A series of supramolecular mesogens have been synthesized and assembled using pyridone functionalities. These species will be analyzed to determine the formation and identity if liquid crystalline phases. It is expected that any mesophases formed from these assemblies will have significantly higher clearing temperatures than those observed in those formed through a benzoic acid/pyridine system (single hydrogen bonds). The ability of the pyridone species to self-assemble and competitively form one mesophase or another will also be examined through thermal and optical analysis. These studies will grant insight into the nature of mesophase stability and formation.
