Reentrant Nematic and Smectic C Phases in Binary Systems of 4-(?-Cyanethyl)-Phenyl 4-n-Alkyloxy-Cinnamates

Abstract
In binary systems of 4-(β-cyanethyl)-phenyl 4-n- alkyloxycinnamates reentrant nematic and reentrant smectic C phases occur. In three systems studied the phase sequences SC Nre SA N IS and SC(re) Nre SC SA N IS were found.
