A new series of liquid-crystalline compounds with an intramolecular hydrogen bond were synthesized by the reaction of 4-ethoxysalicylaldehyde with 4-alkyl- and 4-alkoxyanilines.Substitution of the alkyl radical in the N-phenyl ring by an alkoxyl radical with the same overall chain length leads to an increase in the phase transition temperatures.However, the general temperature range of the meso phase is not reduced here.A large number of smectic phases are observed in the alkoxy derivatives.A smectic C phase appears in addition to the smectic A phase.
