The Smectic Dimorphism of Hexadecyloxy- and Octadecyloxyazoxy-benzene

Abstract

Abstract 4,4′-di-n-hexadecyloxy- and octadecyloxyazoxybenzene have been investigated by means of a differential scanning calorimeter and the latter also by density measurement. Both substances exhibit smectic B and C modifications, which have been proved by miscibility investigation. Under favourable circumstances both types of modifications may exhibit schlieren textures.
