Abstract

We find that certain cyano Schiff bases and cyanobiphenyls with alkyl or alkoxy end groups exhibiting a bilayer smectic-$A$ phase, also exhibit a reentrant nematic phase at high pressure. A tentative model of the bilayer smectic-$A$ phase and the mechanism whereby the reentrant transition may occur is presented.
