为了开发高性能的化学离子传感器，作为传感器离子传感元件的离子团的优化设计是一个重要的研究领域。本文通过对碱金属离子、碱土金属离子和铵离子离子载体的设计和合成的讨论，介绍了离子载体化学的一般概念和知识。在设计离子载体时，有几个重要的因素可以分为两类；一种是“结合性质”，它提供了离子结合原子或离子团本身，另一种是“立体特异性因素”，它涉及离子-离子团复合物的结构。基于这两个因素提出的多种离子载体分子模型，成功开发了Li+、Na+（碱金属离子）、Mg2+、Ca2+（碱土金属离子）和NH4+的高离子选择性离子载体。讨论了这些离子载体的发展情况，并对合成的90多种离子载体的结构离子选择性特性进行了预期和意外的研究结果。
For developing high performance chemical ion sensors, the optimal design of ionophores, which are used as the ion sensing component for the sensor, is one of the most important areas of investigation.Here I report the general concept and knowledge of ionophore chemistry through a discussion of the design and synthesis of ionophores for alkali metal ions, alkaline earth metal ions and the ammonium ion.There are several important factors when designing ionophores that can be divided into two groups ; one is 'binding nature' which offers the ion binding atoms or groups of the ionophore itself, and the other is the 'stereospecific factor' which concerns the configuration of the ion-ionophore complex.Based on several ionophore molecular models, which are proposed with the consideration of these two factors, highly ion-selective ionophores for Li+, Na+ (alkali metal ions), Mg2+, Ca2+ (alkaline earth metal ions) and NH4+ were successfully developed. The stories for developing these ionophores were discussed with the expected and unexpected results on the structural ion-selectivity features of more than 90 kinds of synthesized ionophores.
