In liquid crystals (LCs), molecules are confined in peculiar environments, where ordered alignment and certain mobility are realized at the same time. Considering these characteristics, the idea of "controlling molecular events within LC media" seems reasonable. As a suitable system for investigating this challenge, we have recently developed a new class of ionic LCs; the salts of amphiphilic carboxylic acids with 2-amino alcohols, or those of carboxylic acids with amphiphilic 2-amino alcohols, have a strong tendency to exhibit thermotropic LC phases. Because of the noncovalent nature of the interaction between molecules, one of the two components can easily be exchanged with, or transformed into, another molecule, without distorting the original LC architecture. In addition, both components are common organic molecules, and a variety of compounds are easily available. Taking advantage of these characteristics, we have succeeded in applying two‑component LCs as chiral media for molecular recognition and reactions. This review presents an overview of our recent studies, together with notable reports related to this field.
在液晶（LCs）中，分子被限制在特殊的环境中，在这种环境中，有序排列和一定的流动性能够同时实现。考虑到这些特性，“在液晶介质中控制分子事件”这一想法似乎是合理的。作为研究这一挑战的合适体系，我们最近开发了一类新型离子液晶；两亲性羧酸与2-氨基醇形成的盐，或者羧酸与两亲性2-氨基醇形成的盐，具有强烈的呈现热致液晶相的倾向。由于分子间相互作用的非共价性质，两种组分中的一种可以很容易地与另一种分子交换或转化为另一种分子，而不会扭曲原始的液晶结构。此外，两种组分都是常见的有机分子，并且很容易获得各种化合物。利用这些特性，我们成功地将双组分液晶应用于分子识别和反应的手性介质。这篇综述概述了我们最近的研究，以及与该领域相关的重要报告。
