Abstract

Designing and synthesizing ligands that can selectively bind a specific metal ion and undergo concomitantly color change are worthwhile subjects in host-guest chemistry. This paper provides such an approach where our attention is focused on lithium.'Several macrocyclic ligands have been known as lithium binders, but they also tend to bind other guests2 Recently, we reported ion-selective coloration with crowned (dinitropheny1) ...
