PA16 Supramolecular liquid crystals generated by assembling of stilbene derivatives possessing carboxy groups

Abstract

Supramolecularly assembled discotic liquid crystals were prepared from isophtahlic acid derivatives substituted with 3,4,5-tridodecyloxystyryl group via intermolecular hydrogen bonding between carboxys. The compounds exhibited columnar liquid crystal phases. Structural characterization of superstructures was performed by polarized light optical microscopy (POM), differential scanning calorimetry (DSC), and X-ray diffraction (XRD) experiments.
