Abstract

Alkanediacids 4-(4'-Cyano)-biphenyl Diesters, Twin M esogens Four twin mesogens from the hom ologous series of alkanediacids 4-(4'-cyano)-biphenyl diesters (n = 4, 6, 8, 10) have been synthesized and their thermal properties have been studied. Assignment of the phases has been made by means o f polarizing microscopy and DSC measurements. It has been found, that the increase of the spacer length causes the lowering of the mesophase temperature range and influences other thermodynamic parame­ ters of the compounds investigated.

Keywords: Alkanediacids 4-(4′-Cyano)-biphenyl Diesters; Twin Mesogens
