Polymorphism of the Mesomorphic Compound Terephthal-<i>bis</i>-Butylaniline (TBBA)

Abstract

On the basis of x-ray monodomain and powder patterns, the structure of new identified terephthal-bis-butylaniline phases is described. These phases present a relatively high degree of order and appear as intermediate states between the smectic mesophases and the crystalline state.
