Synthesis and mesophase characterisation of a series of new triazine-based disc-shaped molecules

Abstract

A series of symmetrical disc-shaped materials with a heteroaromatic 1,3,5-s-triazine core and nine alkoxy chains at the peripheral position has been designed and synthesised in a simplified way. All the compounds show hexagonal columnar mesophase. The mesomorphic properties of the compounds have been characterised with the help of polarising optical microscopy (POM), differential scanning calorimetry (DSC) and temperature controlled low angle XRD-experiments.
