  Liquid-crystalline polymorphism of 4-heptyloxybenzylidene-4′-alkyloxyanilines and their phase equilibrium with 4-octyloxyphenyl 4-nitrobenzoate

  摘要：

  This paper describes the synthesis and liquid-crystalline properties of the homologous series of 4-heptyloxybenzylidene-4'-alkyloxyanilines (7-n). Six of them are presented for the first time. Based on the polarization microscopy (POM and TOA methods) and the calorimetric (DSC) measurements following polymorphism has been detected: nematic, smectic C and smectic I mesophases. The presence of these mesophases was confirmed by the miscibility method, using 4-octyloxyphenyl 4-nitrobenzoate and terephtal-bis (4-butyloaniline) as a mesophase references.Extraordinary results have been found in the mixtures of the investigated compounds with 4-octyloxyphenyl 4-nitrobenzoate; Induced smectic A has been observed, which is connected with very strong intermolecular interactions. Additionally destabilization of nematic and smectic C phases was visible. (C) 2012 Elsevier B.V. All rights reserved.
