Generation of Ionic Liquid Crystals by Supramolecular Assembly

为了通过超分子组装来构建离子液晶，发展了以下方法。以羧酸为氢键给体，通过氢键作用合成了吡啶甲基咪唑盐作为离子液晶的关键结构单元，并将其应用于锂盐的加成制备含锂离子液晶.用单晶X-射线衍射分析确定了两性离子咪唑羧酸盐的晶体结构。二羧酸的二聚物型盘在盘的中心含有空腔，提供了具有空腔的柱状液晶相。

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.
