设计合成了基于14-crown-4衍生物的高Li+选择性离子载体，并研究了其分子结构与离子选择性的关系，以获得高Li+选择性电极。根据所提出的两种类型的Li + 离子载体模型制备了11种14-crown-4衍生物，检查了离子选择性。通过在基冠环的乙醇桥部分引入庞大的“块”亚基，获得了优异的Li + 选择性离子载体，这有效地防止了由冠醚和大于Li + 的阳离子组成的2:1或3:1夹心型复合物的形成
Highly Li + -selective ionophores based on 14-crown-4 derivatives were designed and synthesized, and the relationship of their molecular structures and ion selectivities was investigated in order to obtain a highly Li + -selective electrode. The ion selectivities were examined with 11 kinds of 14-crown-4 derivatives, which were prepared a ccording to the proposed two types of Li + ionophore models. Excellent Li + -selective ionophores were obtained by introducing a bulky «block» subunit into the ethano-bridge section of the base crown ring, which effectively prevents the formation of a 2:1 or 3:1 sandwich-type complex consisting of the crown ether and cations larger than Li +
