In the design of functional organic materials, it is important to use molecular interactions. Hydrogen bonding is one of the key interactions for molecular association and recognition in nature. Recently, new types of hydrogen-bonded liquid-crystalline (LC) complexes have been obtained by molecular recognition between complementary components. For example, molecular recognition by hydrogen bonds between carboxylic acid and pyridyl moieties results in the quantitative formation of well-defined structures of mesogens. In the hydrogen-bonded liquid crystals, dynamic nature of hydrogen bonding gives unique LC structures of complexes such as polymer networks, polymer alloys, and one-dimensional polymers. For LC polymer networks, stable liquid-crystalline phases have been induced by the formation of dynamic intermolecular mesogen consisting of polymer side chain and a small molecule. A wide variety of supramolecular mesogenic materials can be obtained by the molecular aggregation via various hydrogen bonds.
