| Research Abstract |
In order to construct ionic liquid crystals by supramolecular assembling, the followingmethodologies were developed. Pyridylmethyl imidazoliums were synthesized as key building block forionic liquid crystals via hydrogen bonding (H-bonding) with carboxylic acid as H-bonding donor.Zwitterionic imidazolium-carboxylates were applied to the generation of lithium-ion-containing liquidcrystals by the addition of lithium salts. Crystal structures of zwitterionic imidazolium-carboxylateswere elucidated by single crystal X-ray analysis. A dimer type disc of dicarboxylic acid containing acavity in the center of the disc afforded a columnar liquid crystalline phase with cavities.
