatives, the compounds are mesomorphic.Some of the compounds exhibit ferroelectric SC* phases, and all exhibit SA or Ch mesophases on heating.Benzaldehyde and pyridine-2-carboxaldehyde derivatives show similar mesomorphic behavior, as was to be expected from MNDO semiempirical calculations.Values of the spontaneous polarization of certain compounds were measured.
