Abstract

Abstract It was found that the [N,N′-bis(5-alkylsalicylidene)ethylenediaminato Ni(II) (abbreviated as (Cn-Salen)2Ni: n = 6, 12) complexes show two smectic liquid crystalline phases, SE and SA. The SE ⇆ SA phase transition in the C12-salen)2Ni complex is accompanied by a reversible stretching of the interlayer distances. A dimer SE-monomer SA phase transition can be deduced from this phenomenon.
