Synthesis of Highly Ordered Polymers Using Supramolecular Liquid Crystal Phases

Abstract

Novel supramolecular compounds were prepared from dipyridyl compounds and benzoic acid derivatives possessing acrylate moieties. Their properties were investigated by polarized light optical microscopy, DSC, and powder X-ray diffractions. Most of these complexes exhibited smectic A phases at room temperature. After irradiation with a UV light (365nm) for 10 hours, polymerization was confirmed by monitoring with IR spectroscopy. The X-ray diffraction patters of these polymers were similar to those of the monomers, and proved that these polymers kept the arrangements of liquid crystalline monomers.
