Studies on Induced Smectic Phases (II) Transition Enthalpies, X‐ray Patterns and Layer Spacings of Orthogonal Phases of Binary Mixtures of Nematogens with Contrasting Dielectric Anisotropies

Abstract

Abstract Binary mixtures of two nematogens, 4,4′‐di‐n‐heptyl‐azobenzene with 4‐n‐pentyl‐4′ ‐cyano biphenyl were studied by optical, calorimetric and X‐ray measurements. At a given concentration induced phases with a sequence S A , S B , S E were detected, the properties of which were discussed.
