Characterisation and Mesomorphic Behavior of Rod-Shaped Unsymmetrical Imine with a Fluorinated Chain and a Carboxylic Group

Abstract

The synthesis and thermal properties of unsymmetrical imine with a fluorinated chain and a carboxylic group are described. The mesomorphic behavior was investigated via differential scanning calorimetry (DSC) and polarizing optical microscopy (POM) studies. Additionally, we compared the mesomorphic behavior of the azomethine presented in this work with other azomethines.
