Recently columnar liquid crystals have been studied due to their possible application to organic conducting materials. Supramolecular columnar liquid crystals consist of mesogenic unit which can aggregate into discs that will make up the columns which associate to form a two-dimensional network. In this study, we prepared supramolecular columnar liquid crystals containing hydrogen bonding between hydorxyl and pyridyl moieties. Thermal and structural properties of prepared complexes were investigated, and it exhibited hexagonal columnar structure at room temperature.
